The fifth wheel is the critical link between the tractor and semitrailer. This lesson details a visual inspection of the coupling, focusing on ensuring the locking jaws are secure, the safety latch is in place, and there is adequate lubrication on the skid plate. A thorough check of the fifth wheel mechanism is a non-negotiable part of the pre-drive inspection and after every coupling procedure.
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 Inspecting the Fifth Wheel and Coupling Devices 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.
After finishing this lesson, you will be able to confidently describe the technical inspection process for heavy vehicle coupling systems.
