180. Roof rack
A roof rack is a load-carrying system attached to the roof of a vehicle. It can be used to transport items such as luggage, bicycles, skis, surfboards or a roof box when they cannot conveniently be carried inside the vehicle.
A roof rack and its cargo must be securely attached and must remain within the vehicle manufacturer's permitted roof-load limit. Roof-mounted loads raise the vehicle's centre of gravity and can affect handling, stability, fuel consumption and overall vehicle height.

What can be carried on a roof rack?
A suitable roof rack can carry items such as luggage boxes, bicycles, skis and other equipment, provided the rack and attachments are designed for the load and the vehicle's permitted roof-load limit is respected.
Does a roof rack affect vehicle handling?
Yes. Weight carried high on the vehicle raises its centre of gravity and can affect stability, particularly during cornering or sudden manoeuvres. Drivers should secure the load carefully and adapt their driving accordingly.
How do you know the maximum roof load?
Check the vehicle manufacturer's specifications and the limits of the roof rack itself. The permitted load can vary significantly between vehicles, and the lowest applicable limit should not be exceeded.
