Wanderlust World Wanderlust World Check the vehicle handbook to ensure that the items you want to load on the roof would not exceed the weight maximum permitted by the manufacturer. The weight consideration must include the roof rack. Weight restrictions generally are low, and a few large items can easily exceed the limitations.
Consider buying accessories that are recommended for your vehicle. These include roof racks, if the car did not come equipped with them; roof boxes that house items; bike racks and ski racks.
Secure all the items. Most local authorities say that loads must be secure and that items must not dangerously extend over the vehicle. Take time to secure the load, check that it is safe and then double check it.
Distribute the weight. Place bulky but light items on the roof and heavier items inside the vehicle. This will help maintain stability and reduce the chance of rollover in a high wind, on a sharp curve or if you shift lanes unexpectedly to avoid another car or object on the road.
Use strong rope to tie the front portion of any long load that overhangs the windshield to a part of the car under the front bumper. Otherwise airflow, caused by the vehicle's movement, can lift this kind of load.
Be prepared for load shifting. At faster speeds and quick or prolonged braking, the load could slide forward. All loads must be secured side-to-side and front-to-back. Bungee cords can be used to supplement strong rope.
Stop frequently to check for load shifts or loosened ties and knots. Readjust if needed.
Remember that the load makes your vehicle taller than normal. Determine the height to be sure you can safely clear objects such as garage openings, car parks, trees and bridges.
