OHV Registration Requirements
In order to operate any type of motorized vehicle off-road on public land, you must have one of the following:
Street-Legal License Plate: If you want to operate a 4-wheel drive vehicle or dual-purpose motorcycle on-road and off-road, you must have a street-legal license plate.
The Green Sticker Or Red Sticker: If you are going to operate a motorized vehicle off-road only, you must have either a Green Sticker or a Red Sticker that has been issued by the Department of Motor Vehicles. The Green Sticker allows vehicles to operate on public land all year. The Red Sticker is for motorcycles and ATVs manufactured after January 1, 1997 that do not meet the emission standards established by the California Air Resources Board. If the vehicle has a 3 or a C in the eighth position of the Vehicle Identification Number, then it does not meet the emission standards and should be issued a Red Sticker. The Red Sticker is exactly the same as the Green Sticker except that these vehicles can only be operated during certain times of the year. To find out when you can operate your vehicle, call the specific riding area that you want to visit or you can look it up on our web site at http://ohv.parks.ca.gov/.
