All vehicles operated off-highway on public lands in California are required to be (1) street-licensed or (2) registered as an off-highway vehicle (OHV). Purchase of a California Nonresident permit is required:
If you are visiting California from another state and your vehicle does not have a current registration from your home state, you must purchase a California Nonresident OHV Use Permit before you recreate on public lands.
If your state of residence requires residents of California, who have valid OHV registration/identification (green or red sticker registration), to purchase a non-resident permit to recreate in your home state (see Off-Highway Vehicle Information Bulletin 21-1)
The Arizona street licensed OHVs are required to purchase a Nonresident Permit to recreate on public lands in California.
