What comes back
Two federal sources feed each result. FMCSA QCMobile returns the carrier's registered identity (legal name, DBA, physical address, USDOT and MC numbers), its operating authority and any out-of-service order, fleet size in power units and drivers, its crash counts for the trailing 24 months broken out by fatal, injury, and tow-away, and its vehicle, driver, and hazmat inspection out-of-service rates next to the national averages. FMCSA's insurance filings add the carrier's actual liability insurer, the policy number, the filed coverage limit, and the effective date.
Why this matters on day one
Most of what decides a truck case surfaces months later in discovery. This record is the part available before a case is even signed, and it answers the first questions in order. Who is the right defendant: the door of the truck and the registered legal name are often different companies, and the DBA field catches that. Is there money: the insurance filing names the insurer and the filed limit, which frames settlement value before the first phone call to an adjuster. Is there a story about the company: out-of-service rates well above the national average, a fleet of three trucks with a fatal crash on record, or lapsed operating authority each point toward carrier-level negligence rather than a one-driver mistake.
It also shapes the preservation letter. Knowing the carrier size and operation type tells you whether to expect ELD vendors, dashcams, and a telematics contract, and the registered address tells you where to send the letter so the clock on spoliation starts running.
What this does not tell you
The snapshot is the carrier's federal file, not the crash. It does not show fault, the driver's history, excess or umbrella policies above the filed minimum, or anything about a specific wreck. Crash counts are recorded regardless of who was at fault. Treat it as the starting frame: enough to name the defendant, size the coverage floor, and decide how hard to move in the first week.
