Transport permits are only issued for vehicles and loads which cannot reasonably be reduced in size or transported by other means.

Answer: Electronically submitted single trip permits are processed in the order in which they are received and are usually issued within twelve (12) business hours.

Answer: Extended permits are usually issued within 15 to 21 business days from the time it is received by the Michigan Department of Transportation (MDOT). Also, if the information submitted is inaccurate or incomplete, further information may be requested, which will delay issuance. Therefore, in order to ensure you receive your new permit prior to the expiration of your existing permit, MDOT recommends submitting the renewal application a minimum of 30 days prior to expiration of the existing permit. Permits can be applied for up to 60 days prior to expiration.

-top-

18. What if I am not receiving my permits in my email?

Answer: Ensure your email provider is not identifying the permit emails as spam and placing them in a separate folder.  If this is the case, many email providers allow you the opportunity to identify certain addresses that you would like to receive emails from.

28. Is transportation of oversize crated items legal in Michigan?

Answer: The Michigan Department of Transportation (MDOT) does not issue permits for crated items. However, exceptions can be given when the crate is necessary to maintain the integrity of the object. An example of this would be transport of precision electronic equipment that would be damaged by excess moisture from rain or snow. Prior MDOT management approval is required for such exceptions.

-top-

29. What are spring weight restrictions?

Answer: During the spring thaw, a soft layer below the pavement and above the frost line can create weakness in the pavement. This is most prominent on routes that are designated as seasonal and the shoulder portion of all routes.

For this reason, during the period of weight restriction a number of precautions are taken in order to protect the condition of the Michigan Department of Transportation (MDOT) jurisdiction infrastructure. First, reduced weight limits are in effect for seasonal routes. Seasonal routes are shown on the MDOT Truck Operators' Map. Signs are typically posted indicating seasonal limits on these routes. Secondly, overweight permits are not issued for any MDOT jurisdiction routes. Lastly, in order to protect shoulder conditions, permits for vehicles or loads exceeding 14 feet in width are not issued. Certain emergency situations may receive exceptions to these guidelines.
