A type of parking maneuver

A trailer swinging out to form an acute angle with the towing vehicle

The term "jackknifing" specifically refers to a situation where a trailer swings out to form an acute angle with the towing vehicle, creating a V-shape. This typically occurs when a combination of factors such as speed, sudden braking, and slippery road conditions cause the trailer to lose alignment with the towing vehicle. Jackknifing is especially relevant for drivers of large vehicles like trucks or those towing trailers, as it can lead to loss of control, accidents, and significant safety hazards on the road.

Understanding this term is crucial for drivers of heavy vehicles because recognizing the potential for jackknifing can lead to safer driving practices. It underscores the importance of maintaining a steady speed, avoiding abrupt movements, and being aware of road conditions to prevent such dangerous situations.
