About Commercial Auto Insurance
Commercial auto lines evolved alongside federal trucking reforms: GAO’s review of the Motor Carrier Act shows how loosening Interstate Commerce Commission controls still required fleets to prove financial responsibility so small-town shippers weren’t stranded, a balance we still strike for Hudson Valley contractors that run lean vehicle schedules.1
Deregulation then opened the market to thousands of new carriers, forcing underwriters to scrutinize driver quality, garaging, and route density before they priced a policy, which is why today’s coverage has to contemplate FMCSA filings, customer indemnity clauses, and even cross-border certificates before a unit leaves Nanuet.2
Modern filings build on that history: FMCSA refreshed the MCS-90 endorsement in August 2024 to keep Motor Carrier Act language current, and Clearinghouse II now forces any driver with a “prohibited” status to have their CDL downgraded within 60 days unless they complete the return-to-duty process, so underwriting decisions hinge on real-time compliance data.3,4
