What test is performed on moving radars to compare the patrol speed reading?

The appropriate test performed on moving radars to compare the patrol speed reading is the speedometer test. This test is essential for verifying the accuracy of the radar system by comparing the speed indicated by the patrol vehicle's speedometer with the speed recorded by the moving radar unit.

This process typically involves driving the patrol vehicle at a set speed and ensuring that both the speedometer and the radar display consistent readings. This verification is critical as it helps to ensure that the radar system is functioning correctly and providing accurate speed measurements for enforcement purposes.

Calibration tests and performance assessments focus on ensuring that equipment meets specific operational standards, while functional speed tests assess whether the radar operates within its designated parameters, but they do not specifically compare vehicle speed readings like the speedometer test does.
