Radar detectors are completely legal to use in non-commercial vehicles in 49 states. Virginia and Washington DC are the only places in the United States that currently ban radar detectors. Radar detectors are illegal in most Canadian provinces. Radar detectors are also illegal on military bases.
Radar and laser jammers are illegal in Minnesota, Virginia, Utah, Oklahoma, Nebraska, and California.
Radar detector use in commercial vehicles has been prohibited in the U.S. since 1995. Because laws and regulations tend to change, you should verify the legality of radar detectors in your state prior to purchasing one.
Note: Radar detectors are prohibited in all commercial vehicles over 10,000 pounds. The following are the official regulations for commercial motor vehicles.

The Beltronics Pro RX65 Radar detector is the most advanced radar, laser and safety detector ever designed by Beltronics. Of course, you can trust Beltronic's proven ability to outperform where it counts most — industry leading sensitivity to today's low-powered traffic radar guns.
The Whistler 1793SE All Band Laser-Radar Detector is Whistler's "top-of-the-line" model. It is a great detector for the price. Tests have shown that it has almost equal the range of the high end models from Bel and Escort at only a fraction of the cost.
The WHISTLER PRO-73 Radar / Laser Detector features POP Mode Detection, Real Voice Audio Alerts, Stay Alert Mode, Total Band Protection, and three (3) City Modes. The Whistler Pro-73 is a quality detector, with an impressive array of necessary and useful features.
The WHISTLER PRO-58 Radar / Laser Detector radar detector is a high end model from Whistler's high performance Professional Series. This model detects the new POP mode feature of some radar guns, and incorporates a high gain optical lense for increased laser sensitivity. This detector also features 3 City modes for a reduction in false alerts. An Alert Priority feature makes sure the most important alert is displayed if multiple alerts are detected. This model also includes a hard wire kit, and a two year manufacturer warranty.
The RADAR DETECTOR, XRS-9780, 11 BAND, offers 11 protection bands, POP radar sensing and safety modes that detect emergency vehicles. Get all the feature-packed advance radar warning you'll need to be king of the road. The Pro 9780 retails around $200.
is possibly the best performing radar detector on the market today. For years, Escort has been leading the industry in performance and quality and the 8500 X50 is no exception!
