Speed bumps are designed to slow down vehicles as they travel over them. However, some drivers believe that speed bumps can damage low cars. There is no definitive answer as to whether or not speed bumps can damage low cars. It really depends on a number of factors, including the type of car, the height of the speed bump, and the speed at which the car is traveling when it hits the bump. In general, however, it is unlikely that a speed bump will cause significant damage to a low car if the car is driven over it at an appropriate speed.
