Permits
ODV permits are issued only by NDOT's Carson City office or online. Ports of entry do not issue them. The original signed permit must be carried; copies are not allowed. Permits may carry restricted-route, spring thaw and weight-restricted bridge attachments.
Superloads must be submitted online at least 10 business days before the move: over 17 ft wide on 2-3 lane highways, over 19 ft wide on 4+ lanes, over 18 ft tall (route survey required), over 200 ft long, or over 500,000 lb.
Permit fees: verify with the state.

When you can roll
NDOT restricts ODV travel around New Year's, Memorial Day, July 4, Labor Day, Thanksgiving and Christmas, during the high-traffic hours shown in its charts (these may not fall on the holiday itself). Weekend hours run from ½ hour after sunset Friday to ½ hour before sunrise Monday; hours of darkness are ½ hour after sunset to ½ hour before sunrise. The exact restriction for each width class: verify with the state (see NDOT's holiday charts and your permit).
