Police officers use various tools to detect speed, including radar guns, lidar (light detection and ranging), and pacing methods. Radar guns emit radio waves that measure the speed of moving vehicles, while lidar uses laser beams for more precise speed readings. Some officers may also use pacing, where they match their speed to that of the suspected speeding vehicle. These technologies help ensure enforcement of speed limits for safety on the roads.
