VASCAR (Visual Average Speed Computer and Recorder) is a device used by law enforcement to measure the speed of vehicles. However, there are several other words that can be used to refer to this type of equipment. One synonym for VASCAR is a speedometer, which is a gauge that measures the speed of a vehicle. Another synonym is radar, which uses radio waves to detect the speed of an object. Lidar, which stands for Light Detection and Ranging, is another device that measures speed using laser technology. No matter the synonym used, the purpose of these devices remains the same, to ensure road safety by detecting and deterring speeding drivers.
