This bill proposes updates to the vehicle registration fees outlined in section 28-2003 of the Arizona Revised Statutes. The current law specifies a flat fee of $8 for motor vehicles fueled exclusively by motor vehicle fuel or use fuel, and $9 for motorcycles. The bill introduces new fee structures for vehicles based on their fuel type, including a fee for vehicles fueled exclusively by alternative fuels, calculated as $85 multiplied by the ratio of the motor fuel tax to $0.18, and a fee for vehicles using a combination of alternative and motor vehicle fuels, set at $40 multiplied by the same ratio.

Additionally, the bill includes a provision that requires it to take effect only upon an affirmative vote of at least two-thirds of the members of each house of the legislature, and it will become effective immediately upon the governor's signature or, if vetoed, upon a subsequent affirmative vote of at least three-fourths of the members of each house. This change aims to modernize the fee structure to better reflect the diversity of vehicle fuel types in use today.
