Primary Trucking Liability
The federally required commercial auto liability coverage for owner-operators running under their own FMCSA authority. It satisfies the MCS-90 endorsement filing requirement and covers bodily injury and property damage your truck causes to third parties while in commercial service. Minimum limits are set by federal regulation and vary by commodity type and vehicle weight. Brokers will not release loads without proof of primary trucking liability on file. For leased operators, the carrier's primary policy typically covers dispatched operations — but bobtail or non-trucking liability remains necessary for off-dispatch periods.
