General Permit Requirements

  • All loads traveling on State or Federal routes do not need to obtain a permit from Scottsdale - so long as they do not leave those routes. If they do, they must apply for the appropriate permit from Scottsdale and submit all required documentation to Traffic Engineering.
  • All loads traveling on Scottsdale roads (other than State or Federal roads) must stay on the approved routes depicted on the current map of approved truck routes. Loads leaving these routes must provide a copy of the proposed route plan, along with weights, dimensions, axles, etc. and obtain a pre-approval from Traffic Engineering.
  • Where an envelope permit's load destination is Scottsdale, the return trip requires a paid Scottsdale permit.
  • When applying for a Letter of Authorization (a companion to an envelope permit) due to the load leaving State or Federal roads, a copy of the envelope permit must be submitted along with all required documents, and pre-approval must be obtained.
  • Loads being transported using an annual permit must remain on the currently approved truck routes, and may not exceed the dimension and load limitations for which the permit is issued. If they do, they must obtain pre-approval from Traffic Engineering.
  • It is the customer's responsibility to confirm loads and validate routes. It may be necessary to hire a professional surveyor to provide Traffic Engineering a certified letter that validates the loads and routes.
  • Permits are issued for a specific vehicle, identified by the vehicle identification and license plate numbers. Permits are not transferable to other vehicles.


Customers should allow 5-10 business days for processing of applications.
