Utah Radar Detector Laws: Detectors, Jammers and Drivers

Utah law expressly addresses radar jamming devices. Federal rules separately restrict detectors in commercial motor vehicles; check current statutes for your situation.

Utah radar detector laws should be read by separating passive detection from active interference. Utah Code section 41-6a-609 prohibits operating a vehicle with a radar jamming device and knowingly using one to interfere with law-enforcement radar or laser. Federal regulations also prohibit detectors in commercial motor vehicles. For a passenger vehicle, confirm the current Utah statutes and the exact function of the device before use; product labels are not legal advice.
