Which of the following statements about RADAR calibration is true?

Calibration of RADAR equipment is essential for ensuring accurate speed measurements. The statement regarding calibration being required annually is accurate as it establishes a clear schedule for maintenance checks that help to confirm that the device is providing reliable and precise readings consistent with legal standards. Regular annual calibration helps to account for any potential drift in the instrument's accuracy over time, ensuring that law enforcement can rely on the data collected during speed enforcement operations.

In practice, while other frequencies for calibration checks may be considered, adhering to annual guidelines represents a standard procedure that balances efficiency and reliability. Deploying RADAR equipment without regular calibration leaves open the possibility of inaccuracies, which can undermine enforcement activities and lead to improperly documented or contested citations.
