Heavy Truck Accident Causation: Analysis of the CPIR-B File

摘要

Analyses compared accident characteristics and causal factors of accident-involved articulated and heavy straight trucks. Relative to straight trucks, articulated vehicles were more likely to be involved in single vehicle accidents, on curves, on higher speed, limited access roads, and in rural areas. Multiple vehicle accidents of articulated vehicles were most likely to involve vehicles traveling in opposite directions, or in the same direction, rather than from the sides. By comparison, straight truck multivehicle accidents were most likely to involve intersecting paths or turning movements.
