Jackknife crashes remain one of the most serious hazards involving large commercial vehicles because they involve a complete loss of control.
A jackknife occurs when the tractor and trailer fold toward each other, creating a sharp angle that can sweep across lanes and strike multiple vehicles. These events often unfold within seconds and leave little room for surrounding drivers to react.
Factors that cause semis to jackknife
Sudden braking is one of the most common triggers in jackknife wrecks because the trailer continues moving forward while the cab slows down. Poor weather conditions can also reduce traction and increase the likelihood of skidding.
Rain, snow, ice and high winds all make it more difficult for a driver to maintain control. Mechanical failures, such as worn brakes or tire blowouts, can also contribute. Improperly loaded or imbalanced cargo may shift during travel and cause the trailer to swing outward during turns or evasive maneuvers.
Driver error can cause crashes
Driver behavior plays a significant role as well. Speeding, drowsy driving and impaired driving all increase the risk of a jackknife. Overcorrecting during a sudden maneuver can also cause the trailer to swing out of alignment. Once the trailer begins to slide, the driver may have limited ability to regain control, especially if the roadway is slick or visibility is reduced.
Preventing jackknife crashes requires consistent attention to vehicle condition and driving practices. Regular inspections help ensure that brakes, tires and suspension systems are functioning properly.
How drivers can be safer
Safe driving techniques such as maintaining a long following distance, avoiding sudden stops and adjusting speed for weather conditions are essential. Drivers must also remain alert to shifting road conditions and avoid relying on cruise control during rain or snow.
When a jackknife begins, corrective action must be immediate. Releasing the brake pedal can help the trailer realign with the cab. Steering into the skid rather than away from it can also help bring the vehicle back under control. These maneuvers require training and experience, and even skilled drivers may be unable to recover if conditions are severe.
