An extended permit shall be applied for electronically through MiTRIP. This application shall be accessed via MDOT Permit Gateway.
You may also obtain an extended permit through a permit service. However, you must register with MDOT MPG, add the task for oversize/overweight permits, click on the link once and select carrier from the dropdown prior to using a permit service. The permit services submit permits electronically as described above, and then forward them onto their customers.
If you still have questions regarding extended permits, contact the MDOT Transport Permits Unit at 517-241-8999.
