A draft study by the American Automobile Assn. Foundation for Traffic Safety shows that unsafe driver actions are much more likely to be recorded for car drivers than for truck drivers.

Oliver Patton reports in the April issue of Heavy Duty Trucking that the study found four particular risk factors among car drivers: fatigue, following improperly, vision obscured by outside conditions, and improper lane changes.
The study confirms what truck drivers often say, that one of the biggest dangers on the highway is unsafe driving by "four-wheelers."
Patton notes that the foundation is an unexpected source for this information. As the research arm of the AA, the foundation typically takes the perspective that cars are victimized by trucks.
