1. A local authority shall install a system in a manner that minimizes the effect of camera flash on drivers, if a camera flash is used.
2. An automated or remote system for traffic law enforcement must only record a photograph or video of the rear of a vehicle and the vehicle’s registration plate while the vehicle is used to commit an alleged traffic violation. A local authority shall not install a system such that the system’s camera is placed to capture the front of a motor vehicle or the face of any person in the vehicle being recorded. In accordance with section 321P.6, subsection 3, a citation issued by a system that captures the front of a motor vehicle or the face of any person in the vehicle is void and unenforceable.
3. A system must verify its internal calibrations daily, and a person trained in the calibration of the system shall conduct a monthly calibration.
4. A local authority operating a system shall maintain a monthly log detailing whether a person trained in the calibration of the system successfully performed the monthly calibrations and whether the system successfully performed the daily internal calibrations.
5. The log and documentation of the calibrations required under this section are admissible in any court proceeding relating to a violation detected by the system.
6. If a daily or monthly calibration is not successfully performed, the system shall not operate until a successful calibration is subsequently performed.
