Aside from the on-road collisions that happen every day, there are an astounding number of car-related injuries that occur when no one is behind the wheel, according to a report done by the National Highway Traffic Safety Administration (NHTSA). With almost 150,000 incidents a year, the most common injuries are those caused by closing a door, followed by 74,000 caused by a vehicle falling during maintenance and 10,000 as a result of using a jack or a lift. Other injuries include those caused by overexertion -- from pushing a car or loading and unloading cargo -- which totals to about 88,000 annually. The NHTSA gathered these results through police reports, death certificates and the number of fatalities recorded by the Not-in-Traffic Surveillance system. Many of these injuries and incidents can be prevented through using common sense and being cognizant when working on a car or going through your daily routine.
