Commercial Motor Vehicle crashes may be caused by one or more sets of factors. Oftentimes it is difficult to isolate a single cause, and potentially even more difficult to demonstrate responsibility or fault. Common crash factors include:
Driver factors such as fatigue are especially precarious because, unlike mechanical problems such as deficient tires, they cannot be identified or remedies in advance of a long drive. A worn-out tire or a malfunctioning steering system can be spotted during a maintenance survey, and repaired before the drive begins. Fatigue, by contrast, emerges as an extremely high risk slowly, imperceptibly, and while the drive is still underway.
