Section 26 of 38
Chapter 25: Permits and Decals
25.005 Sunset of the Clean Air Vehicles Decal (CAVD) Program (VC §§5205.5 and 21655.9)
The Clean Air Vehicle Decal (CAVD) Program ends at midnight on September 30, 2025. Beginning October 1, 2025, all CAVDs will expire. All decal holders must meet the posted vehicle occupancy requirements for traveling in a carpool/High-Occupancy Vehicle (HOV) lane and pay the required tolls or risk a citation.
Important dates:
- August 1, 2025: The payment turnaround time for the CAVD online application was shortened from 10 days to 2 days. This was done to ensure that customers receive a CAVD that has not yet expired.
- August 29, 2025, at 5:00 PM: The CAVD online application is no longer available. This ensures the Department of Motor Vehicles (DMV) does not receive and process any CAVD applications or mail a CAVD that would expire within days of receipt by the customer.
Note Any paper applications received after this date, including incomplete CAVD applications being returned to DMV, will be returned to the customer unprocessed. - September 2025: DMV, in collaboration with the California State Transportation Agency (CalSTA), will issue a notice to remind CAV decal holders about the program ending.
- September 30, 2025: The CAVD Program ends at midnight.
FAQs
Q. Why is the CAVD Program ending?
A. The federal government is ending the CAVD Program at midnight on September 30, 2025, pursuant to Section 166 of Title 23 of the United States (U.S.) Code. While the federal government gives DMV the authority to create the CAVD Program, the state must follow federal regulations which are expiring.
Q. Why is the CAVD Program ending when CA law was changed to extend the program to January 2027?
A. California changed the law in hopes that the federal government would extend the CAVD Program. However, that federal authority was not extended, so the program ends at midnight on September 30, 2025.
