Police officers catch people speeding every day. In Arizona, the most popular way to catch someone speeding is by using a radar gun. If you’re blatantly traveling at high speeds, an officer can also stop you for reckless driving, even if he or she did not clock you.

In addition, officers can time you from one point to another, so if you go through a tollbooth at one time, speed, and then go through a second tollbooth, they can calculate that you were speeding. However, that is rare – most commonly, radar guns are used to catch people speeding. Keep in mind that a police officer can pull over multiple cars at once, just by clocking the lead car. So, if you are behind a car that is speeding and are keeping up with that car, the police officer can cite you for speeding as well, even if he or she did not clock you.
