Guide
Texas law specifically prohibits radar interference devices in vehicles. The statute does not state a general ban on ordinary radar detectors; vehicle class and federal rules still matter.
Texas Transportation Code § 547.616 defines and prohibits radar interference devices, including jammers, in a motor vehicle. That section does not itself set out a general prohibition on a conventional receive-only radar detector. This is a plain-language summary, not legal advice.
A radar detector receives signals and warns the driver; a radar interference device is designed to interfere with, scramble or disrupt speed-measuring radar or laser. Texas law prohibits using, attempting to use, installing or operating the latter in a vehicle, and also restricts its sale or purchase for that prohibited use.
Federal law restricts radar detector use in commercial motor vehicles under specified conditions. The federal regulation defines covered vehicles by weight and operation, so commercial drivers should check 49 CFR § 392.71 and applicable employer rules rather than relying on the general passenger-car summary.
Read the manufacturer’s description to establish whether the equipment only receives signals or also transmits or interferes. A combined system can include separate components with different legal treatment; identify each component before installation.
Laws can change and federal restrictions may apply even where a state rule is narrower. Review the current Texas statute and federal regulation, and seek advice from a qualified attorney if your vehicle or equipment falls into a special category.
Common questions
Texas Transportation Code § 547.616 prohibits radar interference devices; it does not state a general ban on ordinary receive-only detectors. Other rules may apply to a specific vehicle or equipment configuration.
No. Texas law prohibits using, attempting to use, installing or operating a radar interference device in a motor vehicle, subject to the statutory law-enforcement exception.
Federal regulation restricts their use in certain commercial motor vehicles. Check 49 CFR § 392.71 against the vehicle’s weight and operation.
The Texas definition of a radar interference device includes equipment intended to disrupt radar or laser speed-measuring devices. A warning-only detector is a different function; verify the exact product configuration.
