The combination of a trailer and load presents significant hazards on motorways, particularly due to high speeds and sharp curves. Proper loading is crucial to prevent load displacement during heavy braking or sudden directional changes. A load shift, especially when the centre of gravity is high, can initiate critical situations, increasing the risk of tipping and rolling. This paper analysis the critical situations, emphasizing drivers responsibility in ensuring safe loading practices to avoid causing dangerous road conditions, such as vehicle overturning. Such incidents are unfortunately common. The paper will explore characteristic vehicles, safety systems, cornering dynamics, and both theoretical and practical demonstrations of load behaviour under various forces. Side-slip and rollover phenomena will also be examined.
