Guide
Tennessee legislative material distinguishes passive detectors from jamming devices. Check current state and federal rules for your vehicle before use.
Tennessee legislative materials distinguish passive radar detectors from devices that jam or interfere with speed-measuring equipment. The cited state act says its provisions do not apply to radar detectors; confirm the current Tennessee Code and any federal restrictions before using one.
Federal rules restrict radar detector use in commercial motor vehicles, and other jurisdictions have separate restrictions. Check both the vehicle classification and the roads on your route.
A detector receives signals and alerts the driver. A jammer is intended to interfere with measurement equipment and is treated differently under laws; do not assume rules for detectors apply to jammers.
Read current state and federal rules, including any recent amendments, and follow posted speed limits. A detector is not a defence against a citation or a substitute for safe driving.
