Radar, which stands for radio detecting and ranging, emits radio waves that can be bounced off cars to detect how fast they’re moving. Because of this, it can target an individual vehicle and that vehicle’s speed. The beam, or cone, of light gets wider the further away you hold the flashlight from the wall.Ī laser speed gun, like a laser pointer, emits a very small beam of infrared light, even from 1,000 feet away. This is like a flashlight appearing against a wall. The size of the cone changes depending on how close or far away the target is. Radar waves are emitted in a cone-shaped beam, capturing whatever vehicles fall in that wide path. Radar, the traditional form of speed measurement, uses radio waves while laser uses, well, laser. Radar and laser speed detectors meet the same goal in different ways. It also doesn’t hurt to learn about the new features available in radar and laser technology to make the job easier on you. To bust speeders you need to know the capabilities of the speed detector you’re using and the proper way to operate it. The best part is many of these innovations have reduced the number of court dates for cops because the resulting evidence is so ironclad. Some motorists even pay hundreds of dollars on radar detectors to evade these powerful police “weapons.” But new technology in radar and lidar makes it even more difficult for drivers to beat speeding tickets. Radar guns and their laser counterparts are the bane of speeders’ existence.
