Is a Radar Detector Legal in Florida?
For ordinary passenger cars, Florida does not appear to have a general detector ban. Federal rules prohibit detectors in commercial motor vehicles, and other states may restrict them.
Commercial motor vehicles follow federal rules
Under 49 CFR ? 392.71, a driver may not use a detector in a commercial motor vehicle or operate one containing it.
A detector is not a jammer
A detector receives signals; a jammer seeks to interfere with speed measurement. Do not treat information about detectors as permission to use an interference device.
Check the whole route
If your trip crosses state lines, review each state?s current rule. Virginia prohibits detector-equipped vehicles on its highways, with statutory exceptions.
