What must an officer document after issuing a radar-based citation?

When an officer issues a radar-based citation, it is essential to document the radar's calibration status and the conditions during the measurement because this documentation provides critical evidence that the radar reading was accurate and reliable at the time of enforcement. Calibration ensures that the equipment is functioning correctly according to standards, and the conditions during measurement—such as weather, traffic conditions, and the distance from the vehicle—can impact the accuracy of the radar readings. Documenting these aspects demonstrates due diligence and supports the credibility of the evidence if the citation is challenged in court. It shows that the officer followed proper procedures and that the radar was in proper working order, which is crucial for upholding the citation's validity.
