Clean Air Stickers - High Occupancy Vehicle Lane Usage

A vehicle that meets specified emissions standards may be issued Clean Air Vehicle Stickers that allow the vehicle to be operated by a single occupant in the High Occupancy Vehicle (carpool or diamond) lanes of California's freeways. See Vehicle Code (VC) §§5205.5 and 21655.9.

White or yellow Clean Air Stickers are issued according to the following criteria:

White Clear Air Sticker

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.

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.

Yellow Clean Air Sticker

A hybrid or alternative fuel vehicle that meets California's advanced technology partial zero-emission vehicle (AT PZEV) standard for criteria pollutant emissions and has a 45 miles per gallon or greater fuel economy highway rating.

A 2004 model-year or older hybrid vehicle that has a 45 mile per gallon or greater fuel economy highway rating and meets California's ultra-low emission vehicle (ULEV), super ultra-low emission vehicle (SULEV), or partial zero-emission vehicle (PZEV) standards.

The 85,000 Clean Air Vehicle Stickers (yellow) that VC 5205.5 allows for hybrid vehicles have been assigned. Original Clean Air Stickers will no longer be issued to hybrids; however, substitute stickers may be issued if the original is damaged.


To find out if your vehicle qualifies, check the California Air Resources Board (ARB) website.

PLEASE NOTE:

  • Effective January 1, 2009, DMV may issue new Clean Air Stickers to ORIGINAL owners of qualifying hybrids purchased to replace hybrids that have been subsequently declared total/loss salvage. Applications for replacement must be filed within six months of the date of total loss/salvage.
    Applicants previously denied decals for a replacement vehicle may reapply and have their applications accepted through March 31, 2009.
  • All Clean Air Stickers remain with the vehicle they were originally issued to and cannot be transferred to any other vehicle. If you purchase a vehicle that has a Clean Air Sticker you may transfer the sticker to your name.
  • If you acquire a hybrid vehicle with Clean Air Vehicle Stickers attached, and are a resident of Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano or Sonoma County, you must obtain a Bay Area FasTrak account before you drive as a sole occupant in a high-occupancy vehicle (carpool or diamond) lane.
  • All Clean Air Vehicle stickers will expire January 1, 2011, unless the law authorizing their use is extended beyond that date.
  • Carpool lane use may be restricted at any time by state and federal law for all Clean Air Vehicles carrying fewer occupants than the posted minimum requirement, if their presence is determined by the California Department of Transportation to contribute to increased traffic congestion, increased travel times, decreased sustained travel speeds, or other factors affecting any carpool lane or segment of that lane.
  • Clean air vehicles that meet the posted minimum occupancy requirements for carpool lanes are not subject to the above restrictions.

Transferring Clean Air Vehicle Stickers to Your Name

  1. Complete an Application for Clean Air Vehicle Stickers (REG 1000).

If the clean air vehicle is a hybrid and you are a resident of Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano or Sonoma County, you must include an original Bay Area FasTrak receipt as evidence of a "FasTrak" toll account. The FasTrak receipt must show evidence that a toll account was issued specifically to your hybrid vehicle. Do not submit evidence of pre-existing FasTrak accounts for other vehicles, as this will delay your application. Bay area applicants are advised to contact Bay Area FasTrak at 877-229-8655 or visit the Bay Area FasTrak website before submitting a request to transfer Clean Air Stickers for a hybrid vehicle.
