A roof rack is a set of bars secured to the roof of a motor car.
It is used to carry bulky items such as luggage, bicycles, canoes, kayaks, skis, or various carriers and containers.

There is a long history of the use of roof racks and their designs. They allow users of an automobile to transport objects on the roof of the vehicle without reducing interior space for occupants, or the cargo area volume limits such as in the typical car's trunk design.
