The Over-Sand Vehicle (OSV) zone at Assateague Island National Seashore contains miles of unspoiled beaches managed by the National Park Service to accommodate OSV enthusiasts and other beach goers.

OSV permits are issued for a year from the month of purchase. The permit fee ranges from $70 to $150, depending upon the type of access desired. All vehicles using the OSV zone must display a valid OSV Permit. Upon signing the registration for the OSV permit, operators accept responsibility for knowing and following all OSV regulations. Please watch our OSV video for driving tips.

At Assateague Island National Seashore we strive to provide you with a safe and enjoyable over-sand vehicle (OSV) experience. Regulations and equipment requirements are necessary for your safety and the safety of other visitors and National Park Service staff. Changing beach conditions, vehicle breakdowns, and human judgement errors may occasionally result in over-sand vehicles becoming stuck and needing assistance. In these instances, National Park Service staff can: Assist with removing sand from around the tires. Deflate tires. Use traction devices such as boards. Make a phone call on your behalf to friends/family. Provide information regarding local towing services. National Park Service staff cannot: Winch or pull the vehicles out, or recommend a towing company.
Please be prepared when using the OSV zones on Assateague Island. Carry the required safety equipment; adequate food, water and clothing; and know the park rules and regulations.

 
Motor vehicles are permitted only within established roads, parking areas and designated Over-Sand Vehicle (OSV) routes. Use of motor vehicles in designated Over-Sand Vehicle Zones is at the operator’s own risk. The following OSV Use Regulations are established to provide for enjoyment of the park and to protect the barrier island’s fragile resources. Upon signing the OSV Permit application, permitee accepts responsibility to know and follow all OSV regulations. Failure to comply with the terms of the Permit, including these regulations, may result in revocation of a valid OSV permit and/or federal prosecution. All applicable State and Federal laws will be enforced. Violations should be reported to Law Enforcement by calling 911. Please contact appropriate Seashore or Refuge personnel with any questions.

NOTE: Permit stickers are NOT refundable or replaceable if lost.

Permit replacement: OSV permits and stickers are issued to individual permit holders for the specific vehicle designated on the permit application and MAY NOT be transferred from one person to another or from one vehicle to another.

Tips For OSV Operation:
• Remember, you are responsible for knowing the OSV rules and regulations.
• Lower tire pressure to between 15 and 20 pounds.
• Carry 4 boards (2”x 6”x 36”) for placement under each tire when stuck.
• After stopping vehicle back up several feet before proceeding forward.
• Walk across suspected soft sand first to be sure it
will hold your vehicle.
• Spinning a vehicle’s tires only makes them dig deeper into the sand thereby increasing the chance the vehicle’s frame will bottom out.
• Driving in the tracks of another vehicle is easier than driving through fresh sand.
• Carry water displacement spray for
drying wet engine electrical parts.
• Do not drive in salt water.
