This lesson addresses the causes and prevention of trailer sway and jack-knifing, two critical loss-of-control events. It explains how factors like improper braking, high speeds, crosswinds, and poor load distribution can trigger these dangerous situations. Learners will study avoidance strategies, including proper speed management and smooth steering inputs, as well as corrective actions to regain control if sway begins.
This comprehensive course provides essential knowledge for aspiring professional drivers of heavy goods vehicles in Denmark. It details the legal and practical aspects of operating lorries and combinations, focusing on vehicle mass, load management, and advanced braking systems. Learners will understand the specific rules and road situations relevant to heavy transport, preparing them for the official theoretical examination for a C-category licence.
