A “jackknife” accident occurs when the trailer of a tractor-trailer rig swings out from behind the cab at an angle like a folding pocket knife. The swinging trailer may collide with other vehicles or block multiple lanes, causing a serious wreck.
These accidents happen for many reasons, such as improper vehicle maintenance, icy or wet roads, driver error, or poorly loaded cargo. Understanding what causes a truck to jackknife can help you avoid being involved in a jackknife accident and keep you safe when driving near semi-trucks.
The truck accident attorneys at Fieger Law can help you file a compensation claim against the driver or trucking company if you’ve suffered injuries in a jackknife incident.
Causes of Jackknifing in Trucks
According to the Federal Motor Carrier Safety Administration, there were 169 fatal and 1,000 injury-causing jackknife crashes in the U.S. in 2020. These devastating collisions occur for many reasons, including the following:
- Driver Error
Sometimes, jackknifing can be caused by the driver’s actions, such as improper lane changes or sudden turns. A lack of experience or training can also contribute to jackknifing accidents, as can reckless driving, such as tailgating, improper passing, or drunk driving.
When a truck is traveling too fast for road conditions, it can lose control and jackknife. Speeding can cause a truck to jackknife due to the vehicle’s increased momentum, which makes braking or navigating curves in the road more challenging. If a truck driver suddenly brakes or swerves to avoid an obstacle, the momentum causes the trailer to swing out and jackknife.
- Sudden Braking
If a truck driver must make a sudden stop, the trailer’s weight can push the cab forward, causing the trailer to swing out and jackknife. This is especially likely to occur when the trailer is heavily loaded, and the driver uses improper braking procedures, such as inconsistent braking or slamming on the brakes.
- Overloaded or Unbalanced Cargo
Unbalanced or overloaded cargo on a trailer can affect its stability and increase the risk of jackknifing. These loading issues can throw off the truck’s weight distribution and balance, making it more difficult to maintain control of the truck and causing a jackknife.
- Mechanical Failure
Defective brakes or suspension systems can cause a truck to jackknife. If the brakes or suspension system are malfunctioning, the truck may not respond to the driver’s attempts to control it, leading to a jackknife accident. Bald tires can also cause the truck to lose traction and the trailer to swing out. Regular maintenance and inspections can help prevent these types of failures.
- Poor Road Conditions
Wet or icy roads can cause a truck to lose traction and jackknife. The tire tread on the trailer may be unable to grip the road. This increases the braking distance and may cause the trailer to slide out of control.
