High-sided lorries and trailers present a large surface area to the wind, making them susceptible to being pushed off course by strong crosswinds. This lesson highlights the danger, especially on exposed sections of road like bridges and viaducts, and when overtaking other large vehicles. It advises drivers to reduce speed and maintain a firm grip on the steering wheel when experiencing strong gusts.

This course provides the complete theoretical foundation for obtaining a Swiss Category C or C1 driving license. It details the specific regulations, vehicle dynamics, and safety protocols applicable to heavy goods vehicles. Learners will explore topics such as mass and dimension limits, advanced braking systems, professional responsibilities, and how to safely operate large vehicles on Swiss roads, including motorways and challenging mountain passes.
The Impact of Crosswinds and Adverse Weather on High-Sided Vehicles lesson explains one of the most important subjects in the Rural Roads, Mountain Roads, Motorways, Tunnels, Weather and Long-Distance Risks unit of the Swiss Truck Driving Theory (C/C1) curriculum. It focuses on essential exam content that every learner in Switzerland needs for the Swiss driving theory exam. Through clear explanations, practical examples, and real traffic situations, this lesson helps you understand how the rules work in practice and strengthens your overall exam preparation.
After completing this lesson, you will be able to anticipate potential loss-of-control scenarios caused by crosswinds, particularly when exiting tunnels or crossing high bridges. You will understand how to adjust your driving style, including reducing speed and increasing following distances, to compensate for the increased vulnerability of high-sided vehicles.
Furthermore, you will be prepared to answer complex theory exam questions regarding safe driving practices in adverse weather. By internalizing these techniques, you will transition from simple regulatory knowledge to applying advanced, safety-conscious defensive driving habits necessary for the professional operation of lorries and trailers on Swiss motorways and mountain passes.


This lesson is ideal for learners studying for their Swiss Category C or C1 heavy vehicle license who want to master advanced safety protocols.
