Step-by-step explanation:
The most common type of turning accident in a CMV (Commercial Motor Vehicle) is Jackknife accidents. Jackknifing occurs when the trailer of a CMV swings out at a sharp angle towards the cab, resembling the shape of a folding pocket knife.
This type of accident typically happens when the wheels of the trailer lose traction with the road surface, causing it to skid and swing out of control. Factors such as excessive speed, sharp turns, and adverse road conditions can contribute to jackknife accidents.
Drivers can help prevent jackknifing by practicing defensive driving techniques, maintaining safe speeds, and being aware of potential hazards on the road.
