A jackknife accident occurs when a large truck, such as a semi-truck or tractor-trailer, loses control, causing the trailer to swing out to the side and form a 90-degree angle with the truck’s cab. This motion resembles the folding of a pocketknife, hence the term “jackknife.” These accidents are among the most dangerous incidents involving commercial trucks, often leading to severe injuries, multi-vehicle crashes, or even fatalities.

How does a jackknife accident happen?
Jackknife accidents typically result from losing traction between the truck’s tires and the road. When this happens, the trailer pushes forward uncontrollably, swinging to the side. Jackknifing can occur suddenly, leaving little time for the truck driver or surrounding vehicles to react.
There are two types of jackknife accidents:
- Trailer jackknife: The trailer’s tires lock up while the cab continues moving forward, causing the trailer to swing sideways.
- Cab jackknife: The cab’s drive axle tires lock up, while the trailer pushes forward, forcing the cab to swing out.
Both types of jackknife accidents can create immediate road hazards, block multiple lanes, and increase the risk of rollovers.
Causes of jackknife accidents in California
Jackknife accidents often result from driver error, mechanical issues, or hazardous conditions. Common causes include:
- Improper braking: Sudden or incorrect braking, especially on wet or icy roads, can cause wheels to lock and lead to skidding.
- Speeding: Excessive speed reduces control, particularly on curves or slopes.
- Hazardous road conditions: Rain, snow, debris, or poor road maintenance reduce traction and increase risks.
- Improperly loaded cargo: Unsecured or uneven cargo can destabilize the truck during stops or turns.
- Driver fatigue: Fatigue slows reaction times and increases mistakes, often linked to hours-of-service violations.
- Mechanical failure: Faulty brakes, worn tires, or malfunctioning ABS systems make it harder to stop safely.
Common injuries from jackknife accidents
The size and weight of commercial trucks make jackknife accidents particularly dangerous. Victims often suffer severe or life-threatening injuries, including:
- Traumatic brain injuries (TBI): Caused by head impacts or sudden jolts during collisions.
- Internal injuries: Caused by the force of the collision.
- Spinal cord injuries: Resulting in paralysis or reduced mobility.
- Broken bones: Common in high-impact crashes.
- Whiplash and soft tissue injuries: Due to sudden and forceful movements.
These injuries can lead to significant medical expenses, long-term rehabilitation, and emotional trauma.
Liability in California jackknife accidents
Liability in jackknife accidents often involves multiple parties:
- Truck driver: Liable for negligence such as speeding, fatigue, or improper braking, with compensation adjusted under California’s comparative negligence law.
- Trucking company: Responsible for vehicle maintenance, driver training, and enforcing safety regulations; failures in these areas can result in liability.
- Cargo loaders: Liable if improperly loaded or unsecured cargo contributed to the accident.
- Truck manufacturers: Defective parts, like faulty brakes, may make manufacturers accountable under product liability laws.
- Government entities: May share liability if poor road conditions or inadequate signage played a role.
Compensation for jackknife accident victims
Victims of jackknife accidents may be entitled to compensation for a range of damages, including:
- Medical expenses: Covers emergency care, surgeries, rehabilitation, and long-term treatment.
- Lost wages: Compensation for time missed at work due to injuries, as well as reduced earning capacity if the injuries result in long-term disability.
- Pain and suffering: Damages for physical pain, emotional distress, and reduced quality of life.
- Property damage: Reimbursement for damage to your vehicle or other personal property.
- Punitive damages: In cases of extreme negligence or reckless behavior, courts may award punitive damages to punish the at-fault party.
