California is expected to run out of single-occupant carpool lane stickers for drivers of zero-emission vehicles nearly five years before the program expires, the Air Resources Board has announced.

As of March 28, California has issued 38,179 green Clean Air Vehicle decals that are valid through Jan. 1, 2019. Eligible fleet vehicles can participate in the program. Under AB 266, California will issue 40,000 green stickers to the first owners or lessees of vehicles meeting the state's transitional zero emission vehicles (TZEV) requirement.

Vehicles meeting the TZEV requirement include the Cadillac ELR, Chevrolet Volt, Ford C-Max Energi, Ford Fusion Energi, Accord Plug-In Hybrid and Toyota Prius Plug-In from the 2014 model year. Eligible vehicles from the 2013 model year include the Chevrolet Volt, Ford C-Max Energi, Ford Fusion Energi, and Toyota Prius Plug-In. From the 2012 model year, eligible vehicles include the Chevrolet Volt and Toyota Prius Plug-In.

Vehicles with the green sticker can travel in the High Occupancy Vehicle (HOV) lanes with a single occupant. The Department of Motor Vehicles distributes the stickers. Also available is the white Clean Air Vehicle decal for low-emission vehicles. These vehicles typically include batter-electric, hydrogen and compressed natural gas vehicles.
