Why a truck claim is built differently from a car claim
The difference starts with a definition. Federal law treats a vehicle as a commercial motor vehicle when its weight rating is 10,001 pounds or more, when it carries more than 8 passengers including the driver for compensation or more than 15 without, or when it carries hazardous materials in a quantity requiring placards (49 CFR 390.5). Once a vehicle sits on that side of the line and runs in interstate commerce, the driver, the company and the equipment fall under the Federal Motor Carrier Safety Regulations. In an ordinary collision the duty is the general one every driver owes; here much of the conduct was already spelled out in a rule, and a rule that was broken is easier to prove than carelessness that was not.
The money looks different too. A for-hire carrier moving general freight in interstate commerce at 10,001 pounds or more must keep at least $750,000 of public liability coverage, rising to $1,000,000 for oil and for hazardous waste, materials and substances not otherwise listed, and to $5,000,000 for the bulk hazardous cargoes the schedule sets out by division and hazard zone (49 CFR 387.9). Carriers of passengers run on a separate schedule: $5,000,000 for a vehicle seating 16 or more including the driver, and $1,500,000 for 15 or fewer (49 CFR 387.33). The ordinary auto floor in our state legal database is $25,000 of bodily-injury coverage for one injured person in 36 of the 51 jurisdictions, so in most serious truck cases the ceiling on recovery is the evidence and the state rules rather than the size of the policy.
Finally, the defendants multiply. The motor carrier is normally answerable for the driver’s on-the-job conduct under respondeat superior, and answerable separately for its own choices about whom it hired, how it trained and dispatched, and how it maintained the equipment. Where the tractor belongs to an owner-operator, the federal leasing rule closes the obvious gap: the lease must provide that the authorized carrier has exclusive possession, control and use of the equipment for the term of the lease and assumes complete responsibility for its operation (49 CFR 376.12(c)(1)). That sentence is why a carrier rarely walks away by calling the driver an independent contractor. Add whoever loaded the trailer, serviced the brakes or arranged the freight and one collision can produce four or five insured defendants with separate counsel and separate coverage.
