Have you ever been caught by radar and then nailed with a speeding ticket? One time is usually enough for people to always want to avoid this from happening in the future. A radar detector is an accessory you can purchase for your vehicle that detects the use of nearby radar.

Keep the radar detector in your car to give you warning about the use of a speed radar gun. The accessory gives you enough warning that you are able to reduce your speed, and avoid getting a ticket. The way it works is that an alarm usually goes off, so you don't have to keep your eye on the radar detector. It can just be mounted on the front dash of your vehicle.

Here are a few important things to keep in mind regarding radar detectors:

  • Detector options: Some of the options include a cordless or corded radar detector, laser detection, a "city mode" which will decrease the sensitivity of the unit, voice alerts, and more.

  • Read the packaging: Keep in mind that the handheld radar guns used by police officers have come a long way, and are constantly trying to find ways to go undetected. In addition, they are finding ways to give less of a warning, so you may not be able to slow down as fast. This is why it’s very important to read the packaging well, so you’re well aware of the distance it can detect it from, and what kind of radar detecting technology it uses.

  • Legality: There is some discussion as to whether the radar detectors are legal. In the United States, they are permitted for use in passenger vehicles in all states except the state of Virginia and the District of Columbia (Washington DC).

A radar detector alerts you to the use of a handheld radar gun nearby so you have the opportunity to slow down, and not be caught speeding.
