Relating to the use of automated traffic control systems by local authorities and law enforcement agencies.

HB 3309 restricts local authorities and law enforcement from using automated speed cameras (like photo radar) to enforce speed limits on most roads, except in construction or maintenance work zones. It requires agencies to delete non-relevant data promptly and mandates clear signs at least 100 feet before work zones, plus officer presence when issuing citations. The bill directly affects municipalities and police departments that operate traffic enforcement systems. Key changes include banning general use of automated speed enforcement while creating specific rules for work zone safety, ensuring citations can only be issued if officers are present and signs meet clear standards.
