When the demand for spaces outstrips supply vehicles may overspill park onto the sidewalk, grass verges and other places which were not designed for the purpose . </P> <P> For most motorised vehicles, there are three commonly used arrangements of parking spaces--parallel parking, perpendicular parking, and angle parking . These are self - park configurations where the vehicle driver is able to access the parking independently . </P> <P> With parallel parking of cars, these are arranged in a line, with the front bumper of one car facing the back bumper of an adjacent one . This is done parallel to a curb, when one is provided . Parallel parking is the most common mode of streetside parking for cars . It may also be used in parking lots and parking structures, but usually only to supplement parking spaces that use the other modes . </P> <P> With perpendicular parking, also known as bay parking, cars are parked side to side, perpendicular to an aisle, curb, or wall . This type of car parking fits more cars per length of road (or curb) than parallel parking, and is therefore commonly used in car parking lots and car parking structures . </P>
