Learn about our park
As a County Parks requirement, all OHV users must wear a Department of Transportation (DOT) approved helmet at all times while operating the vehicle on the park premises. SCC ORD B14-45.1(b)(2) Motorcycle Park-Helmet Required.
For your safety and the safety of others, Off-Highway Vehicles must never be operated in a manner likely to endanger any person or property.
State and Federal law prohibit operating any vehicle while under the influence of alcohol or drugs. This applies equally to the operation of Off-Highway Vehicles, including those statutes prohibiting drinking while driving (CVC 23220) and drinking in a motor vehicle (CVC 23221).
Motorcycles and ATVs must meet state sound requirements.
California OHV sound regulations and enforcement are as follows:
If your off-highway vehicle was manufactured on or after January 1, 1986, it shall be limited to not more than 96 dBA, and if manufactured prior to January 1, 1986, to not more than 101 dBA.
If your competition off-highway vehicle was manufactured on or after January 1, 1998, it shall be limited to not more than 96 dBA, and if manufactured prior to January 1, 1998, to not more than 101 dBA.
See the California Noise Limits Law - AB 2274 web page containing excerpts from AB 2274 relating to OHV noise regulations effective January 1, 2003.
Respect wildlife and our trails
Off-highway vehicles must not be operated in a manner that creates off-trail damage or disturbance to soil, vegetation, or wildlife resources. Excessive OHV-related damage to forest resources could lead to temporary or permanent closures.
California OHV Registration

California residents must have a Green Sticker, Red Sticker, or current highway license plate for all motor vehicles operated on public lands. Registration Identification Certificate must be kept with the vehicle along with the Identification, Green, or Red Sticker. CVC 38085 Identification Certificate Kept with Vehicle. See the complete OHV Bulletin by clicking the following link: Red Sticker Riding Season Sunset December 31st, 2024.
Applying your registration sticker
Clean the surface thoroughly for better adhesion, and remove any old stickers. Note: once the sticker has been placed, removing the sticker will void the registration sticker and will no longer be valid (see example below). (CVC) 38090 Lost or Mutilated/illegible I.D. Plate.

A Green or Red Sticker can be applied to a fork sleeve and attached to the fork to preserve the sticker from damage. The fork sleeve with sticker MUST BE APPLIED TO FORK WITH A PIPE CLAMP to meet CVC 38170(b) Off-Highway Vehicles; I.D. Plate Display.

Newly purchased OHVs must have proof of temporary or current registration in the new owner’s name.
Nonresident permits

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). 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.

Appropriate safety gear
RIDE AT YOUR OWN RISK AND WEAR REQUIRED SAFETY EQUIPMENT
We only require an OHV rider to wear a fastened DOT-approved helmet. We recommend that each rider equip themselves with a helmet, goggles, shoulder guards, elbow pads, chest protectors, gloves, knee pads, shin guards, and riding boots.
Off-highway vehicle use may be hazardous. Protective apparel, skill levels, vehicle condition, terrain, weather, common sense, and following the park rules all affect your safety.

Trail markings
All trails are one-way. Proper direction of travel and trail difficulty will be indicated on carsonite posts and will appear as follows:

Electric off-road bikes
Electric off-road bikes with foot pegs are allowed at Metcalf Motorcycle Park. Electric off-road bikes with pedals are not permitted at the park.
Electric off-road bikes are like dirt bikes and ATVs and must be registered with the DMV to ride at OHV Parks. Some brands of electric off-road bikes only come with a 15-digit serial number and may require a 17-digit VIN (Vehicle Identification Number) to be assigned by the California Highway Patrol. Contact the California Highway Patrol for further information or to make an appointment.
Moped plates are not vehicle registration fees for electric off-road bikes, however dual registration can be obtained. See the DMV website for specific registration requirements.
Learn about motorcycles, mopeds, and scooters on the California DMV site.
