Clean Air Vehicle Decals

If you have paper or temporary license plates, please wait until you receive your permanent license plates before applying for a CAV decal.

Only the vehicle’s registered owner can apply for a Clean Air Vehicle (CAV) decal.

Already applied? You can check the status of your application.

Some vehicles that meet certain emissions standards may be eligible for a CAV decal and identification card. These allow use of High Occupancy Vehicle (HOV, or carpool) lanes.

Before you begin…

1. The application will check eligibility.
2. If your current mailing address does not match the address on your vehicle registration, update your address (allow three days for processing).
3. Be prepared to pay the $22 CAV decal fee.
   • All credit/debit card transactions include an additional 1.95% payment processing fee.
   • There are no additional fees if paying directly from your bank account.

When applying, ensure you enter your name exactly as it appears on your registration card.
