         144.6(3) Enforcement.

         144.6(4) Calibration. Automated traffic enforcement systems require periodic calibration to ensure accuracy and reliability. Calibration shall be conducted by a local law enforcement officer, trained in the use and calibration of the system, at least quarterly for fixed systems and prior to being used at any new location for mobile systems.
