The proposed bill would update current statutes related to commercial motor vehicles by introducing new definitions and modifying existing ones, particularly concerning vehicle weight classifications. It would replace the term "gross vehicle weight" with "DECLARED gross weight as defined in section 28-5431" and clarify that vehicles must meet specific weight criteria for intrastate commerce. Additionally, the design capacity for vehicles transporting passengers for hire would be increased from eight to nine persons. The definition of "hazardous substance" would also be amended for grammatical accuracy.

In terms of penalties, the bill would lower various violations from misdemeanors to civil penalties, such as reducing the penalty for operating a vehicle in violation of an envelope permit from a class 1 misdemeanor to a civil penalty of $750, and changing another violation from a class 2 misdemeanor to a civil penalty of $500. These changes aim to streamline regulations, reduce legal burdens on commercial vehicle operators, and enhance safety compliance on Arizona's roads.
