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 or less based on changes to transportation infrastructure of restriction conditions.

      Submittal of a completed and signed route survey is an attestation that the route has been surveyed by driving the route provided on the route survey form and the vehicle and load can safely complete the trip including all dimensions provided on the route survey form. Submitted route surveys must include any obstructions, dimensional conflicts, special driving directions including lanes of travel, speeds, and traffic control requirements. Route surveys are part of the information the applicant provides to obtain a permit and are a condition of the permit. The Driver's signature on the permit certifies that all information is accurate and complete. Permits are signed under penalty of unsworn falsification pursuant to New Hampshire RSA 641.3.
