This bill proposes updates to section 28-737 of the Arizona Revised Statutes concerning high occupancy vehicle lanes. The new language specifies that vehicles towing a trailer, semitrailer, or pole trailer are prohibited from using high occupancy vehicle lanes at any time. Additionally, the bill clarifies that the definition of an authorized emergency vehicle is applicable only to those in use by a first responder in the line of duty, removing the previous reference to the definition in section 28-101.

Furthermore, the bill maintains the existing civil penalty for violations of high occupancy vehicle lane restrictions at $200, while also ensuring that $100 of each civil penalty collected is deposited into the state general fund. Overall, the bill updates the statute to enhance clarity regarding vehicle usage in high occupancy lanes and maintains the financial provisions related to penalties.
