What Causes Jackknife Truck Accidents in California?

A jackknife truck accident can happen in seconds. When a tractor-trailer suddenly loses control and its trailer swings outward, it can sweep across multiple lanes, strike nearby vehicles, and cause devastating injuries.

These crashes can happen because of excessive speed, sudden braking, slippery roads, driver fatigue, improper cargo loading, mechanical problems, or other factors. But after a serious crash, the bigger questions are often

why the truck jackknifed, who may be responsible, and what can be done about the injuries and losses that follow.

If you were injured in a jackknife truck accident, you may be facing medical treatment, lost income, property damage, and an insurance company that wants to resolve the claim quickly. A Los Angeles trucking accident lawyer can investigate what happened and help you understand your legal options.

What Exactly Happens in a Jackknife Truck Accident?

A jackknife accident occurs when a truck’s trailer swings sideways while the tractor continues moving forward. The two sections can form an angle resembling the blade of a folding knife.

Once a large truck begins to jackknife, nearby drivers may have very little time to react. The trailer can cross several lanes, hit multiple vehicles, or trigger additional collisions.

Jackknife crashes are one type of truck-involved accident that can result in significant property damage and serious injuries.

Why Do Large Trucks Jackknife in California?

There is not always one obvious reason a truck jackknifes. The circumstances leading up to the collision can involve the driver’s actions, road conditions, the truck itself, or the way its cargo was handled.

Potential contributing factors include:

• Excessive speed
• Sudden or improper braking
• Wet or slippery roads
• Loss of traction
• Sudden steering movements
• Driver fatigue
• Distracted driving
• Improperly loaded cargo
• Mechanical or maintenance problems
• Sudden changes in traffic

For example, a truck traveling too fast for the road conditions may have difficulty maintaining control when the driver needs to brake suddenly. A problem with the truck or its cargo may also affect how it responds.

Understanding what caused the loss of control can be critical when determining whether negligence contributed to the crash. Read more about the common causes of truck accidents.

Why Can a Jackknife Truck Crash Cause Serious Injuries?

The size and weight of commercial trucks can make jackknife collisions particularly dangerous for people in passenger vehicles.

Depending on where and how the truck strikes another vehicle, victims may suffer:

• Broken bones
• Traumatic brain injuries
• Spinal cord injuries
• Neck and back injuries
• Internal injuries
• Severe cuts and lacerations
• Permanent disabilities
• Emotional trauma

Some victims require extensive treatment and rehabilitation. Others may face injuries that permanently affect their ability to work or enjoy everyday life.

When a truck crash results in permanent or life-altering harm, the consequences can extend far beyond the initial medical bills. Hakim Injury Law also handles catastrophic injury cases involving serious, long-term injuries.

Who Could Be Responsible for a Jackknife Truck Accident?

The fact that a truck jackknifed does not automatically establish who is legally responsible.

Depending on the circumstances, potentially responsible parties could include:

• The truck driver
• The trucking company
• The truck or trailer owner
• A maintenance provider
• A cargo-loading company
• Another party whose conduct contributed to the collision

The investigation should look beyond the final moment of the crash. It may need to determine what happened before the truck lost control and whether another party’s actions or omissions contributed to the accident.

How Can You Prove the Truck Driver or Company Was Negligent?

A jackknife accident by itself does not necessarily establish negligence. The evidence needs to connect the conduct of a driver, trucking company, or another party to the collision and resulting injuries.

That may involve determining:

• What happened immediately before the crash
• Whether the truck was being operated safely
• Whether road conditions played a role
• Whether the truck or trailer had maintenance problems
• Whether cargo was properly loaded
• Whether the driver was fatigued or distracted
• Whether another party contributed to the loss of control

A police report can provide important information, but it may not tell the complete story.

In a complicated truck accident claim, additional records and evidence may be needed to establish what actually happened.

What Evidence Can Help Prove Your Jackknife Accident Claim?

Evidence can become particularly important when the cause of the collision or responsibility for the accident is disputed.

Depending on the circumstances, relevant evidence may include:

• Police reports
• Photographs and videos
• Dashcam or surveillance footage
• Witness statements
• Truck inspection records
• Maintenance records
• Driver records
• Cargo-loading records
• Electronic vehicle data
• Medical records
• Medical bills
• Lost-income documentation

Electronic records may provide information about the truck and its operation before the crash. Our article on electronic evidence in truck crash claims explains why this evidence can be important.

Can You Still Get Compensation If You Were Partly at Fault?

California uses a comparative-fault system. If an injured person is found partly responsible for an accident, the amount of damages recovered can be reduced according to the percentage of fault assigned to that person.

For example, an insurance company may argue that the injured driver was speeding, following too closely, or otherwise contributed to the collision.

Whether that argument affects the claim depends on the facts and evidence.

Evidence showing what the truck driver, trucking company, or another potentially responsible party did before the crash can therefore become important when fault is disputed.

What Can You Recover After a Jackknife Truck Accident?

A serious truck accident can create financial and personal losses that continue long after the crash.

Depending on the circumstances, an injured person may seek compensation for:

• Medical expenses
• Future medical treatment
• Lost income
• Reduced earning capacity
• Physical pain
• Emotional distress
• Loss of enjoyment of life
• Other legally recoverable damages

The full impact of an injury may not be clear immediately. Some victims need continuing medical treatment or rehabilitation. Others may be unable to return to their previous job or may experience permanent changes to their daily lives.

For that reason, the value of a claim cannot always be determined from the first medical bill or an initial insurance offer.

What Happens After You File a Jackknife Truck Accident Claim?

A truck accident claim may be resolved through negotiations with an insurance company or through litigation when a fair resolution cannot be reached.

The circumstances of the claim may involve questions about:

• Liability
• The severity of the injuries
• Current and future medical expenses
• Lost income and earning capacity
• Pain and suffering
• Comparative fault
• Available insurance coverage
• The potential risks of litigation

A settlement reached before the full extent of an injury is understood may not account for future medical treatment or other losses.

Why Can Truck Accident Claims Be More Complicated Than Car Accident Claims?

A truck accident can involve more than the driver and the injured motorist.

The investigation may involve the trucking company, vehicle owner, maintenance providers, cargo handlers, insurers, and records connected to the truck and its operation.

There may also be more evidence to examine, including inspection records, maintenance information, driver records, cargo documentation, and electronic data.

That is why identifying responsibility in a jackknife crash can require a closer look at what happened before the collision, not just the damage left behind.

What Should You Know Before Accepting a Trucking Company’s Settlement?

An insurance company may make an offer before the full extent of your injuries and losses is known.

Before accepting a settlement, it is important to understand whether the offer accounts for:

• Current medical expenses
• Future medical care
• Lost income
• Reduced earning capacity
• Pain and suffering
• The long-term effects of the injury

Once a claim is settled, the injured person may have limited ability to seek additional compensation for the same losses.
