Whiplash is a very common injury, as are many other neck injuries. This is largely because when the force of one car hitting another rattles the car, and passengers in it, the head can tend to snap back & forth or side to side very violently.
Other common car accident injuries include soft tissue injuries – basically cuts, scrapes, bruises & sprains. With more severe crashes, more catastrophic injuries such as broken bones, head injuries, and sometimes fatalities can occur. Wearing a seatbelt is always a good idea and helps make sure the injuries sustained in an auto accident are on the less severe end of the spectrum.
