Common Semitruck Accidents


Commercial truck crashes can happen in many ways.

And the circumstances of the collision can play an important role in determining who may be responsible:

Rollover Accidents: A semitruck can roll onto its side because of excessive speed, an unstable load, sharp turns, or other factors. Nearby motorists may have little time or room to react.

Jackknife Accidents: Jackknifing occurs when a truck’s trailer swings toward the cab at an angle. The trailer can sweep across multiple lanes and collide with surrounding vehicles.

Wide-Turn Accidents: Semitrucks need considerably more space to make certain turns. A driver who misjudges a turn may strike, squeeze, or trap a vehicle traveling alongside the truck.

Sideswipe Accidents: Large blind spots can make lane changes particularly dangerous. A semitruck may sideswipe another vehicle when merging, changing lanes, or drifting across lane markings.

Head-On and Rear-End Collisions: A semitruck that crosses into opposing traffic or cannot stop in time can cause a severe collision. The force involved may leave occupants of smaller vehicles with significant injuries.

Why Semitruck Accidents Happen

There are several causes of semitruck accidents, and determining why a crash occurred is essential to identifying the responsible parties and pursuing appropriate compensation:


  • Distracted Driving: Phones, navigation systems, in-cab devices, and other distractions can take a truck driver’s attention away from surrounding traffic.
  • Driver Fatigue: Long hours behind the wheel can affect alertness, reaction time, and decision-making, increasing the risk of a serious crash.
  • Mechanical Failure: Problems involving brakes, tires, steering, lights, or other equipment can contribute to a collision, particularly when maintenance has been neglected.
  • Oversized or Overweight Loads: Loads that exceed appropriate size or weight limits can affect a truck’s handling, braking distance, and stability.
  • Cargo Shifts: Improperly loaded or secured cargo can move during transit, upsetting the trailer’s balance and making the truck difficult to control.
