What equipment is necessary for the speedometer test on moving radars?

For conducting a speedometer test on moving radars, a certified speedometer is essential. This equipment is crucial because it provides an accurate measurement of the vehicle's speed. The speedometer must be certified to ensure that it adheres to the standards of accuracy required for law enforcement purposes. This allows officers to verify that the radar readings are consistent with the vehicle's actual speed.

Using a certified speedometer allows law enforcement personnel to confirm the calibration and functionality of the radar, enhancing the reliability of the speed measurement captured by the radar unit. The results from the speedometer test can then be compared against the radar readings to assess the radar’s accuracy and ensure that it is performing effectively.
