How frequently must RADAR devices be calibrated?

RADAR devices must be calibrated annually to ensure their accuracy and reliability in speed detection. Regular calibration is essential because over time, various factors can affect the performance of these devices, including mechanical wear, environmental conditions, and changes in technology. By calibrating the equipment on an annual basis, operators can maintain confidence in their readings, which is crucial for law enforcement activities and ensuring fairness in traffic enforcement.

Calibration involves comparing the device's readings against a known standard and adjusting it as necessary to ensure that it provides accurate speed measurements. While some devices might require more frequent checks or maintenance depending on their usage or specific operational protocols, annual calibration is a widely accepted standard that helps maintain the integrity of speed enforcement practices.
