Radar Detector (RD)
A device that alerts the user to the presence of radar in the area. It alerts to not only police vehicles transmitting radar in the moment, but also other sources of radar such as automatic door openers, speed signs, and even certain vehicle’s blind spot sensors. It provides the user additional situation awareness regarding their environment.
Some detectors have additional features that alert to the presence of laser, RedLight cameras, and known speed traps.
