AZ HB2232

Amends Arizona Revised Statutes sections 28-851, 28-853, and 28-854 to include references to "on-track equipment" alongside trains at railroad grade crossings.

Requires drivers to stop and observe safety procedures when encountering signals, gates, or approaching on-track equipment, expanding the definition of hazards beyond just trains.

Clarifies that operators of vehicles carrying passengers for hire, school buses, and vehicles carrying explosives or flammable liquids must listen and look for both trains and other on-track equipment before crossing.

Updates requirements for heavy equipment operators to give notice to railroad station agents and check for approaching trains or other on-track equipment before crossing.

Applies safety protocols to all on-track equipment rather than restricting them to traditional railroad trains.
