While we do not condone speeding, we acknowledge the fact that drivers do exceed the speed limit from time to time. Whether it’s on a rural part in the U.S. with a long and uneventful freeway, or the road has just opened up after being stuck in traffic, drivers like to stretch their car’s legs every now and then. That’s where a radar detector comes in handy, so long as they’re legal in your state (currently illegal in Virginia and Washington, D.C.).
Radar detectors are designed to warn you of police presence and the use of speed detection hardware. They’re an in-car device that mounts inside your vehicle, similar to a dash cam or handheld GPS device.
When shopping for a radar detector, you’ll likely notice they come in a wide range of prices. These devices make a strong case for you get what you pay for, as cheaper models tend to be less accurate and return false positives.

Everything You Need to Know About Radar Detectors
We get it. Every now and then you just need to travel above the speed limit, whether it’s an open road or you’re trying to get through traffic. AutoGuide.com does not condone speeding, but we’re also realistic that not everyone stays below the speed limit at all times. That’s where a radar detector can come in handy, potentially saving you from an expensive ticket if they’re legal in your state. When it comes to U.S. states, currently only Virginia and Washington, D.C. have made radar detectors illegal.
Shopping for a radar detector is no easy task, especially if you don’t have a lot of experience with the technology. There are likely words and bands you don’t recognize in various product descriptions, so we’re here to help make things as clear as possible.
What is a Radar Detector?
In the most basic sense, a radar detector will warn you of possible upcoming police or other law enforcement who are monitoring speed. Good radar detectors are able to detect a wide variety of bands at long range, giving you ample time to slow down before getting a ticket. Essentially, a radar detector hones in on the band signal coming from a speed gun, alerting you through a visual or auditory signal.
What are all the Different Bands?
In the U.S., police radar guns operate on three frequency bands: X, K, and Ka. The oldest of the three bands is the X-band, which is being phased out with newer and smaller DSP Ka-band radar guns. The K-band is still common, while the Ka-band offers wider coverage for law enforcement to detect speeders.
There is also POP radar, which was designed to transmit a single radar transmission that’s extremely short to render radar detectors obsolete. Since then, however, radar detector manufacturers have developed technology to detect POP radars.
Along with three radar bands and POP radar, law enforcement in the U.S. also use one laser band.
What Exactly is Radar?
According to Escort, a reputable manufacturer of radar detectors, there are over 100,000 radar guns being used in the U.S. On a daily basis, across multiple shifts in multiple vehicles, there are potentially 100 million radar traps in the U.S. every year. To explain how radar works, the company uses a simple analogy:
“Think of a guard performing his security check at night. From hundreds and hundreds of yards away we are able to see his progress as he searches back and forth in the dark – yet, the guard can’t see us,” Escort explains. “In fact, the guard can turn the flashlight directly at us and still never see us! Why? Because in order for us to become visible to the guard, there must be sufficient light reflected off our our clothing and returned to his eyes before he can see us. Notice – we can always see the flashlight even though the guard can’t see us. That’s because we only need a small amount of light from the flashlight to see it in the dark.” In a way, that’s how a radar detector works, giving the driver an advantage when using one.
A high-quality radar detector is designed to detect the energy from a radar gun, even though the radar gun won’t be able to see the driver until they’re getting closer.
What About Laser?
Laser guns aren’t as popular as radar guns, with Escort estimating 35,000 in use today. Unlike radar guns, law enforcement using a laser gun must do it from a stationary position, which means you’ll likely see them being used near highway overpasses and from interstate medians. They are also affected by certain weather conditions such as rain and fog, and in most cases, cannot be used through glass.
Laser guns use a very narrow beam of light to target vehicles, with the beam being fired at a vehicle at the speed of light. Once the light hits the target, the light reflects off and back to the laser gun. The laser gun uses the reflected light pulses to calculate a vehicle’s speed, based on the amount of time it takes for the light pulses to come back to the gun.
A good laser detector will be able to see the laser source and the reflected light signals that bounce off other objects. Typically when a group of cars is being targeted, you can expect your laser detector to alert you.
What About Radar Detector Detection?
In the U.S., radar detectors are legal to use in non-commercial vehicles so long as you aren’t traveling in Virginia or Washington, D.C. Since they are illegal in Virginia and the nation’s capital, as well as in commercial vehicles, some areas use radar detector detectors, also known as RDDs.
There are two common types of RDD technologies: VG-2 and Spectre. VG-2 works by detecting the oscillations on a single frequency band, while Spectre is a more sophisticated technology that operates on several frequency bands and can pick up more emissions from a radar detector.
More expensive radar detectors will offer shielding and protection against VG-2 and Spectre. If RDDs are a concern to you, make sure you grab a radar detector that prevents VG-2 and Spectre.
Types of Radar Detectors
Before you start researching individual products, you should determine the type of radar detector you want. Most radar detectors are corded units, which means they must be plugged into a cigarette lighter for power. These are typically the best performing detectors and are the most reliable, so long as you can deal with the sight of a cord dangling from your windshield.
If you travel a lot or often have to switch cars for whatever reason, you may want to consider a cordless detector. These are powered by batteries, which means you can take them on the go. Just make sure you keep a spare set of the batteries it needs, just in case it runs out of power.
The third and least common type of radar detector is a remote-mount detector. These are permanently mounted to your vehicle, allowing for a clean installation that could be out of sight from potential thieves.
Features to Look For
Along with researching the bands a device can detect, make sure to take a look at any more advanced features a particular radar detector has to offer. These features range from built-in GPS technology, smartphone compatibility, auto mute, safety alerts, and multiple city/highway modes.
Radar detectors with built-in GPS technology have a few benefits. Some can adjust their sensitivity based on how fast the vehicle is traveling, reducing the need for switching between city and highway modes. Another benefit is that some radar detectors will remember certain areas that you drive through frequently, alerting you when you’re approaching something of interest. Some units provide warnings for upcoming speed drops and red light cameras.
Detectors that have smartphone compatibility normally take advantage of an app that works alongside your radar detector. Escort Live for example, warns of upcoming alerts received and reported by other users in the area, in addition to giving access to local speed limit data for over-speed alerts.
Regardless of how expensive or advanced a radar detector is, there’s always a chance it will report a false negative. Devices equipped with an auto mute function will automatically decrease the volume of a warning so that it doesn’t become annoying. This is a feature you may want to look for if you often drive in city or urban areas, where false positives are most common.
Some radar detectors feature a safety warning system, which keeps the driver informed of possible situations that require attention, such as emergency vehicles, road hazards, and road construction delays or detours.
Lastly, multiple city/highway modes help to filter K- and Ka-bands to prevent false detections. Most modern radar detectors come with city/highway modes.
