What is "jackknifing" in trucking?

Jackknifing refers to a dangerous situation that occurs when the trailer of a truck swings out to the side of the towing vehicle, much like the hinge of a folding knife. This typically happens during sudden braking or loss of traction, causing the trailer to pivot around the hitch point. As a result, the truck and trailer form an angle that can lead to a complete loss of control, putting the vehicle and others on the road at significant risk. Understanding this concept is crucial for truck drivers and those preparing for the CDL exam because recognizing the signs of potential jackknifing can help in preventing accidents. The other options do not accurately describe jackknifing; while they may relate to truck operation or safety, they do not capture the specific mechanics of how jackknifing occurs and the dangers it poses on the road.
