Radar Detectors in Texas: What Drivers Should Know

For a Texas passenger vehicle, check the current state code and keep any device from obstructing your clear view. Commercial vehicles face a separate federal restriction.

If you are researching a radar detector in Texas, separate the device question from installation. Texas Transportation Code §547.613 addresses objects on vehicle windows that obstruct or reduce the driver’s clear view; the current statute is the source to check for your circumstances. Federal regulation 49 CFR §392.71 prohibits radar detector use in a commercial motor vehicle. For passenger-car selection, compare detector bands, false-alert controls and mounting instructions, then check the relevant model guide.

Common questions

Questions before you buy

Are radar detectors legal in Texas?

Texas law does not list ordinary radar detectors as prohibited equipment for passenger cars in the cited vehicle-equipment chapter. Federal restrictions apply to commercial motor vehicles; check current law for your vehicle.

Can I mount a radar detector on my Texas windshield?

Texas Transportation Code §547.613 concerns objects that obstruct or reduce clear view. Choose a placement that does not impair visibility and check the statutory exceptions and current text.

Can truck drivers use radar detectors in Texas?

Federal regulation 49 CFR §392.71 prohibits use or possession in a commercial motor vehicle. The federal rule applies regardless of a state’s passenger-car rules.

Are radar jammers legal in Texas?

Texas Transportation Code §547.616 addresses radar interference devices. A detector receives signals; a jammer is a different device, so do not treat their rules as the same.
