Overview

• California DMV and CARB confirmed that the Clean Air Vehicle Decal program will expire at midnight on Sept. 30 and that the last day to apply is Aug. 29.
• Starting Oct. 1, decal holders will lose solo access to HOV lanes and must meet posted occupancy requirements or pay standard tolls and face fines for violations.
• State officials had approved an extension through January 2027, but federal authorization under transportation statutes was not renewed by the EPA.
• Since its 2001 launch, the program awarded decals to over one million low- and zero-emission vehicles as a key incentive for electric vehicle adoption.
• Supporters warn ending the decals could slow EV uptake, while critics say it will restore carpool lane priorities, reduce congestion and address enforcement gaps.
