How to Shop for the Best Radar Detector

best radar detector

Hitting the open road is one of the greatest joys for a motorist.

Especially when you can finally open up the throttle and feel the engine’s power push you back into your seat.

But sometimes that opportunity is rare, especially when accounting for busy traffic areas and rush hours. And other times, those wide open stretches of road are just too far away to be enjoyed regularly.

So what’s a motorist to do? There’s only so much fun to be had on city streets. And with posted speed limits, safety becomes a concern, as well as speed traps.

There are ways to avoid getting nabbed by a police officer’s radar gun.

Many motorists will opt to install a radar detector. Not only to avoid getting a speeding ticket but also to ensure they don’t push the limits too far in places they shouldn’t.

Finding the best radar detector isn’t difficult if you know what you’re looking for.

In this post, we’ll discuss how to select the best radar detector for your needs.

Choosing the Best Radar Detector

Some products are best purchased after conducting some research. Finding the best radar detector for your ride is one such purchase.

That’s why we created this guide to help you choose the best radar detector.

But first, let’s give a quick overview of how radar detectors work.

When a radar speed detection device is used, it emits a signal. Radar detectors work by, you guessed it, picking up on this signal and then alerting you to its presence.

There are a variety of signals used by these devices. As such, radar detectors are able to pick up most, but sometimes not all of these signals.

For example, police are well aware of the use of radar detectors. Due to this, they often use differing signals which are referred to as “bands.”

While most radar detectors have the ability to pick up these bands, not every radar detector is created equal.

The best radar detector for your road warrior should not only be able to pick up on these varying bands, but it should have a wide range of operation, too.

The best radar detector will be able to spot a speed trap and alert you way before you encounter it.

Now that we’ve covered radar detector basics, let’s move on to what you should look for when buying your radar detector.

Type of Detectors

The type of radar detector you choose for your needs is a matter of preference and practicality.

Typically you will encounter only three different types of radar detectors. These different types mostly refer to the type of mount used and how they are powered.

The first type is a corded device. These radar detectors will generally be mounted to the windshield of a vehicle with a suction cup or some other type of adhesive. This type offers a great range of detection and protection.

The second type is referred to as a cordless detector. Installation of these detectors is usually sleeker and cleaner in appearance. Additionally, these devices can be easily removed from one vehicle and moved to another.

The third commonly found type is remote-mount. These devices are permanent fixtures, meaning they are mounted to a vehicle in a permanent location. They are ideal if you’re looking for something sleek in appearance, and can’t be easily spotted by unwanted onlookers.


When shopping for the best radar detector, it’s important to consider the different types of modes the device has to offer.

For example, driving on a long stretch of highway is entirely different than driving in the city when it comes to picking up speed trap signals.

The right device for your purposes will have different modes to choose from.

A good mode feature to look for is what’s called “city mode.”

This detection mode takes into account the reduced range and congestion of urban areas and will disregard signals which are similar to radar guns.


When selecting the best radar detector for your vehicle, it’s important to consider what the device’s detection capabilities are.

Inexpensive detectors may have only one sensor which can only detect radar beams directly ahead of the direction you’re traveling. These types can’t detect the signals coming at you from the sides or from the rear.

The best devices will have 360-degree detection capabilities. As the name implies, these devices utilize additional sensors in order to pick up signals beamed from both the sides, as well as to the front and from behind.

Furthermore, devices with 360-degree capabilities are generally more reliable than other models. They are generally more expensive than models with a single sensor.


As previously mentioned, police are well aware of the use of radar detection devices.

As a result, law enforcement will often employ the aptly named radar detector detectors (or RDD for short).

Some radar detectors include technology which allows for the recognition of these devices. These features are commonly referred to as “shielding.”

Many detectors will have “stealth” features. This shielding feature alerts you when RDD devices are encountered, and will even power down the radar detector itself.

Other more advanced detectors will offer what’s called “invisible” shielding. These devices offer the greatest protection as they are able to continue operating despite the presence of RDD technology.


Some radar detection devices have taken versatility to a new level with smartphone compatibility.

While these devices might be more expensive, the features offered are unique.

The radar detector might, for example, be paired with a smartphone for increased ease of operation.

Some apps will even keep drivers notified about traffic accidents and other hazards.

Furthermore, some devices will support apps which are supplemented with information regarding the locations of red-light cameras and permanent speed trap installations.


While anyone can buy one of these devices, it’s up to the buyer to make an informed decision on the best radar detector for their purposes.

It is also the responsibility of the operator to be informed about the local laws surrounding the use of radar detectors.

Why Everyone Needs a High Quality Radar Detector

high quality radar detector

Between photo radars, red light cameras, and police waiting in unmarked vehicles, it seems nearly impossible to avoid speeding tickets.

If you choose to speed, you’re likely to end up with plenty of tickets. These tickets are costly. And if you get enough, you may end up with a suspended driver’s license.

If you’ve gotten a speeding ticket or two, it might be time to invest in a high quality radar detector.

What Is a Radar Detector?

A radar detector is an electronic device that is mounted on the dashboard of your vehicle. The detector alerts drivers that a radar gun or sensor is in use ahead.

The radar detector detects electromagnetic emissions from radar guns, red light cameras, and photo radars.

The electromagnetic emissions also come from other electronic devices. One example is the automatic doors that are used in supermarkets and drug stores.

As a result, radar detectors may emit false alarms when a vehicle is passing one of these doors.

Different types of radars operate on different wavelengths. Radar detectors detect some of these wavelengths. Radar detectors can only detect Doppler radars, which are those used by police radar guns, red light cameras, and photo radars.

Are Radar Detectors Legal?

Radar detectors used to be widely banned, though not legally so.

When a police officer would pull over a vehicle and discover a radar detector inside, it was common for them to destroy it.

But thanks to lawsuits regarding the Communication Act of 1934, radar detectors are now legal in nearly every state in the U.S. Only Virginia and Washington D.C. prohibit their use in private vehicles.

Radar detectors remain illegal for use in commercial vehicles over 10,000 pounds, or less in some states.

This doesn’t mean that speeding is necessarily legal. But say that you don’t realize that the speed has reduced from one section of road to the next. Or perhaps you aren’t familiar with the area and aren’t sure what the limit is. Or you simply aren’t paying attention to your speed.

But say that you don’t realize that the speed has reduced from one section of road to the next. Or perhaps you aren’t familiar with the area and aren’t sure what the limit is. Or you simply aren’t paying attention to your speed.

Radar detectors are a great, legal way to avoid a speeding ticket.

What Makes a Radar Detector High Quality?

Not all radar detectors are created equal.

Choosing not to opt for a high quality radar detector may leave you with one that won’t protect you from speeding tickets.

A good detector will alert you of upcoming radar guns or sensors and give you enough time to safely slow down.

If you aren’t given enough of a warning, you’ll still be speeding when you pass the police officer or red light camera. As a result, you’ll still get a ticket.

Police radars operate on the wavelengths X, K, and Ka. A high quality radar detector will detect all three wavelengths.

If your radar detector doesn’t detect all three wavelengths, you may be at risk when certain radars are in use. For instance, your radar detector may detect a police officer using a radar gun, but not detect the radar from a red light camera. Or vice versa.

For instance, your radar detector may detect a police officer using a radar gun, but not detect the radar from a red light camera. Or vice versa. This may help you avoid some tickets, but it won’t keep you entirely safe.

How Can You Find a High Quality Radar Detector?

With so many radar detectors on the market today, finding the right one can be a challenge.

But doing your research and shopping around is essential. Otherwise, you may get stuck with the opposite of a high quality radar detector, and end up still getting speeding tickets.

To help you find a high quality radar detector, it’s a good idea to start by reading reviews.

The information on the packaging of a radar detector is always going to be positive. Every manufacturer of radar detectors is going to try to convince you that their product is the best on the market.

But the reality is that many aren’t effective, and are just a waste of money.

Reviews of radar detectors from people who have actually used them are the best possible way to find the right radar detector for you!

While reading reviews, it’s important to look for indicators that the radar detector worked for different types of radars. Also, pay attention to reviews that say that a radar is very prone to false alarms. While this won’t lead to more speeding tickets or malfunctions, it can be very annoying for drivers and passengers.

While this won’t lead to more speeding tickets or malfunctions, it can be very annoying for drivers and passengers.

How Avoid Radar Can Help

Finding unbiased reviews of radar detectors can be a challenge.

Many reviews may look unbiased but are actually from the radar detector manufacturers. As a result, the reviews are unlikely to be accurate.

If you want a high quality radar detector that actually works and helps protect you from speeding tickets, you need a review website that you can trust.

That’s where Avoid Radar comes in.

The unbiased reviews of Avoid Radar make it easier to find the right radar detector for you.

You’ll be able to easily separate the good from the bad. This makes it simple to figure out whether a radar detector is a high quality before you waste your money.

A high quality radar detector won’t be cheap. But choosing the cheapest radar detector on the market will cost you far more money over time.

Even one speeding ticket will likely cost you much more than even the most expensive radar detector available. Several speeding tickets and the costs of going to court will cost the same as several detectors.

Investing in a high quality radar detector from the start will save you hundreds or even thousands of dollars in tickets!

Know the In’s and Out’s of Radar Detector Laws

radar detector laws

Are you a fan of radar detectors? These handy devices have been around for as long as radar speed guns and have served as a useful way to avoid getting a speeding ticket.

While commercial available and very accessible, you shouldn’t just purchase a radar detector and start using it. If you want to start using radar detectors, you may need to get up to date on new radar detector laws in the US. Some states are moving to completely ban these devices, while others are much more lenient.

We put together a guide on how to use radar detectors safely and legally in the United States. Check out this handy guide to understanding radar detector laws below!

What Are Radar Detectors?

A radar detector is an electronic device used by many drivers to see if local law enforcement is using a radar gun nearby to detect their speed. Essentially, radar detectors notify the driver to slow down before reaching the law enforcement officer with the radar gun to avoid getting a ticket.

Radar detectors are available for purchase all over the internet in varying qualities and prices. There is a big difference between radar detectors and radar/laser jammers (especially when it comes to legalities) and we will cover those differences later.

Are Radar Detector Laws Illegal?

It’s pretty obvious why law enforcement would want to eradicate radar detectors through passing radar detector laws. With radar detectors, ticketing speeding vehicles become much more difficult.

Radar detectors are illegal on US military bases. You won’t be ticketed or arrested for using one, but you will be asked to remove the device until you leave the military base.

Federally, any commercial vehicle over 8,000 pounds is prohibited from using a radar detector– no matter what make or model you drive in any state.

However, in many states, using a radar detector is completely legal. In others, laws are significantly stricter.

If you’re thinking about purchasing a radar detector, live outside of a military base, and drive a car under 10,000 pounds, then it may be helpful to look into radar detector laws that are in place in your state. You might be surprised by what you find.

Are Radar Detectors Unethical?

That’s a good question. Despite the fact that radar detectors are legal across many states, the use of one of these devices can come off as unethical. Why else would you use a radar detector if not to be able to speed as much as you like?

This doesn’t always have to be the case. Quotas have to be met and more often than not, many people receive speeding tickets upwards of $300 or more for going little more than five miles over the speed limit. Many think that these types of speeding tickets themselves are unethical.

Using a radar detector can help already safe drivers slow down enough to avoid any kind of bogus speeding ticket a law enforcement office could try to pin on them. Rather than be used to break the law, radar detectors can be used to protect law-abiding citizens from unethical punishments.

Are Jammer And Laser Devices Legal?

A laser or radar jammer is very different from a radar detector. A laser jammer is used to prevent police from obtaining a speed reading by “jamming” the laser gun used. A radar jammer is a device that creates radio signals that interfere with radar detection devices.

Under federal law, radar and laser jammers are illegal. Being caught with one could lead to a felony, a huge fine, and possible jail time.

The government has been cracking down more on catching citizens with jammers, too.

Enforcement Bureau Chief P. Michele Ellison had this to say several years ago on the subject: “Jamming devices create serious safety risks. In the coming weeks and months, we’ll be intensifying our efforts through partnerships with law enforcement agencies to crack down on those who continue to violate the law. Through education, outreach, and aggressive enforcement, we’re tackling this problem head on.”

Radar Detector Laws By State

This guide can help you get an idea of what different radar detector laws are in different US states.


In the state of California, radar detectors are legal. However, there is a catch– they cannot be sitting or mounted on the inside of the car’s windshield.

This isn’t specifically because of the radar detectors themselves. In California, it is illegal to have any objects on the windshield do to driver vision concerns. You can definitely get a ticket if your radar detector is there.


In the state of Illinois, radar detectors are legal. Only private vehicles are allowed to use them, though.

If you’re caught with a radar detector in a commercial vehicle, you’ll be at risk for ticketing and possible confiscation. Confiscation is usually rare.


Like California, radar detectors are legal. They just cannot be mounted on or near the windshield due to visual obstruction of the driver. If you do mount your radar detector on your windshield, you’ll be at risk for a ticket but not much else.

New Jersey

Like Illinois, New Jersey allows private vehicles to mount and use radar detectors. Commercial vehicles are prohibited and illegally using a radar detector will result in a ticket and possible (although rare) confiscation.

New York

Radar detectors are legal for private vehicles, but not for commercial vehicles. Repercussions include ticketing and possible confiscation.


Radar detectors are completely prohibited in the state of Virgina, no matter what weight car you operate. They are also illegal to sell in Virgina under radar detector laws.

Getting caught in Virgina with a radar detector can result in a ticket (regardless of whether or not you were speeding at the time) and your radar detector will likely be confiscated.

All other states

Radar detectors are legal in the rest of the US states with no restrictions on private or commercial cars. Federal law applies.

Why You Should Invest in a High-Quality Radar Detector

radar detector

The need for speed is real.

And if you have a car that can handle it and miles of open road, it’s utterly tempting to put lead in that foot of yours.

But you’re not going to get much of a thrill when those red and blue lights flare up behind you.

There are ways to ensure that you don’t get caught testing out the limits of your sweet ride. But if you’re not careful you could still end up caught.

Here are a few reasons why you should invest in something more than a bottom of the barrel radar detector.

How Do Radar Detectors Work?

Before you can know exactly why you need a radar detector, you need to know some basics.

The radar guns that cops use aren’t magic. They use the science of radio waves to detect how fast a vehicle is moving.

The device both transmits and receives radio waves. Similar to how a bat uses echolocation to transmit sound and receive it a radar gun sends out radio waves and records when they come back.

The frequency of the radio wave changes depending on how far away or how close a vehicle is when moving to or away from the gun.

The radar gun measures these changes and calculates how fast an object is moving.

Traditional detectors only passively detect these radio waves. And radio signals are everywhere. It has to tune into the specific signal put out by police radar guns. Which fortunately isn’t top secret information.

The same technology used by police to track cars is used in sports to measure the speeds of balls and pucks and other sports things.

Thus this technology is not something kept in a vault for nobody to understand.

Unfortunately, with traditional radar detectors, a cop measuring you from behind might not register until it’s too late.


Because of the invention of the radar detector, police have become inventive. A laser technology that detects variable distances now exists. And the police have it.

It’s called LIDAR, and it stands for Light Detection And Ranging.

You traditional detector cannot “see” light as light is a completely different frequency than radio.

There are only two defenses against LIDAR, a laser jammer and knowing the limitations of the technology.

A LIDAR can only detect the speed of a vehicle accurately up to 1000 feet or 1 kilometer. Anything farther away than that is indefensible in court.

So, if you can know where the police typically hide or can glean information on where they are with community connections, then you will be safe from LIDAR.

A laser jammer can defend against LIDAR, but a police officer will know you jammed his laser. He will then follow you like a hawk above prey for the rest of your ride.

Why Would I Need A Radar Detector?

You may not even be a speed demon. You might follow the speed limit most of your life.

But there are unfortunate circumstances where you might have to speed or you might accidentally speed. And ignorance is no protection from the law.

There are several reasons why you might want a high-quality radar detector whether you typically speed or not.

1. You Just Purchased A High-Performance Vehicle

It’s quite well known that cops pay close attention to vehicles known for speeding. And by known for speeding we mean a prejudice as old as the roadster.

Corvettes, GTs, Ferraris, and anything popularly fast. Any sports car could be tagged in a police officer’s mind as “fast.” And if the car has a particularly large engine, with raw power behind that wheel, you may have to take some time to adjust to controlling the speed.

A lot of cars like this are designed so that you do not feel the speed until you are way above the speed limit. So getting a high-quality detector for your speed demon car is probably a good idea just in case.

2. You Live In A State Where Speed Signs Are Sparse

If you’ve driven through New Mexico, you’ll know this problem well. You’ll hop on an unfamiliar highway and realize you forgot to look for the speed limit.

Now you’re stuck guessing for a good 20 miles or longer.

If you want to drive worry free on an unfamiliar highway, you might want to consider a Radar Detector for your vehicle. It might save you from having to confront a police officer in no man’s land.

3. You Often Have To Drive Your Own Car For Work Trips

It’s easy to zone out when driving long miles. And if you have to do it often, you run the risk of, like the example above, missing a speed limit sign.

Depending on local laws, a small town may not post a speed limit but once before you hit the local Barney Fife traffic stop behind the one bar in town.

And by then you’ll be hanging your head in shame.

You can avoid this risk by putting a high-quality detector in your car. Since it’s very likely officers will be using a LIDAR gun, you’ll know for a while that you’re coming up on a small town with an ambitious one-man show.

4. You Already Have Points On Your License

Depending on state laws, you might not have much longer before your license is revoked. If you’ve been caught too many times, it’s probably time to install that radar detector.

You will at least lessen your risk of getting caught if you just can’t keep that foot off the pedal.

5. If You Want To Contest Tickets

Of course, if you already have a ticket, it’s too late for this one. But some detectors have GPS capabilities that measure and log your speed. You can use that information in court if you are wrongfully flagged for speeding.


As you can see, there are plenty of reasons why you might need to install a detector in your vehicle.

Why would you put a radar detector in your car? Let us know in the comments below.

Here’s How Radar Detectors Work

how radar detectors work

Perhaps you have just gotten a radar detector. Or, maybe you have used one for years and you wondered: how does this thing work ANYWAY? It is important to understand how radar detectors work when you own one. it also gives you the power to decide if the one you have is still effective and when it’s time to get a new radar detector as its an ever growing market and new technologies emerging every other Day.

In this article, we will Try understand what radar Detector is and what it does. Then we’ll cover how this applies to police radar and your radar detector.
Let’s get started!

What is Radar?

Radar, or Radio Detection and Ranging, is an object detection system. It can measure the distance to an object as well as the speed at which the object is moving.
To measure speed and distance, a radio transmitter and receiver are used. The transmitter sends out radio waves called radar signals in the desired direction.
Once the object is hit, the signals reflect back or scatter in numerous directions.The signals which reflect are essential. They reflect back onto the receiver and provide the desired information about distance and speed.
Just like freeze dried food, Jeeps, and GPS, radar was initially developed for the military and then repurposed and rebranded for non-military institutions and citizens.

Police Radar

Police radar uses these radio waves to catch speeding drivers.After World War II, radar was repurposed as police radar in the 1950s.Police radar is built with the radio transmitter and receiver in one object. To properly read the speed of a car, police radar needs to be stationary.
So long as it is stationary, police radar can be placed almost anywhere to get an accurate reading.

An officer can use police radar from their vehicle, place it in a shrubbery, or hide it behind a civilian vehicle. Sometimes, the police do not need to be there at all as many precincts use traffic enforcement cameras (TEC) mounted over or on the side of the road.

The police radar transmitter sends out radar signals, typically short reaching signals like K and Ka, in their desired direction. When it hits a moving car, multiple signals reflect back to the receiver.

The reading from the police radar or traffic enforcement cameras provides your speed. If you are over the limit the officer will pursue you and ticket you or a picture of your license plate will be taken from the TEC and you’ll receive a ticket in the mail.

How Radar Detectors Work

Your radar detector detects other radar signals. Ideally, those used by police radar.Radar detectors began to be used by citizens in the 1970s. Your radio detector acts as a receiver, no transmitter needed. The signals transmitted by police radar cast a wide net.
Your radar detector catches these signals from that wide net. When you are alerted of the police radar presence near you, you can slow down before passing the police radar.

When Radar Detectors Don’t Work

Radar detectors are imperfect, mostly as a result of other industries innovating their own technology.For instance, in recent years the auto industry has created many cars which are programmed to avoid a collision and boast adaptive cruise control.

For these guidance systems to work, they send out radio waves at a specific frequency. Guess which ones? The same frequencies that are used by police radar, most commonly K and Ka. This will render your radar detector useless.Even automatic doors, like garages and grocery store entrances, can use the same signal.
What help is your radar detector to you if it alerts you of police radar, new cars, and automatic doors if it can’t tell you the difference between one and the others? No help at all.

When Radar Detectors Companies Innovate

There have been encouraging innovations to radar detectors in the last few years.Several new models have been made which differentiate police radar from radar signals in newer vehicles.
New technology has been created and implemented which filters out the signals from collision avoidance and adaptive cruise control. Three companies leading the way are Escort, Valentine Research, and Stinger VIP.

1. Escort has identified the unique signatures of the guidance systems used in newer cars. They created a filtering algorithm which differentiates those signatures from police radar.The alerts you receive from an Escort radar detector are much likelier to be signals from police radar.

Escort radar detectors are intuitive as well. Each time it identifies a guidance system signature, it takes note and adds it to the library of signatures.
When a driver performs a firmware update to their Escort radar detector, it will add these signatures ensuring that most of the alerts they receive are from police radar.

2. Valentine Research built upon Traffic Safety Rejection (TSR). This means that it receives K and Ka signals, but delayed. This filters out the majority of false alerts caused by guidance systems, but it does mean that you’ll have less time (a few seconds) to slow down for police radar.

3. Stinger VIP is not a radar detector but provides better results. This spectrum analyzer also identifies your own cars radar signals.

The Stinger VIP was developed as a car computer with a spectrum analyzer. It performs “sweeps” of radar frequencies used by police.
It also filters out radar signals given off by your own vehicle. You can drive confidently knowing that your radar detector is receiving all frequencies used by police radar and cancels out the signals from your own car.

Make Informed Decisions about Your Radar Detector

If you have ever wondered how radar detectors work, now you know that there is a lot to know!When you know how radar detectors work, you have the power to decide if the detector you have is still effective and when it’s time to get a new radar detector. There are a variety of detectors to choose from.

How to Know if Your Radar Detector is Accurate

Do you ever wonder about the accuracy of your radar detector?

Radar detector technology is ever-innovating. This industry has:

  • replaced analog processors with digital processing chips;
  • incorporated digital voice alerts so that you can keep your eyes on the road
  • offers a variety of shields for privacy.

These steps forward are encouraging, however, the technology used by the auto industry and law enforcement continues to hamper radar detector effectiveness. So, how can you ensure that your detector is up to the challenge?

Read on to learn what provides an accurate reading from your radar detector.

New Radar Detector

An up-to-date radar detector will give you a more accurate reading.Today, using your outdated detector is pointless. Old radar detectors were designed to identify the frequencies used by police radars, X, K, and Ka.

This is bad for outdated radar detector users. As in the radar detector industry, the auto industry has made many innovations to its products.In the last few years, numerous cars have been produced which feature collision avoidance as well as adaptive cruise control systems. These features utilize the same frequencies as police radar to function.

As you drive with your outdated detector, it will let you know of police radars near you but it will also alert you about every new car on the road. It’s up to you to guess which is which.

This does not help you avoid police radar and it is annoying. Outdated detectors are just as helpful as not having a radar detector at all. Updating your detector is essential.

Newer detectors do their best to differentiate the signal produced by collision avoidance and cruise control systems from police radar.

None of these new detectors provide 100% accuracy, however, when they do alert you it’s much likelier that the frequency it’s reading belongs to police radar.

These newer radar detectors come with a variety of assistive features.

Detector Type

A factor which can affect the accuracy of your reading is the type of detector. Each detector type has certain strengths and features which will appeal to certain people based on their driving habits and their environment.

There are three types of detectors:

  1. The corded detector. This type of detector mounts directly on your windshield with suction cups. Corded detectors are the least obstructed of the types and so they provide the best range of detection.
  2. The cordless detector. This detector is great for the multi-car owner. It can be moved from car to car and it installs more easily compared to corded detectors.
  3. Remote-mount detector. This detector mounts onto your car permanently, but they are designed to be a seamless install. This detector is ideal for the driver concerned about the robbery of items in their car.

The corded detector comes out on top as the most effective, but if you want one radar detector for multiple cars or you are concerned about the robbery of items in your car there are viable options for you.

Detector Mode

Another helpful feature is detector mode. Use the right detector mode at the right time and you will know that you have a more accurate reading.

There are two modes: city mode and highway mode.

Utilize city mode when you’re driving in town. City mode reduces the range for the frequency measured.

This means that you won’t get signals from police radars far away which wouldn’t affect you. This also means that frequencies used in your car and home, like automatic garage doors, won’t cause your radar detector to alert you either.

Utilize highway mode when you’re on the highway. This mode increases the range for the frequency measured.

On the highway, you drive a greater distance faster. Here, it is important that your radar can read further away.

Using each mode when appropriate provides you with the right alerts at the right time.

Laser Detection

If you have worried that your readings are not accurate, it could be because the police radar being used is actually police laser.

The light beam from a laser is narrower than that from radar. This allows for precise aim and is part of why laser beams are considered to be more effective than radar.

If you do find out that the device being used in your locale is laser and not radar, invest in a laser detector.

A basic laser, a detector with one laser, can only detect signals from in front of you. It’s better than nothing but it doesn’t provide the comprehensive results you need when you’re on the road.

Advanced laser detectors, a detector with two lasers, read for laser signals from every direction.

You can drive confidently knowing that you are getting an accurate reading.

Inaccurate Readings Caused by Your Car

Metallic elements in or on your windshield can cause inaccurate readings.

Some cars are produced with metallic in the windshield. Unless you would like to replace your whole windshield, there is nothing you can do to regain the accuracy of your detector

Sometimes metallic elements are placed on the windshield: many film tints are commercially available for drivers to put on their windshield. People can unknowingly compromise the integrity of their radar detector when they get film tints applied.

Not all film tints have metallic elements. Doing your research before you buy and apply film tints can save you a lot of money and grief. You can have your film tint and detector, too.

Accurate Readings

You no longer have to wonder how accurate your radar detector probably  ! You know what makes an effective detector for the task.

Using newer detectors will give you a more accurate reading and provide you with a defense against police radar and lasers.

Choosing the right detector type for your car and environment is important. Using the city mode or highway mode when appropriate will contribute to an accurate and helpful reading.

Considering alternative detectors and understanding the impediments to accuracy caused by your car is key.

Check out Avoid Radar for more information and advice about radar.

Wireless Radar Detectors! How They Work?

Imagine you buy a radar detector, get into your car and stick the detector onto the windshield to discover that the cigarette lighter cleverly located at the back of the console requires a detector cord three feet longer than what you have. In this case three things can be done; re-engineering the entire electric system of the car (overboard), Fabricate a longer power cord for the radar detector (mild, but why bother) or get a wireless radar detector(best approach to solving problem).

Improvements in the manufacturing technology of Radar detectors have seen newer versions smaller, more digital and cordless. It is important to be cordless, mobility is enhanced and this safeguards against laws which prohibit objects on the windshield.

A radar detector in general is an uncomplicated device used by motorist to detect police radar. Radar fundamentally works by bouncing a radio signal off of an object, thus any receiver tuned to the same frequency can detect the signal and often at a greater range than the radar unit itself can detect the reflected signals. There are many different detectors on the market, with varying sensitivity and different options, but they are all fundamentally radio receivers. So in actual sense it is a radio tuned to the same frequencies as police radar.

Why wireless radar detectors

All over the US corded detectors are the most common and their fundamental feature of being mounted on a windshield by using suction cups makes them the most regulated form of radar detector.  Wireless detectors are more of the new generation kind of detectors. It can be placed anywhere in the car meaning a cleaner form of installation.

Most wireless radar detectors come with new cutting edge technology that brings them to this new digital age of ours. This means there is a higher probability of wide-brand frequency detection. This is the essence of the detector; if for a moment the radar detector is unable to detect the frequencies used by the police then it is no better than a useless radio device.

Modern features would mean a detector equipped with GPS systems. This is very useful in that it increases the consciousness of the detector; if we are concerned about the police and safety then a detector with a GPS system incorporated is very important. It allows the detector know and be able to alert on how fast the vehicle is travelling when any radar activity is detected.

Radar detector laws

Except for Virginia and Washington D.C, the use of radar detectors is legal all over the US and this is so because they are not regulated, there isn’t one legislative document out rightly making it illegal. However California, Florida, Minnesota, New Jersey and Pennsylvania prohibit the mounting of objects on the windshield. This makes it illegal to use radar detectors that require mounting onto the windshield in these mentioned states. It should be noted that this applies to passenger vehicles. As concerns commercial vehicles weighing over 10, 000 Ibs there is a federal law prohibiting their use without exception. It is very important to have this in mind before going out to buy a radar detector, so you can know what kind to buy or if you aren’t to buy it at all.

Police radar

To completely understand how wireless radar detectors work it is absolutely important to know how police radar works. This will help in understanding the features that are a must have by the detector you so desire.

The day-to-day police radar is the radar gun, which is a hand held device used by pointing at a vehicle and pulling the trigger, the speed of the vehicle is immediately displayed on the screen of the radar gun and we know the rest if we are in violation.

In comparison to modern wireless radar detectors, most modern police radar guns use what is called the k-band, which was introduced in the late ‘70s. These guns have a range of about a quarter mile and can be detected anywhere within two miles depending on the conditions. The ka-band was introduced later, toward the end of the ‘80s, and uses an even shorter wavelength. This is the same band used by photo-radar machines and is also where most recent radar development has been focused, including the development of the so-called “stalker” guns which can only be detected by sweeping the entire ka-band, not just the portion used by photo-radar. Police radar originally used the x-band, which is a much lower frequency, but it has been largely phased out.

Police radar uses the Doppler Effect to measure speed. This simply means wave lengths get shorter as the source comes closer and longer as it goes away. So, the closer it moves it effectively raises the frequency. This in effect gives a perfect estimate of the speed of the vehicle


The radar detector is about knowing where the police have focused their speed enforcement efforts and not a license to speed with impunity or guarantees invincibility while speeding. The cordless operation of the radar detector exacts some compromises because of battery life. This has forced designers to walk a tightrope while designing the wireless radar detector because incorporating all sensitivity features means lowering the longevity of battery life. This may affect efficiency as sensitivity has to be regulated and in some cases compromised

The new radar detectors might be a little bit pricier than the most we are used to and it might not be invisible from radar detector detectors. This might bring unwanted Police attention and might in a larger sense prove a certain intention to speed.

Because it is not placed on the windshield this reduces the height advantage and reduces the accuracy in detecting the police radar due to the obstruction from the vehicle’s metal.


Thought modern wireless radar detectors might be more expensive to use. The flexibility in its usage and its improvement in wide-brand frequency detection is essential to all radar detectors and this is what it brings to the table as a fact.

Radar Detector Laws! Is Radar Detector Legal?

Most drivers have been at a particular point in their driving experience, when we ask ourselves “how can I beat the ticket.” It is pretty easy if you understand the intricacies of being caught for exceeding speed limits in the first place. It is well known that the police officer issuing the ticket used a laser gun to detect the car speed. Out of the genius of our minds, the radar detector came to being.

They alert motorist and let them know if their speed is being monitored by a police using a laser gun, cool isn’t it. By using it motorist are able to reduce the car’s speed before ticketed for speeding. However because of the several implications of this devise and the fact that it can affect certain radio frequencies, is radar detector legal to use it in some states and on military property throughout the entire country? Let dig it a bit.

Federal laws carry with them wider applicability, this notwithstanding speed limits vary in various states making it difficult for strict federal laws to be enacted on the topic, so they do so in a much broader legal manner.


Communications Act OF 1934
The piece of legislation passed by congress in 1934 with which intent lied on interstate and foreign commerce on the regulation of wire and radio transmissions has been given a progressive interpretation by the Federal courts to include the legal foundation for states to regulate devices such as radar detectors. Detractors from this approach argued that the law is a response to national defense issues caused the evolution of foreign and domestic advancements of monitoring technologies. Whereas proponents postulate that interstate commerce provisions of the 1934 ACT applies to radar detectors because a lot of commercial entities make use of it.

The Federal Communications Commission (FCC)
The FCC as a federal government agency has respected is boundaries as purview over radio detectors is ceded to the states. However the FCC has tried to impose a general legal language as it applies to radio devices such as, ham radios, as well as other devices that can receive police transmitted frequencies. Be as it may since 1993 when the broad legal language was incorporated into a handful of regulations, no court has made a connection between ham radio receivers and radar detectors.

STATES AND RADAR DETECTOR LAWS                                                                      

Windshield mount laws
There are five states that are against mounting devices on the windshield that can be seen by lawful authority to impair the vision of the driver:

  • California
  • Minnesota
  • Pennsylvania
  • New Jersey
  • Florida.

There is a little twist to this because except for Minnesota that specifically bans radio detectors hanging from the windshield the rest bans anything hanging from the windshield. Take note that these states do not specifically ban the owning and using of a radar detector. It just happens that most radar detectors are used and best suited to be placed at the windshield. Citizens of the Sun Shine State of Florida have taken a class action against the windshield mounting law and no conclusive ruling has been reached on it yet.

Commercial Vehicles
ALL 50 states and the District of Colombia in the US prohibit the use of Radar Detectors on commercial vehicles. States specify the weight of the commercial vehicle and in some cases all vehicles above a certain weight are also prohibited. The states of Illinois and New York cap theirs at 10 000 pounds for commercial vehicles and 18000 pounds for all vehicles. In this regard, commercial vehicles above 10000 pounds and all vehicles over the weight of 18000pounds are prohibited from using the radar detectors.


Virginia and Washington D.C are unique when it comes to Radar detectors. Not only is it illegal to use it in Virginia and D.C it is illegal to be in possession of it or for traders to trade in radar detectors. The reason for this in the state and territory is because radar detectors interfere with federal government transmitted electronic waves. Military vehicles are the only exception in using radar detectors in both jurisdictions. The penalty when found guilty of using one varies; it becomes aggravated by prior offences committed by the offender.

In 1998 there was an attempted federal move restrict the use of Radar Detectors but the move didn’t gain the momentum to be able to make it to the floor. The restriction thus remains under the control of all states. No state out rightly makes radar detectors illegal except Virginia and Washington D.C. other states have restrictions that limits its use and particular models.

It is very important for everyone to stay abreast with laws restricting devices like Radar Detectors as well the introduction of such legislation, not forgetting case law interpreting laws that may apply to Radar Detectors. Why we all should watch out is because traffic citations bring in revenue to states, therefore it would not be a surprise to see cash strapped states make the move to out rightly ban radar detectors. The fines that come out of from speeding have become a lucrative source of income for local and state governments.

Common Features of a Good Radar Detector

Common Features of a Good Radar Detector

Getting a good radar detector can be considered as a good investment. This is because doing so provides you with the needed protection against radars and lasers commonly used for speed enforcement.

Given the said benefits, it is really important for you to get the best radar detector in the market. But due to increasing number of options in the market, selecting the best from what is available might be difficult.

Fortunately, you can simplify the selection process by looking at the common features of a good radar detector such as the following.

Longer Detection range

Radar detectors are basically used to alert drivers of the presence of radar and laser signals used by traffic police to apprehend motorists who are driving beyond the prescribed speed.

Due to this, go for a radar detector with a longer radar detecting range. This is because such device can provide prompt alerts and ample time to reduce speed before getting into trouble with speed enforcers.

Although a lot of radar devices claim that they provide longer detecting range, go for the models that can provide alerts at least a mile away from the sources of the radar or laser signals detected.

But since the detector’s range varies depending on presence of obstacles in a particular area, go for the products with “highway” and “city” mode since these can be adjusted to meet the possible challenges present on the area where the vehicle is driven.

POP-detecting Feature

Speed enforcers are now using radar guns with POP modes to deal with motorists who use radar detectors. This is because the POP mode allows the radar guns to send short signals that a lot of radar detectors cannot pickup.

Due to this, it is important for you to consider the idea that a good radar detector should include a POP-detecting feature. By having a device which is equipped with this feature, you will surely avoid getting a speeding ticket from enforcers who use POP-equipped radar guns.


The portability of a radar detector is another important feature that you should consider in during the selection process sense a portable device provides a lot of useful features.

First this characteristic allows you to conveniently position the device in areas such as the dashboard and windshield. Second, a very portable and cordless detector can be easily transferred from one car to another making it a top option among drivers who are fond of switching cars regularly.

On top of that, you can easily conceal a portable detector when it is needed to be hidden or kept to prevent speed enforcers from discovering that you are using such device.

GPS Navigation Equipped

Many experts agree that a detector which is equipped with the GPS navigation is better compared to those that are not sold along with such feature.

This is because the GPS technology is one of the features that enable the device to provide warnings and possibly the actual positions of potential sources of threats such as the red traffic lights, fixed speed cameras mounted on strategic areas and other speed traps employed by the authorities.

In addition to that, a radar detector with GPS Navigation can help you free some space from the car’s dashboard as well as help reduce your expenses.

Instead of buying a separate GPS navigation device to aid you during the drive and incur additional expenses, you will just need to activate the said function on the device to obtain the needed navigation assistance.

Can Detect All Radar and Laser Bands

Finally, you should also understand that a good radar detector is capable of detecting all radar and laser bands present in the areas where you drive the car. A lot of experts view this as an important feature since it allows the device to provide you with warnings upon detecting different laser and radar bands.

Thus, you will not be caught off-guard in the event that the speed enforcers in particular area are using radar guns that make use of different bands. For best results, you can go for the models that provide rear and front protection since this will keep you protected from all sides.
