Some of these factors that would affect whether or not a radar detector is legal to include military bases, commercial vehicles, and windshield mounting. Read on to know more details about these factors.

This is especially because the two devices are often used together to have security from speeding tickets. A radar jammer is a device designed to interfere with the police radars and prevent them from detecting your current speed.
So, is it illegal to have a radar detector and a radar jammer at the same time?
