When is it essential to perform an accuracy check on RADAR equipment?

Performing an accuracy check on RADAR equipment is essential when requested because it ensures that the equipment is operating correctly and providing accurate measurements. The request for an accuracy check can come from various sources such as departmental policy, disputes regarding a citation, or a routine inspection. This practice is vital in maintaining the reliability of speed measurements and ensuring that the information obtained can stand up to scrutiny in a legal context.

Regularly conducting accuracy checks upon request upholds the standards necessary for precision in speed enforcement and builds confidence in the enforcement process. It's important to note that while routine checks at specific intervals are beneficial and may be part of the agency’s policies, they may not be mandated as frequently as some other options suggest. Thus, the flexibility of responding to requests provides a practical approach to maintaining RADAR efficacy.
