Wet or icy roads drastically reduce tyre grip and can double or triple braking distances. This lesson stresses the importance of significantly reducing overall speed and increasing following distances in such conditions. It advises on using brakes with extreme care to avoid skidding and explains how the vehicle's retarder should be used with caution as it can cause the drive wheels to lock up on slippery surfaces.

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 Braking in Adverse Weather Conditions lesson explains one of the most important subjects in the Heavy-Vehicle Braking Systems, Speed, Distance and Downhill Control 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.
By the end of this lesson, you will be able to confidently handle complex braking scenarios that frequently appear on the official Swiss theory test. You will know exactly when to rely on endurance braking and when to prioritize service brakes to avoid locking wheels or losing traction on icy inclines.
Beyond exam preparation, these skills are vital for your real-world professional career. You will develop the professional judgment necessary to assess road conditions dynamically, ensuring the safety of your cargo and other road users in unpredictable Swiss climate conditions.


This lesson is essential for all Category C and C1 license candidates preparing for the Swiss theory exam. It is especially useful for those who want to understand the physics of driving heavy vehicles on challenging mountain passes or during winter months.
