This unit focuses on the unique characteristics and challenges of driving with trailers. It details the theoretical steps for safely coupling and uncoupling a semitrailer, including connecting air and electrical lines. Learners will explore the dynamics of articulated vehicles, such as off-tracking (cut-in) during turns, and learn to recognize the precursors to dangerous situations like trailer swing and jack-knifing.

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 Trailers, Semitrailers, Coupling, Articulation and Combination Behaviour unit is a key part of the Swiss Truck Driving Theory (C/C1) curriculum and helps learners in Switzerland understand essential theory topics in a clear and practical way. Each lesson breaks down a specific theme that often appears in the Swiss driving theory exam. With structured explanations and examples taken from real traffic situations, this unit helps learners study smarter, fix common misunderstandings, and build the knowledge required for confident exam performance.
Upon completing this unit, you will possess a thorough theoretical understanding of operating articulated vehicles within Switzerland. You'll be able to confidently explain the safe coupling and uncoupling processes for semitrailers, including connecting vital air and electrical lines. Critically, you will grasp the unique handling characteristics of combination vehicles, such as off-tracking during turns and the specific risks associated with rear swing and jack-knifing. This knowledge is crucial for passing the Swiss C/C1 theory examination and for ensuring safe, responsible driving practices on Swiss roads when operating heavy goods vehicles with trailers.


This unit is designed for individuals pursuing their Swiss Category C or C1 driving license, who will be operating heavy goods vehicles with trailers or semitrailers.
