railroad grade crossing; on-track equipment..

HB 2259 amends Arizona's railroad crossing safety laws to clarify when drivers must stop and how they must proceed. It requires all drivers approaching a crossing to stop 15-50 feet from the tracks if signals are active, gates are down, trains are visible, or conditions are hazardous. Specific rules apply to commercial vehicles (must ensure space on the other side), school buses (must follow district policy), and heavy equipment (must notify railroads and confirm safety before crossing). The bill also prohibits U-turns on tracks, proceeding around gates, and pedestrians lingering in active crossing zones. These changes directly affect all drivers, commercial operators, and heavy equipment users at railroad grade crossings statewide.
