Truck Accident Statistics

Data from the Insurance Institute for Highway Safety and the Highway Loss Data Institute show that most people killed in crashes involving large trucks are occupants of passenger vehicles. This reflects the greater vulnerability of people in smaller cars, especially because large trucks can weigh 20 to 30 times more and often sit high enough for smaller vehicles to slide underneath during a collision.

In 2023, crashes involving large trucks resulted in 4,354 deaths nationwide. Sixteen percent of those killed were truck occupants, while 65 percent were occupants of passenger vehicles. Another 17 percent included pedestrians, bicyclists, and motorcyclists. Compared with 2009, the year with the lowest number of large truck crash deaths since 1975, fatalities in 2023 were 38 percent higher. Deaths among truck occupants rose even more sharply, increasing by 58 percent.
