The following is a basic summary of the rules and regulations as of summer 2012 for taking your vehicle on the shores of Assateague Island. If you plan to take your vehicle off-road on Assateague Island it is best to check with the National Park Service, as some of these rules are subject to change.

The top of the form states, "The following regulations apply to Over-Sand Vehicle (OSV) use. Regulations are established to provide enjoyment of the park while protecting the fragile resources of this barrier island. Upon signing the application for the OSV permit, operators accept responsibility for knowing and following all OSV regulations. Failure to comply with these terms may result in revocation of OSV permit and/or Federal prosecution. Motor vehicles are permitted only on established roads, parking areas, and designated over-sand vehicle (OSV) areas. They are prohibited elsewhere on Assateague Island."

Permits - Permits are issued for a 12-month period beginning with the month of purchase. Cost is $70 - $150, depending on type of access desired (as of 2012). All vehicles using the OSV zone must display a valid OSV Permit. Permits are issued for individual vehicles in the name of the registered owner. If the vehicle is sold or transferred to another owner the permit is voided. If the new owner can produce the original permit with the serial number and month sticker, a replacement permit may be issued. Permits destroyed in vehicle accidents may be replaced only if you bring an official accident report to the ranger’s station. They will not replace your destroyed permit if you can only produce the receipt of purchase. Permits must be permanently affixed to the driver's side front bumper. Expired permits must be removed or completely covered by the new permit. Permits are not refundable.

Maryland Permits - can be obtained at the Sinepuxent District Ranger Station or by mail. For more info, call 410-641-3030.

Virginia Permits - must be obtained at the Toms Cove Visitor Center (the OSV Closure Booth is open only in the summer) and at the Herbert H. Bateman Education Center.
