But one of the more common types is the intersection crash, especially in urban areas. State Farm Insurance, the nation's largest auto insurer, says about one-third of all crashes happen at intersections. And a significant number of them are deadly. The rear-end collision seems to be the most common, probably because vehicles often are required to stop at intersections. Side-impact or angle collisions, potentially serious.
Frontal collisions are probably the least common.
Motorists are more likely to be hurt in crashes caused by red-light running than in any other type of urban crash. Failure to yield. It may take the form of a driver attempting a left turn in the face of oncoming traffic, or perhaps trying to make a right turn on a red light when the way isn't clear. Inattentiveness, such as talking on a cellular phone, tuning a radio or eating while driving, or simply being preoccupied and not paying enough attention to traffic. All of these are legitimate responses to the question of what caused the crash.
