You can avoid permit delays caused by route entry errors. When beginning or ending your route on an interstate and state highway junction, you are required to identify the starting location and enter the correct proximity offset.
Self-routing of trips under annual permit is no longer allowed. All routing must be done through our online permitting system.
You can apply for permits online, by mail or through an independent permit service - not by fax or phone.
If MnDOT approves your application and issues a permit, we will charge the appropriate permit fee to the credit card you have listed with us. Please indicate on your application form which credit card to use.
