18-Wheeler Accident Types
The way a truck crash happened tells you most of what the case will be about — what caused it, which companies may be responsible, and what evidence proves it. A jackknife points at braking, speed, and weather decisions; an underride points at guard equipment and conspicuity; a fatigue crash points at hours-of-service data and dispatch pressure. Find the crash type below to see how these cases are actually investigated.
Not sure which one fits? It doesn't matter for getting help — the free case review works the same either way, and the attorney will sort out the mechanics. These pages exist so you can understand what you're dealing with.
Jackknife Accidents
When a trailer swings past 45 degrees and sweeps across lanes, it can crush anything beside or behind the rig.
Causes, liability & evidenceUnderride Accidents
A passenger car slides beneath a trailer and the trailer bed shears into the passenger compartment — rear and side underride crashes are among the deadliest on American highways.
Causes, liability & evidenceTruck Rear-End Collisions
A loaded rig traveling 65 mph needs more than 500 feet to stop — when the driver doesn't leave that room, the vehicle ahead absorbs the impact.
Causes, liability & evidenceRollover Accidents
A high center of gravity, ramp speed, and shifting or liquid loads make tractor-trailers roll over where passenger cars would not.
Causes, liability & evidenceWide Right-Turn (Squeeze) Accidents
A trucker swings left to set up a right turn and traps the vehicle beside it in an unmarked blind spot — the classic "squeeze play."
Causes, liability & evidenceLost Load & Cargo Accidents
Unsecured freight that falls from a trailer strikes traffic directly or triggers chain-reaction crashes across multiple lanes.
Causes, liability & evidenceTire Blowout Accidents
Skipped inspections and worn retreads turn truck tires into highway debris and send 80,000-pound rigs out of control.
Causes, liability & evidenceHazmat & Tanker Accidents
Tanker and hazardous-materials crashes add fire, chemical spills, and toxic exposure to already severe truck-collision injuries.
Causes, liability & evidenceDriver Fatigue & HOS Violations
Federal law caps driving at 11 hours inside a 14-hour window — and the truck's own ELD data often proves the driver went past it.
Causes, liability & evidenceFatal Truck Accidents & Wrongful Death
When a crash takes a life, surviving family members may bring a wrongful-death claim — who may file, and by when, varies by state.
Causes, liability & evidenceWhatever the crash type, two things are true in every serious truck case: the carrier's team starts working within hours, and the truck's own electronic evidence — ECM data, driver logs — can be overwritten within days. The evidence guide explains what exists and how attorneys preserve it; the after-accident guide covers what to do right now.
