The Insurance Institute for Highway Safety estimates that about 20 percent of vehicle accidents that cause damage take place in parking lots. One of the major sources of parking lot damage occurs when backing out of a parking spot, but this number is expected to drop following a recent Transport Canada regulation mandating that all new cars and small trucks must be equipped with rear-view cameras starting in May 2018, following a similar decision by the National Highway Traffic Safety Administration (NHTSA) in the U.S.
