Large trucks — semi-trucks in particular — are more likely to catch fire in higher speed vehicle crashes compared to light trucks and passenger vehicles, according to a recent study by the Kentucky Injury Prevention and Research Center (KIPRC).

In the study of Kentucky motor vehicle collisions between the 2000 and 2009, the large truck fire rate was 113% higher than the light truck/passenger car fire rate — 14% of vehicles that caught fire after a motor vehicle collision were large trucks. 
 

Although many of Kentucky’s 762 mi. of Interstate highway includes twists and curves, the study showed most large truck fires occurred on long stretches of straight highway, with a steady speed of at least 55 mph, and the majority of these large truck fires occurred in single-vehicle accidents involving only the truck and its driver.
