Welcome to OS/OW Online Permitting!

NHDOT Permits will streamline your Oversize/Overweight permitting process. If you are moving a vehicle and/or a load that exceeds legal dimensions or weight, you can apply for your permits online 24 hours a day, 7 days a week, 365 days a year. Some permits will be automatically issued by the permitting system depending on dimensions, weight, routes, and current restrictions.

Permits that cannot be auto-issued will be processed in the order they are received by date and time requested during Monday - Friday between the hours of 8:00 AM - 4:00 PM EST, except holidays. Permit Office: (603) 271-2691 Fax: (603) 271-5990 or nhdotpermits@dot.nh.gov. See New System information in the Documents section.

Important News and Announcements

  • OVERLENGTH AND OVERHEIGHT LOADS
    • Loads greater than 110 feet in length and/or greater than 13 feet 6 inches in height require a Route Survey. The Route Survey form will be generated by NHDOT Permits based on the load information and route generated by the system. The applicant is required to download the system generated Route Survey form, complete the form by the applicant or a Route Survey company on behalf of the applicant, and upload the Route Survey form with the permit application. Route Surveys will be saved in the system and can be re-used by the same carrier for the same load criteria and route for up to 30 days after the Route Survey date.
  • CONSTRUCTION TRAVEL RESTRICTIONS AND ANNUAL ROAD POSTINGS:
    • All construction, maintenance, parade, and annual spring road postings on NHDOT maintained roads are managed within the restriction manager of the new permitting system. Details of restrictions can be obtained by clicking or hovering over the restriction(s) which are shown in red after the route is generated by the system on the routing page.
