The Arizona Department of Transportation (ADOT) allows qualified alternative fuel vehicles (AFV) with an AFV license plate to use HOV lanes, regardless of the number of occupants. Qualified AFVs are defined as vehicles powered exclusively by electricity, propane, natural gas, hydrogen, or a blend of hydrogen with propane or natural gas. Qualified AFVs must not be capable of operating on any other fuel type. This exemption expires September 20, 2025. For more information about vehicle eligibility and HOV access, visit the ADOT AFV website. (Reference Arizona Revised Statutes 1-215 and 28-2416)
