Coupling and uncoupling are high-risk manoeuvres if not performed correctly. This lesson provides a theoretical, sequential guide to the process, covering aligning the tractor unit, raising the trailer's landing gear, locking the fifth-wheel mechanism onto the kingpin, and performing a 'tug test' to confirm a secure connection. The uncoupling process is also detailed, emphasizing the importance of a firm, level surface.

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 The Coupling and Uncoupling Procedure (Theory) lesson explains one of the most important subjects in the Trailers, Semitrailers, Coupling, Articulation and Combination Behaviour 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 visualize the technical process of coupling and uncoupling, allowing you to answer complex exam questions regarding vehicle safety and standard operating procedures. You will understand the grave risks associated with improper coupling and be prepared to identify correct vs. incorrect procedures in test scenarios.
Beyond the theory exam, this knowledge ensures you can operate a vehicle combination with confidence, knowing the specific hazards like trailer roll-away or brake system malfunctions caused by poor connections. You will be able to apply these theoretical safety standards to your practical driving tasks, ensuring you maintain the highest level of responsibility as a professional goods vehicle driver in Switzerland.


This lesson is essential for candidates preparing for the Swiss Category C, C1, or CE theory exams who need to understand the practical mechanics of vehicle combinations. It is also highly recommended for professional drivers seeking to reinforce their knowledge of safety protocols in depot and loading environments.
