Each local police department and State police department that deploys a work zone speed control system shall maintain a registry and files documenting the training and certification of each of its certified work zone speed control system operators. Each local police department and State police department that acquires a work zone speed control system shall: Obtain the initial and annual independent calibrations required by Transportation Article, §21-810(b)(6), Annotated Code of Maryland; and Maintain a file documenting the results of all calibration testing. A work zone speed control system may not be used for enforcement purposes unless the agency deploying the system possesses the required initial and annual certificates from an independent laboratory that certifies that the system is properly calibrated. A work zone speed control system operator shall complete the daily set-up log required by Transportation Article, §21-810(b)(5), Annotated Code of Maryland, that states: The date and time when and the location where the system was set up; and That the operator successfully performed, and the device passed, the manufacturer-specified self-tests before producing a recorded image. The set-up log and these self-testing procedures under §D of this regulation shall be completed whenever the system is relocated and following each system start-up. A work zone speed control system may not be used for enforcement unless the operator has completed all required set-up logs, the system has passed all manufacturer-specified self-tests, and the system is operating properly. A work zone speed control system may be used only to record the images of vehicles that are traveling at speeds at least 12 miles per hour above the posted speed limit in the work zone.
