Transport Permit Activities - 591-0171-18

Description of Agency

Michigan Department of Transportation’s (MDOT’s) Transport Permit Unit (TPU) issues permits associated with transporting oversized and/or overweight commercial vehicles and/or loads. For fiscal year 2017, TPU issued approximately 109,000 transport permits including 2,026 super load permits. The Michigan Transport Routing and Internet Permitting System (MiTRIP) is a Web-based system that enables applicants to submit permit applications and proposed routes online. TPU uses MiTRIP to review and approve the transport permit applications including route, vehicles, and load dimensions prior to approving and issuing the permits. For fiscal year 2017, transport permit revenue was $5.3 million.
