Auto transport insurance requirements: what the law actually says
Most carriers and brokers describe cargo insurance as federally mandated. That is not accurate, and knowing the difference tells you which questions are worth asking.
What the FMCSA does require. Every for-hire interstate motor carrier running vehicles over 10,001 pounds must carry a minimum of $750,000 in public liability coverage (bodily injury and property damage) under 49 CFR 387.9, and must keep proof of it on file with the FMCSA. In practice, almost every reputable car hauler carries $1,000,000, because brokers and shippers insist on it. That coverage protects other people and property in an accident, not the car on the trailer.
What the FMCSA does not require. Cargo insurance is not federally mandated for auto transport. The federal cargo minimums ($5,000 per vehicle, $10,000 per occurrence) apply only to household-goods movers, and auto transport is classified as general freight. So the coverage that actually pays if your car is damaged is contractual, not statutory. It exists because brokers refuse to book carriers without it, not because a regulation forces it.
What that means for you. A carrier can be fully legal, fully authorized, and still carry little or no cargo coverage. This is exactly why the verification step below matters, and why we confirm active cargo coverage on every carrier before your vehicle is loaded rather than taking the authority number as proof.
Brokers have their own requirement. Licensed property brokers must hold a $75,000 surety bond or trust fund (FMCSA form BMC-84 or BMC-85). That bond is financial protection on the brokering side of the transaction; it is not vehicle damage coverage. Any company that presents its broker bond as though it insures your car is blurring two very different things.
