Buying Guide: How to Choose Radar Detectors


How to Choose a Radar Detector

Let's be clear: radar detectors are legal in most states (not Virginia or DC for cars). They detect police radar so you can adjust speed before being clocked.

How Police Radar Works

Radar: Shoots radio waves, measures reflection to calculate speed. Detector picks up these waves at distance.

Laser: Point-and-shoot, nearly instant reading. By the time you're hit, they have your speed. Detectors alert to laser, but it's usually too late.

### What Matters in Detectors

Range: How far away can it detect radar? More range = more warning time.

False filtering: Modern cars have blind spot monitors using radar bands. Cheap detectors alert to these constantly.

GPS lockouts: Learn where false alerts occur and mute them. Essential for sanity.

Arrows/direction: Knowing the threat is ahead vs. behind helps you respond appropriately.

Frequently Asked Questions About Radar Detectors

Are radar detectors legal?

For passenger cars, legal in 49 states (illegal in Virginia, DC, and on military bases). Commercial vehicles: illegal federally. Some localities have restrictions. Check your specific area.

Do radar detectors work against modern enforcement?

Against constant-on radar: yes, very well. Against instant-on: only if another car is targeted first. Against laser: barely. Against automated speed cameras: not at all.

Why does my detector go off constantly?

Modern cars use K-band radar for blind spot monitoring. Cheap detectors alert to every passing car. Quality detectors with good filtering (and GPS lockouts) reduce false alerts dramatically.

Where should I mount my detector?

High as possible with clear view of the road ahead. Windshield near rearview mirror is common. Some states have windshield mounting restrictions—check local laws.
