The best radar detectors: Expert recommended

7 min read

When cruising down a lonely stretch of highway, it’s easy to get swept away and forget about the pressure of your foot on the gas. Next thing you know, you might be getting a pricey speeding ticket or even a date in traffic court. If only you had a radar detector.

A radar detector notifies you when your vehicle’s speed may be monitored by law enforcement. This allows you to find police before they find you, allowing you to slow your speed and correct your driving. In short, radar detectors can help you drive safer while saving you money with fewer tickets. They are legal in only two areas (Washington, DC and Virginia).

While searching for the best radar detectors, you should consider the following factors: 

  • Features: There are several bonus features you may find from model to model, such as GPS connectivity or false alert detection. These features can greatly simplify use and improve your chances of picking up on radar. 
  • Display: Visibility is a critical factor when selecting a radar detector. The best radar detectors come with an OLED display that provides greater clarity and color for your images.
  • Cost: Budget is a primary concern for many users, so we look for the best affordable radar detectors that come at a reasonable cost for their features.

When researching each radar detector featured on this list, I kept these criteria in mind:

  • Legality: Not all states or cities allow the use of radar detectors, or radar jammers. Each model on this list has been ensured to follow federal guidelines for radar detection, but be sure to check all state and local laws before purchasing.
  • Installation: Setting up a radar detector shouldn’t take all day or require special knowledge. Each model on this list has been chosen for its easy setup and user-friendly controls.
  • Consistency and reliability: A radar detector should give you clear and consistent warnings each time it picks up a radar signal. Each model on this list was chosen for its reliability based on customer reviews.

While federal law only bans radar detectors from being used in commercial vehicles, use in personal vehicles is regulated at the state and municipal level. Make sure you consult all applicable laws before you purchase a radar detector. 

A radar detector, well, detects radar signals. These devices search for signals given off by police radar scanners and alert you to their presence, allowing you to correct your speed or other driving faux pas and avoid a ticket. Radar detectors are generally legal across the United States, except in commercial vehicles. Though it is best to check state and local laws before purchasing anything.

A radar jammer is something very different, and very illegal. Both federal law and FTC regulations prohibit the use of radar jammers, as they intentionally interfere with radar communication systems to provide false readings. Offenders, even first-time offenders, can face heavy fines, equipment and property forfeiture, and even prison time. 

The cost of a radar detector significantly varies from a few hundred dollars to more than a thousand dollars. The best radar detectors range in price from $150 to less than $700, depending on the model you choose.
