Most car accidents are the result of careless driving. It is usually the case that one or both drivers were not paying attention, speeding, or otherwise failing to drive cautiously. There are however times when accidents and injuries are not the result of a driver's error, but rather, are caused by a flaw in one of the vehicles involved in the accident. Sometimes the design of the car causes it to flip easily, or tires are flawed in such a way that they blow out easily. There are many different types of defects that a car might have, and some of them can lead to dangers for the individuals riding in the cars, and to other people on the road.
