In a similar vein, the growing popularity of radar detectors, some police departments now use secondary devices that can show them which passing vehicles have one installed.

When the MRCD or MRCT device detects an offending driver, it takes a photo of the vehicle’s license plate. The new MultaRadar CD (MRCD) and the even more recent MultaRadar CT (MRCT) radar devices function by using photo radar technology. Traditionally, the radar that officers use operates at a fixed frequency, also referred to as Continuous Wave radar. These days, police are adding new MultaRadar technologies to their traffic tracking arsenal. While virtually all detectors will alert drivers to the presence of radar sensors, police departments are always getting more sophisticated technology to defeat them.

The warning it sounds serve as an important reminder to slow down and a method for helping drivers avoid unwanted tickets and potentially pricey insurance hikes. Radar detectors alert you when a police radar gun is active on the road. Even the most careful drivers who watch their speed can miss a decreased speed limit sign or follow traffic without immediately noticing the flow’s increasing pace, particularly in today’s cars, which are quieter and more powerful than any of their predecessors. A good radar detector will help to prevent you from paying dearly for any oversights while you’re on the road. It’s no surprise that speeding violations are the most common reason for red and blue flashing lights to appear in the rear view mirror.
