What are the Most Common Causes of Large Truck Accidents?

Causes of Large Truck Accidents

The National Highway Traffic Safety Administration (NHTSA) reported that in 2019 more than 5,000 people were killed and an estimated 159,000 people were injured in crashes involving large trucks. Across the United States, an estimated 538,000 large trucks were part of crashes on a public road or highway, with 75 percent of fatalities involving a truck with a gross vehicle weight rating of 26,000 pounds.

Of those killed in 2019:

  • 71 percent were occupants of other vehicles
  • 18 percent were occupants of large trucks
  • 11 percent were pedestrians, cyclists, and other nonoccupants

Of those injured in 2019:

  • 69 percent were occupants of other vehicles
  • 29 percent were occupants of large trucks
  • 2 percent were pedestrians, cyclists, and other nonoccupants

What Is a Large Truck?

A “large truck” is defined as a commercial or noncommercial truck with a gross vehicle weight rating of more than 10,000 pounds, excluding buses and motor homes. For comparison, the average passenger vehicle made in 2020 weighs just over 4,000 pounds.

What Are the Top Causes of Large Truck Accidents?

The NHTSA and the Federal Motor Carrier Safety Administration carried out a Large Truck Crash Causation Study for the period of April 2001 through December 2003. The study examined a sampling of the 120,000 large truck crashes that occurred during this period and resulted in a fatality or an injury.

The study concluded that there were many factors contributing to any vehicle accident, but it noted several key factors that led to a large truck accident that resulted in a fatality or injury. Driver error and vehicle malfunction were considered significant contributors to both fatal and injury crashes.

The study pointed out that “motor vehicle crashes are complex events. Usually they involve two or more vehicles. Elements that influence the occurrence of a crash may take place hours, days, or months before the crash.” Driver experience, road conditions, and changes in weather are things that can influence whether an accident takes place and how serious the outcome is when one does happen.

The study added, “Fatigue, drinking alcohol, and speeding are major factors in motor vehicle crashes overall. Although their presence does not always result in a crash, these three factors, as well as other driver, vehicle, and environmental factors, can increase the risk that a crash will occur.”

Three Categories of Truck Accident Causes 

The causes for large truck crashes that resulted in fatalities or injuries were divided into three categories for the study. The main specific reasons for large truck fatal and injury crashes are included here with each category.

  1. Critical events (making the crash unavoidable):
  • running out of the travel lane
  • losing control of the truck (for example, speeding or a shifting cargo)
  • rear-ending another vehicle in the truck’s travel lane
  1. Critical reasons (actually causing the crash):
  • truck driver error
  • truck malfunction
  • environmental conditions
  1. Associated factors (conditions present at the time of the crash) (top 10):
  • brake malfunction
  • traffic flow interruption
  • truck driver using prescription drugs
  • truck driver traveling too fast for conditions
  • truck driver unfamiliar with road
  • road problems
  • stop required before crash (for example, at a crosswalk)
  • truck driver using over-the-counter drugs
  • inadequate awareness of surroundings and conditions
  • truck driver fatigue

Under critical reasons, truck driver error included four categories:

  • nonperformance (for example, fell asleep, disabled by heart attack, physically impaired)
  • recognition (for example, inattentive, distracted)
  • decision (for example, driving too fast for conditions, misjudged speed of other vehicles, followed other vehicles too closely)
  • performance (for example, panicked, overcompensated, poor directional control)
