What is a potential hazard when operating combination vehicles?

When operating combination vehicles, one of the primary hazards is the difficulty in navigating tight turns and narrow roads. Combination vehicles, which consist of a tractor unit and one or more trailers, typically have a longer wheelbase and larger overall dimensions than standard vehicles. This makes sharp turns challenging, as the rear trailer may swing out or off-track, leading to potential collisions with obstacles, other vehicles, or even pedestrians.

Additionally, when maneuvering in confined spaces or urban settings, the driver must take into account the vehicle's larger turning radius, which can lead to issues when trying to fit through narrow passages or around sharp corners. This can require more careful planning and awareness of surroundings compared to operating a standard vehicle and presents a significant risk if not managed properly.
