What should you anticipate when you transport a load on the roof of your car?

When transporting a load on the roof of your car, it is crucial to understand how this affects vehicle dynamics. The vehicle will tilt more to the side when cornering because of the higher center of gravity. This can lead to decreased stability and an increased risk of tipping over, especially on sharp turns.

Additionally, a roof load makes the vehicle more susceptible to side winds, as the wind can catch the load and push the vehicle off its intended path, requiring a more cautious driving approach in windy conditions.

Lastly, an increase in fuel consumption occurs because the added weight and altered aerodynamics of the roof load require more power from the engine to maintain speed, resulting in higher fuel usage. This is essential to consider for both safety and efficiency.

The combination of these three factors is important for safe driving according to the rules outlined in the German Road Traffic Act (StVG) and related guidelines on vehicle operation. Understanding how a roof load influences handling and fuel efficiency helps ensure safer driving practices.
