True or False: Moving RADAR instruments measure two speeds.

The statement is true because moving radar instruments are designed to measure both the speed of the target vehicle and the speed of the radar unit itself when in motion. This dual speed measurement capability allows law enforcement officers to accurately determine how fast a vehicle is traveling relative to a stationary point or relative to the moving radar unit itself.

When the radar unit is in motion, it calculates the speed of the vehicle approaching or departing from the radar unit while simultaneously accounting for its own speed, ultimately ensuring that the speeds reported are precise. This functionality is critical for enforcing speed limits in various traffic situations and enhancing the overall accuracy of speed enforcement methods.
