Statewide Heavy Truck Crash Assessment

In 2009, heavy trucks represented approximately 15% of the vehicle miles traveled (VMT) in Iowa, compared to 10% at the national level . Between 2006 and 2010 in Iowa, heavy trucks were involved in crashes resulting in, on average, 74 fatalities annually. Fifteen percent of these fatalities were large truck occupants. In other words, the vast majority of the resulting fatalities were non-large truck occupants, demonstrating the serious nature of these crashes when involving the general traveling public. While several national studies have investigated heavy truck crashes, e.g. "Large Truck Crash Causation Study", no rigorous analyses have been conducted in Iowa. The objective of this project is to investigate the causes, locations, and other factors related to heavy truck crashes in Iowa. Through efforts related to this study, the research team will provide results that may be used by decision makers and law enforcement, particularly Iowa Department of Transportation Motor Vehicle Enforcement (MVE), in establishing priorities and allocating limited resources to promote safety and reduce crashes.
