Arizona Registration Requirements

High Occupancy Vehicle (HOV) Lane Exemption

Contingent upon approval from the federal government, qualified low-emission and energy-efficient vehicles are permitted to use HOV lanes, regardless of the number of passengers. Qualified vehicles must meet specified fuel economy requirements and are required to display the low-emission and energy-efficient vehicle license plate. However, use of HOV lanes may be restricted if certain traffic volume and speed criteria are not met. A low-emission and energy-efficient vehicle is defined as a vehicle that has been certified by the U.S. Environmental Protection Agency in accordance with U.S. Code Section 166, or that is part of a federally approved pilot program. (Reference Senate Bill 1320, 2009, and Arizona Revised Statutes 28-337 and 28-2416)

Alternative Fuel Vehicle (AFV) License Tax

The initial annual vehicle license tax on an AFV is lower than the license tax on conventional vehicles. The vehicle license tax on an AFV is $4 for every $100 in assessed value. The assessed value of the AFV is determined as follows: during the first year after initial registration, the value of the AFV is 1% of the manufacturer's base retail price (as compared to 60% for conventional vehicles); during each succeeding year, the value of the AFV is reduced by 15%. The minimum amount of the license tax is $5 per year for each motor vehicle subject to the tax. (Reference Arizona Revised Statutes 28-5805 and 28-5801)

Electric Vehicle (EV) Parking

An individual is not allowed to stop, stand, or park a motor vehicle within any parking space specially designated for parking and recharging EVs unless the motor vehicle is an EV and has been issued an alternative fuel vehicle special plate or sticker. A person who is found responsible for a violation may be subject to a civil penalty of at least $350. (Reference Arizona Revised Statutes 28-876)

Alternative Fuel Vehicle (AFV) Special License Plate

AFVs must display an AFV license plate. State or agency directors who conduct activities of a confidential nature and have a vehicle powered by an alternative fuel are exempt from the requirement of displaying an AFV special license plate. The Arizona Department of Transportation has the authority to issue regular plates to AFVs that are used by law enforcement and the federal government. (Reference Arizona Revised Statutes 28-2511 and 38-538.03B)

Liquefied Petroleum Gas (LPG) and Compressed Natural Gas (CNG) Device Fee

The Arizona Department of Weights and Measures collects license fees for LPG motor fuel measuring and CNG fueling devices used for commercial purposes. A penalty equal to 20% of the fee may be imposed for late license fee payments. (Reference Arizona Revised Statutes 41-2092)

Biodiesel Blend Labeling Requirement

Motor fuel dispensers used to dispense biodiesel blends of up to 5% must be labeled to indicate that the fuel dispensed may contain up to 5% biodiesel. (Reference House Bill 2330, 2009, and Arizona Revised Statutes 41-2083)
