MN HF2973

Authorizes local authorities to regulate traffic at intersections using traffic safety cameras as an alternative to police officers and traffic-control signals.

Defines "traffic safety camera" as a remotely operated recording device capable of recording clear images of both vehicle movement at an intersection and the driver of the vehicle.

Requires government entities using traffic safety cameras to post signage within 500 feet of each regulated intersection notifying drivers of camera presence.

Establishes violations detected by traffic safety cameras as petty misdemeanors and allows citations to be issued by mail.

Restricts retention of data collected by traffic safety cameras to 30 days after final adjudication and all appeals, with private contractors limited to 30 days or 180 days from violation date, whichever is shorter; all fines collected must be credited to the local authority's general revenue fund.
