What should first responders do if a RADAR unit fails during a stop?

When a RADAR unit fails during a stop, the appropriate action for first responders is to document the failure and switch to alternative enforcement methods, such as visual pacing. This approach ensures that the officer maintains the integrity of the enforcement process and complies with legal and procedural standards.

Documenting the failure creates a record that can be important if questions arise regarding the enforcement action taken, helping to protect the officer and the department from potential liability. Switching to alternative methods like visual pacing enables the officer to still address the violation safely and effectively without reliance on the non-functioning equipment, ensuring that enforcement is still carried out in a fair manner.

In comparison to other options, immediately calling for technical support may not be practical in the heat of the moment, and attempting to repair the unit on the spot can divert attention from the ongoing situation, possibly compromising safety. Continuing to use the RADAR unit without modifications after knowing it has failed is not advisable, as it undermines the validity of the enforcement and could lead to challenges in court.
