Our Approach

In order to ascertain which radar detectors would be best for rideshare driving, we researched those products that would be more useful to a large range of shoppers. Those factors taken into account include the item’s availability, price, and quality. User ratings and those that tested and evaluated were also considered.


Is it legal to install a radar detector?

Currently Washington D.C. and Virginia are the only two places in the US where radar detectors are illegal, according to the Electronic Code of Federal Regulations. Using radar detectors in commercial vehicles or in federal parks and military bases is banned nationwide. Additionally, California and Minnesota do not permit window mounts. Though they are illegal in certain areas, an installed radar detector isn’t a moving violation, meaning insurance companies won’t penalize a driver for having one. Of course, you should check your specific state’s laws before purchasing as laws change all the time.

Is radar detector placement important?

A less noticeable detector leads to better feelings with law enforcement. A good place for it is mounted precisely under or over your rearview mirror, as near the mirror as possible. That way the detector can blend in better and be much less eye-catching.

Are radar detectors worth the money?

As a rideshare driver, a decent radar detector can be worth its weight in gold. With ticket prices rising all over, you could easily recoup the cost if it prevents you being clocked, pulled over, and fined.

How do radar detectors work?

Radar detectors serve as radio receivers to pick up frequencies in use by police radar guns. At the time the radar detector identifies a radar signal of a distinct frequency, an alarm sound and the visual display lights up to alert the driver.

What is the range a police radar can detect your speed?

Radar range is dependent on the vehicle’s size and shape. As an example, a full-size pickup’s speed can be detected from beyond a mile away, but a small, low sports car could rebound a very weak signal that might need to be within 500 feet of the radar device to be sensed.

What is a radar jammer?

Radar jammers are banned under federal law as a form of electronic warfare. Jammers put out interfering signals toward a radar gun, which blocks the receiver with extremely concentrated energy signals and scrambles the radars feedback. makes no guarantees to the usability or functionality of these products.
