Off-roading in California
This article is a travel topic
There are many off-road vehicle opportunities in California, but first you must make sure that your vehicle is registered. All vehicles operated on public lands in California must be registered, either with a street-legal registration or a off-highway vehicle registration. Registered off-highway vehicles receive either a red sticker or a green sticker, with red sticker vehicles only allowed to operate October 1 to May 31.
Many dirt roads are open to registered OHVs, but there are a few exceptions. For example, dirt roads in Death Valley National Park are open only to street-legal vehicles. Also, in many National Forests, some "maintained" dirt roads require street-legal registration and a license. Always check before-hand.
Helmets, of course, are required, and other safety equipment, such as proper clothing, boots, and sunglasses are recommended.
- Open Areas are open to all vehicle travel, including cross-country travel.
- Limited Use Areas are a gray area as the term is somewhat ambiguous. Occasionally travel on all existing, well-defined roads is allowed, but many times travel is restricted to only signed, marked routes. If it is the latter, be very cautious or you could find yourself with a ticket.
- Wildernesses do not allow motorized travel. In many instances, such as National Forest wildernesses, all mechanized (i.e. bicycles and motor vehicles) are prohibited.
