Red and Green Stickers

California Air Resources Board (ARB) established regulations to limit the use of Off-Highway Vehicles (OHVs) that do not meet emission standards applicable for California OHV riding areas. After the regulations were established, ARB and DMV worked together to develop criteria for identifying non-complying OHVs. OHVs are registered by the Department of Motor Vehicles (DMV). A red or green sticker is issued depending upon certain criteria.

Green stickers are issued for all California OHVs year model 2002 and older, including those that were previously issued a red sticker, and to 2003 and newer complying vehicles. Green stickers are issued to OHVs for year round use at all California OHV riding areas.

Red stickers are issued to 2003 year model and newer OHVs that are not certified to California OHV emission standards. If your OHV has a "3" or "C" in the eighth position of the vehicle identification number (VIN) then your vehicle will be issued a red sticker. Red stickers are issued to OHVs that can use California OHV riding areas for seasonal use only.
