In a car crash you sue a driver. In a truck crash you may have claims against six different parties — driver, carrier, broker, maintenance shop, cargo loader and manufacturer — each with its own policy. Finding every liable party is the single biggest value lever in truck settlements.
The six potential defendants
| Party | Liable when | Why it matters |
|---|---|---|
| Driver | Fatigue, speeding, impairment, HOS violations | Baseline claim; logs prove it |
| Motor carrier | Negligent hiring/training, pushing schedules, vehicle condition | Vicarious liability + the big policy |
| Broker / shipper | Hired a carrier with a bad safety record | A growing theory with real verdicts |
| Maintenance contractor | Brake, tire, light failures | Third-party policy stacks on top |
| Cargo loader | Shifted or overweight loads | Load-securement rules are strict |
| Manufacturer | Defective brakes, tires, underride guards | Product liability — different clock |
The evidence that decides it — and its expiration dates
Modern trucks are rolling data centers: engine control modules, ELDs, dashcams, GPS pings, dispatch messages. But some of that data can be overwritten within days and trucks get repaired or salvaged fast. The single most important early move is a spoliation (preservation) letter to the carrier and its insurer — it legally freezes the black box, camera footage, logs, inspection records and the truck itself. Sent in week one, it preserves the case; skipped, the best evidence often “no longer exists.”
HOS: the violation hiding in plain sight
Federal hours-of-service rules cap driving at 11 hours within a 14-hour window with mandated breaks. ELD data comparing driving time against pickup/delivery stamps regularly exposes violations — and a carrier whose dispatch schedule REQUIRED breaking HOS turns an accident case into a negligence-per-se case with punitive exposure. This is why carriers settle documented-fatigue cases before trial.
One crash, many policies — how they stack
The carrier’s $1M policy pays first; maintenance contractors, brokers and manufacturers add theirs above it. In catastrophic cases, layered “excess” policies (carriers often hold $5M+ in umbrella coverage) come into play. Your own underinsured-motorist coverage can top up the stack too. The practical takeaway: never assume the first disclosed policy is the whole pie — demand disclosure of ALL coverage in discovery.

FAQ
The police report only names the driver. Is that final?
No — police assign traffic fault, not civil liability. Carrier, broker and maintenance liability emerge from records, not the roadside.
What does a preservation letter cost?
An attorney sends it as routine intake — effectively free with representation. Template letters exist for the determined self-represented, but serious truck cases justify counsel: when self-representation works (and when it does not).
The trucking company already called me offering help. Normal?
