A commercial truck accident can be much more catastrophic than an accident between two personal-use vehicles. A typical, fully loaded commercial truck (such as a big rig or dump truck) can weigh at least 25 times as much as a typical car. Due to this stark weight disparity and the basic laws of physics, most big rig truck accidents with other vehicles result in serious, even fatal, injuries.

If you or a loved one is involved in an accident with a commercial truck, you may be entitled to recover compensation for your injuries by bringing a legal claim against the responsible parties.

Proving Your Case

As is true in most personal injury cases involving vehicle accidents, the main legal theory of liability in commercial truck accident cases is “negligence.” Therefore, a person injured in a commercial truck accident must show that:

  1. Defendant (driver, trucking company, etc.) owed the plaintiff the duty to exercise a reasonable degree of care to avoid injury, under the circumstances (all drivers on the road owe a legal duty of reasonable care to fellow drivers, passengers, and pedestrians);
  2. Defendant failed to exercise such reasonable care, or in legal terms “breached” the duty of reasonable care; and
  3. Defendant’s failure to exercise reasonable care was the cause of injury suffered by the plaintiff.

Potential Defendants

In order to collect for injuries suffered in a truck accident, it is important to identify as many potential defendants as possible, which may not be limited to the driver. In many cases, trucking companies, contractors, employers, and insurance companies may be obligated to compensate you for your injuries.

If an employment relationship is established between the truck driver and a trucking or shipping company, then that company may be held legally liable for the driver’s negligence. Proving your case can be difficult, as you would need to show that the company exercised some degree of control over the driver, and that the accident occurred while the driver was acting in the course of the employment relationship.


If you are involved in a truck accident where the truck driver was at fault, you may be entitled to damages — financial compensation for physical, emotional, and/or financial losses resulting from the accident.

Special Considerations in Truck Accident Cases

The operation of large commercial trucks (especially big rigs) on highways and roads presents certain unique dangers that are not a consideration where ordinary passenger vehicles are concerned:

  • Jackknifing — Large vehicles such as eighteen-wheelers are prone to jackknifing under certain conditions, especially during sudden braking and turning. The driver of a truck that has jackknifed (or other would-be defendants) may be not be held negligent where the jackknifing was due to unforeseeable slipperiness of the road, or an abrupt turn to avoid a motorist or stalled truck.
  • Turning Accidents — Commercial trucks can be difficult to turn, often requiring the use of two lanes to make a right turn. It is not always a clear case of negligence, but some courts have held that driving a big rig in this manner (turning from an inside lane or occupying two lanes) is sufficient to establish the truck driver’s fault.
