Clean Air Vehicle (CAV) Decals - High Occupancy Vehicle (HOV) Lane Usage
Note: Beginning January 1, 2019, Assembly Bill 544 creates a new decal program to allow certain low emission vehicles to access high-occupancy vehicle lanes, regardless of vehicle occupancy level, for a four-year term. Access to high-occupancy vehicle lanes for vehicles with green and white decals will expire January 1, 2019. Vehicles issued a green or white decal in 2017 or 2018 will be eligible to reapply for a decal in 2019 granting them access to high–occupancy toll lanes until January 1, 2022.
A vehicle that meets specified emissions standards may be issued CAV decals that allow the vehicle to be operated by a single occupant in highway lanes designated for High Occupancy Vehicles (HOV). See California Vehicle Code (CVC) §§5205.5 and 21655.9.
The fee for a clean air vehicle decal is $22.
Effective January 1, 2018, the Department of Motor Vehicles cannot issue a CAV decal to an applicant who has received a consumer rebate through the Clean Vehicle Rebate Project (CVRP), nor can an applicant participate in both the CAV Decal Program and the CVRP unless income restrictions are met. (See Question #6 in the FAQs.)
For additional information, visit the California Air Resources Board's (ARB) website at www.arb.ca.gov.
To ensure your CAV decal application is complete, please refer to question #4 in the FAQs before submitting your application.
White CAV Decals
White CAV decals are issued according to the following criteria:
- A vehicle that meets California's super ultra-low emission vehicle (SULEV) standard for exhaust emissions and the federal inherently low-emission vehicle (ILEV) evaporative emission standard. This includes certain zero-emission vehicles (ZEVs). Vehicles that meet these requirements are certified pure zero emission vehicles (100% battery electric and hydrogen fuel cell). Liquefied petroleum gas (LPG) and compressed natural gas (CNG) fueled vehicles also qualify for white CAV decals.
- A 2004 model-year or older vehicle that meets the California ultra-low emission vehicle (ULEV) standard for exhaust emissions and the federal ILEV standard.
Green CAV Decals
Green CAV decals are issued to vehicles that meet California’s Enhanced Advanced Technology Partial Zero-Emissions (Enhanced AT PZEV) or Transitional Zero-Emission (TZEV) standards for exhaust emissions. Vehicles that meet these requirements are usually plug-in Hybrids.
Yellow CAV Decals (Program ended 7/1/11)
The Hybrid CAV decal program ended on July 1, 2011. Owners of hybrid CAV displaying yellow CAV decals are no longer allowed to operate their vehicle in a HOV lane unless the minimum passenger requirements are met. After July 1, 2011, use of an HOV lane, without the minimum required passengers, may subject the driver to citation. These vehicles do not qualify for any other type of decals.
All CAV decals
State law extends the use of CAV decals for SULEV, ILEV, and certain ULEV vehicles (white) and enhanced AT PZEV or TZEV (green) through January 1, 2019. All CAV decals must also be reauthorized for use by the Federal Highway Administration. If reauthorization is not granted, the Clean Air Vehicle decal program may end sooner than state law currently allows.
- Carpool lane use may be restricted at any time by the California Department of Transportation and federal law for all CAVs carrying fewer occupants than the posted minimum requirement, if their presence contributes to increased traffic congestion, increased travel times, decreased sustained travel speeds, or other factors affecting any carpool lane or segment of that lane.
- CAVs that meet the posted minimum occupancy requirements for carpool lanes are not subject to the above restrictions.
- All CAV decals remain with the vehicle they were originally issued to and cannot be transferred to any other vehicle. If you purchase a vehicle that has CAV decals, you may transfer the decal to your name. Refer to the following frequently asked questions (FAQs).

Replacement CAV Decals
A: To apply for replacement CAV decals or ID card:
- Complete an Application for Clean Air Vehicle Decal (REG 1000) PDF form.
- Check the "Replacement Decals" box and the box for the appropriate reason for replacement or check the "Replacement ID Card Only" box in Section 2 of the REG 1000.
- Check the Replacement box in Section 2, check the appropriate box for the reason a replacement is being requested and provide the previous decal number:
- Stolen – If the CAV decals were stolen off the vehicle, you can find the decal number on the CAD Certificate and/or the new Registration card that was sent with the decal for the decal number.
- Lost or Damaged – If the decals were lost or damaged (this includes if the vehicle was repainted with the decals still on the vehicle), please refer to the CAD Certificate and/or the new registration card that was sent with the decal for the decal number.
- Not Received – You are not expected to know the decal number if the decals were not received from the department or the previous vehicle owner. Replacement CAV decals will not be issued within 30 days of the most recent decal issuance, to allow sufficient time for mailing.
17. Q: I only need one replacement CAV decal; will DMV just send one replacement CAV decal with the same number?
A: No. The new set of CAV decals must be placed on your vehicle following decal placement instructions. It may be necessary to remove all remaining CAV decals.
18. Q: Do I have to surrender the remaining CAV decals?
19. Q: Does DMV cancel the original CAV decal number when replacements are issued?
A: Yes. The previously issued CAV decal number is cancelled and no longer valid.
20. Q: What should I do if the original CAV decal was received or found after it was replaced and cancelled?
A: All sets of the previously issued CAV decals must be surrendered with a letter of explanation (e.g., you requested a new set of CAV decals, received them, and the missing original CAV decals were found later) to DMV (see the REG 1000 (PDF) form for the address) if they were received or found after being replaced and cancelled. The newest set of decals you were issued are valid. To avoid a citation, verify the CAV decal number with the CAV decal ID card to ensure it matches the actual CAV decal number on the vehicle.
Vehicle Does Not Qualify
21. Q: My vehicle does not qualify for CAV decals, does DMV approve "hardship" requests?
A: No. The DMV is not authorized to approve "hardship" requests. They can only issue CAV decals to eligible vehicles as determined by the ARB.
22. Q: My vehicle was eligible and issued clean air decals prior to January 1, 2017; can I apply for new decals after January 1, 2019, when my white or green decal expires?
A: No. Under the new CAV program, vehicles that were issued CAV decals prior to January 1, 2017, are no longer eligible to receive new decals after January 1, 2019, (California Vehicle Code 5205.5).
CAV Decal Placement
23. Q: Where do I place the CAV decals on the vehicle?
A: CAV decal placement:
Carefully peel CAV decals from the backing material and apply as follows:
1. Large Decals-
- Place on the rear quarter panels, one on each side of the vehicle, behind the wheel wells, with the state seal pointed up on the bottom of the decal.
2. Small Decals-
- For white decals, place on the right side of the rear bumper only, with the state seal pointed up on the bottom of the decal.
- For green decals, place on the right side of each bumper, front and rear, with the state seal pointed up on the bottom of the decal.
Do not attempt to remove or reposition CAV decals after application. Doing so will result in the destruction of the decals.
After Receiving CAV Decals
24. Q: My name is misspelled on my CAV decal ID card Do I need to notify DMV to obtain an updated CAV decal ID card?
A: Yes. You have to notify DMV if the information on the CAV decal ID card needs to be corrected by completing a REG 1000 (PDF) form and check the “Information correction/update” box in Section 2. There is no fee required for corrections or updates and you will receive a new CAV decal ID card within 30 business days.
25. Q: I have a new address or a new license plate number. Does changing the information on my vehicle registration also update information for my CAV decal record?
A: No. The process of changing the address for your decal record is a separate process. You need to complete a REG 1000 (PDF) form and check the “Information correction/update” box in Section 2. There is no fee required for corrections or updates. You will receive a new CAV ID card within 30 business days.
26. Q: If I am stopped by law enforcement, what documentation do I need to show the officer for my CAV decals?
A: You must present your current registration card and your CAV decal ID card.
27. Q: Can I affix the CAV decals to another vehicle?
A: No. All CAV decals remain with the vehicle they were originally issued to and cannot be transferred to any other vehicle.
