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.

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. These include car top weatherproof containers, some designed for specific cargo such as skis or luggage.
