01
Passenger-car use and detector possession
The current Texas Transportation Code chapter on vehicle equipment includes provisions on radar interference devices and window obstructions, but no general prohibition on ordinary radar detectors in passenger cars in the cited sections. Check the latest statute for your situation.
02
Keep the driver’s view unobstructed
Texas Transportation Code §547.613 addresses an object or material on a windshield or window that obstructs or reduces clear view. Choose a mounting position that does not impair visibility.
03
Commercial motor vehicles have a federal restriction
Under 49 CFR §392.71, a driver may not use a radar detector in a commercial motor vehicle or operate one equipped with or containing a detector. This is separate from Texas passenger-car rules.
04
Do not confuse detectors with jammers
A detector receives signals. A radar interference device is designed to interfere with speed-measuring equipment; Texas Transportation Code §547.616 prohibits use, installation or operation of such devices in a motor vehicle.
05
Recheck the rules for your trip
Vehicle class, installation and changes in law can matter. Review the official Texas statutes and applicable federal regulation before relying on a general summary.
Common questions
Questions before you buy
Is a radar detector legal in Texas for a car?
The cited Texas code does not ban ordinary radar detectors by name for passenger cars. Device placement must still comply with the window-obstruction rule.
Are radar detectors legal in Texas for commercial trucks?
No. Federal regulation 49 CFR §392.71 prohibits their use or possession in a commercial motor vehicle.
Can a radar detector be placed on the windshield?
Texas law prohibits a window object that obstructs or reduces the driver’s clear view, subject to statutory provisions. Mount it so visibility remains clear.
Are radar jammers legal in Texas?
Texas Transportation Code §547.616 prohibits radar interference devices in motor vehicles. A jammer is not the same as a receive-only detector.
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.
Ordinary passenger-car detectors are not prohibited by name in the cited Texas equipment provisions. Commercial motor vehicles face a federal restriction, and windshield placement must preserve visibility.
