What are the most common factors in collisions between commercial trucks and automobiles?

Legal professional: I may be a little biased in answering this question, because I frequently represent the victims of accidents, and they’re usually in the automobile. The most common factor is the truck driver simply not paying attention. Other factors can be violation of applicable safety regulations, the truck driver’s being on the road for an extended period. They’re fatigued and as a result, they’re half falling asleep, thereby causing an accident.
