Three Ways a Police Officer May Check Your Speed

As you are driving along I-64 in Norfolk, minding your own business, you see a police cruiser in your rearview mirror.  As the police car gets closer, the sirens come on and the officer pulls you over and issues you a speeding citation.

If you are like most people, you are upset, frustrated, and angry. The expenses related to a speeding ticket are significant—fines, points on your license, and insurance rate increases. However, you can fight a speeding ticket and win.

One of the common ways to fight a speeding citation is to fight against the tools the police officer used to determine your speed. Most likely, the officer used one of the following methods to clock your speed:

  • Radar gun – This gun, which takes advantage of the Doppler Effect, may be handheld or mounted on the vehicle. It measures speed by sending out a radio pulse and then waiting for the signal to return. It then measures the change in frequency of the signal to determine speed.
  • LiDAR speed gun – LiDAR stands for light detection and ranging, a method of speed detection that measures the time for a pulse of laser light to reach a moving object and reflect back. LiDAR speed guns have become popular with police because they can be used to target a specific vehicle in traffic.
  • Pace clocking – Pace clocking is a method used by police to monitor the speed of another vehicle while his cruiser is in motion. The officer remains a set distance from the vehicle he is clocking and checks the speed using his own speedometer. While commonly used, it can be inaccurate if not properly executed.
