What constitutes proper evidentiary support for RADAR-based tickets?

Proper evidentiary support for RADAR-based tickets is fundamentally rooted in the accuracy and reliability of the equipment used, as well as the competence of the operator. Accurate device calibration and operator training records are essential components that ensure the integrity of data collected by RADAR devices. These records demonstrate that the RADAR unit has been properly calibrated according to manufacturer specifications and legal standards, which is vital for confirming that the readings are reliable and valid in a court of law.

Operator training records indicate that the person operating the RADAR has received the necessary instruction and knowledge to use the device correctly. This means they are able to interpret the readings accurately and understand the operational principles behind the technology. Both factors contribute to the establishment of credibility when tickets are challenged in legal settings.

In contrast, random checks without documentation do not provide the necessary support, as there's no proof that the checks were performed consistently or correctly. Witness statements alone may lack the objective evidence needed to substantiate a speeding violation, and issuing tickets without adherence to city policies undermines the legal basis on which these tickets are issued and processed. Thus, having documentation of calibration and operator training is crucial for sustaining the evidentiary support required for RADAR-enforced speeding tickets.
