The National Highway Transportation Safety Administration reports the most common type of car accident is the rear end collision. The agency states this type of crash accounts for 30% of all car accidents. The NHTSA found in a 2007 study that drivers in rear end accidents are often engaged in activities that take their attention from their driving. Also, 64% of people in rear end crashes were not looking at the roadway when the crash happened.

Another common type of car crash is the side impact crash. The NHTSA stated in 2009 that these accidents were 27% of all accident deaths in America. These accidents include the classic T bone collision that happens when one driver does not stop at an intersection where the other has the right of way. These accidents are more likely to be fatal because the sides of cars and trucks do not have the same amount of energy absorption potential as the front and rear of vehicles.

The third most common type of car accident is the single vehicle crash that can happen for a variety of reasons. This accident is especially common for teen drivers. Common reasons include running off the road due to fatigue or distraction, slipping on ice and hitting stationary objects.
