There is an impending federal change to High Occupancy Vehicle (HOV) lane exemptions. HOV lane usage by alternative fuel vehicles is regulated by 23 U.S.C. 166(b).  This federal law was enacted in 2005 and includes an expiration date of September 30, 2025.

If Congress does not extend the exemption expiration date, owners of alternative fuel vehicles and vehicles with Energy Efficient plates will no longer qualify you to use HOV lanes with less than two people in the vehicle during restricted times.

Energy Efficient Plate Program Ends

Energy Efficient License Plate

Arizona's Energy Efficient Plate Program has ended. The program allowed eligible vehicles unrestricted access to the high-occupancy vehicle (HOV) lanes in Arizona.

Current holders of an energy efficient plate may continue to use that plate on a qualifying vehicle and make use of the HOV lanes. If the vehicle is sold, traded or otherwise has its title transferred to another party, the energy efficient plate is no longer valid.

The program was discontinued to comply with federal regulations regarding HOV lane usage.

This only applies to the energy efficient plate program. Alternative fuel vehicles, including those that are totally electric powered, are not affected.
