Truck accidents are often more severe than other types of accidents due to the size and weight difference between commercial trucks and passenger vehicles. Trucks can weigh up to 80,000 pounds, while the average passenger vehicle weighs around 4,000 pounds. The weight difference means that the force of impact in a truck accident is often much greater, leading to more serious injuries and fatalities. The height of the truck's center of gravity and the speed at which trucks are traveling can also increase the severity of truck accidents.
