By FMCSA's public insurance file (November 14, 2026): Progressive Michigan Insurance Company (781 Michigan companies), Great West Casualty Co (429 Michigan companies), Amerisure Mutual Insurance Company (149 Michigan companies). That counts filings on record, not price or service.
For-hire carriers hauling general freight across state lines need at least $750,000 in primary liability on file with FMCSA (form BMC-91 or BMC-91X), with higher minimums for some hazardous materials. Brokers need a $75,000 bond or trust (BMC-84 or BMC-85). Trucks that run only inside one state can fall under that state's rules instead.
Trucking policies are usually sold through licensed agents who work with several insurers. Get quotes from more than one. The insurers above already write trucking policies for companies in this state, so ask an agent about them, or ask us to point you to one.
Search the company in Carrier Lookup or open its carrier page. The Licensing and Insurance section lists each FMCSA filing with the insurer and the date the policy took effect.
