What Causes Jackknife Accidents in Pennsylvania?
Jackknife accidents occur when the cab and trailer of a truck move separately from one another. This causes the trailer to pivot and swing out and around until both parts are folded in on themselves rather than staying in a straight line. As the truck pivots, it creates a sharp angle and reduces the truck driver’s leverage. In most jackknife accidents, something may trigger the cab or trailer’s tires to lock up, forcing one part of the truck to lose momentum before the other.
Several factors can contribute to these situations and result in serious or catastrophic accidents. When a truck jackknifes, vehicles in its path can sustain serious harm. This is especially true since a truck’s trailer can cross many lanes of traffic at once as it swings outward.
While the Pennsylvania Department of Transportation Crash Facts & Statistics report doesn’t specify the types of large truck crashes, it reported 7,312 heavy trucks were involved in accidents in 2024, some of which were likely jackknife accidents.
Some common causes of jackknife accidents include:
- Speeding
- Taking curves too fast
- Braking at high speeds on curves
- Blind spots
- Cargo overload or imbalance
- Empty trailers
- Faulty equipment
- Tire blowouts
- Road and weather conditions
- Poorly trained or inexperienced drivers
- Inadequate safety inspections
- Driver fatigue
To determine the exact cause of an accident, your Pennsylvania jackknife truck accident attorney will need to conduct a thorough investigation. The cause of the accident can make a considerable difference in who is at fault, how your case is resolved, and how much you may be able to recover. Collecting and preserving all relevant forms of evidence is crucial for determining the cause of the accident.
How Is Liability Proven in a Pennsylvania Jackknife Truck Accident Case?
Determining liability in a jackknife accident is essential, but it can be a very complex and challenging process. While the fault may lie with the driver since they are responsible for driving safely and retaining control of their truck, they may not always be the reason the jackknife incident occurred. Getting to the heart of an accident may require some in-depth probing, all of which your Pennsylvania jackknife truck accident lawyer can do on your behalf.
The Four Elements of Liability in a Jackknife Accident Case
The other parties who may share liability in a jackknife accident include the trucking company, maintenance technicians, cargo loaders, manufacturers, government entities, and motorists. Any of these parties can be held liable if they are found to have been negligent in their duties. This aspect must be shown in your case to resolve it. This involves showing four facets of negligent behavior:
- Duty of care: All the parties mentioned above have their own respective responsibilities to secure safety and protect others from harm.
- Breach of duty: Any one of the applicable parties failed to uphold their responsibilities and was careless in their duties.
- Causation: The carelessness of one of these parties contributed to the cause of the jackknife accident that led to injuries and losses.
- Damages: The at-fault party is liable for compensating the victim for their injuries and suffering.
Your lawyer will work with you to collect the necessary evidence to demonstrate each element of negligence. Documentation is essential for supporting your claim and holding the other party accountable. Based on the available evidence and the details of your specific situation, your lawyer will determine the most effective strategy to use when building your case. Every case is different, and they will adjust their approach as needed to get you maximum results.
What Injuries Are Common in Pennsylvania Jackknife Truck Accidents?
Sadly, vehicles can end up in the path of a trailer when it jackknifes, and occupants can suffer serious injuries. Tractor-trailers are large and may be fully loaded when this type of accident occurs, intensifying the force of the impact upon collision. Large trucks have a higher center of gravity, which can make it more challenging for truck drivers to maintain control. They may flip or roll over as a result of jackknifing, which can injure both the driver and the motorist in the following ways.
Traumatic Brain Injuries
Traumatic brain injuries can occur as a result of a jackknife accident. The force of the collision can throw occupants against the vehicle’s interior, causing them to hit their head. Head trauma can cause a traumatic brain injury. These severe conditions can cause individuals to suffer physical, cognitive, sensory, behavioral, and psychological symptoms and challenges. These injuries may improve over time, have residual effects, or cause irreparable harm or death.
Spinal Injuries
Given the considerable force a small vehicle can sustain when a tractor-trailer slams into it, the spine may suffer greater impact than it can handle. This can affect the vertebrae, discs, and nerves in the spine, disrupting its normal functioning. With a spinal cord injury, victims may lose control over various functions in the body and may even become paralyzed. Damage to the spine can entirely or partially sever its power and ability to communicate with the brain.
Internal Injuries
Not all injuries are externally visible, and internal bleeding and organ damage are one such example of this. Even bleeding in the brain can occur depending on the situation. These types of conditions can most effectively be identified through medical testing and the trained eye of a medical professional. If left untreated, internal bleeding could be fatal. The impact of a jackknife accident is capable of causing this kind of trauma to the body and requires a swift response.
Catastrophic Injuries
A catastrophic injury is any injury that causes permanent and irreparable harm. A few examples of these types of injuries include:
- Paralysis
- Loss of limb or amputation
- Burns
- Loss of vision or hearing
Not only do catastrophic injuries require a considerable amount of medical care, but they may also require assistive equipment and technologies, home or vehicle accommodations, or long-term care. Jackknife accidents are capable of causing these types of injuries.
Wrongful Death
In some cases, a jackknife accident can be so severe that it results in one or more deaths. In 2021, the Federal Motor Carrier Safety Administration (FMCSA), recorded 5,700 fatal accidents caused by large trucks jackknifing. The weight and force of the truck can destroy or crush a smaller vehicle. Vehicles may also become entangled in the truck’s underride, which can be deadly due to the higher point of impact.
What Types of Compensation are Available in Jackknife Truck Accident Cases?
If you have been involved in a jackknife accident, there is a good chance you have suffered severe injuries that require extensive medical care. This can result in enormous expenses that can have a domino effect on the rest of your life. Damages provide a holistic approach to help you recover your losses. It typically covers your financial losses and any losses related to trauma. Compensation typically covers the following:
- Medical and rehabilitative expenses
- Cost of rehabilitation, equipment, home and vehicle accommodations, and medications
- Loss of income or earning capacity
- Cost to repair or replace your vehicle and personal belongings
- End-of-life, funeral, and burial expenses when death occurs as a result of the accident
- Loss of services or inheritance
- Pain and suffering caused by the collision
- Emotional distress
- PTSD, anxiety, depression, and insomnia
- Reduced quality of life and ability to enjoy activities you did before
- Loss of companionship or consortium

We determine how much your case is worth based on a variety of factors and negotiate a settlement that fairly compensates you.

What Does Role Pennsylvania’s Modified Comparative Negligence Law Play in Liability and Compensation?
If, for some reason, you are partially at fault for triggering a jackknife accident, it is important to hire a lawyer immediately. While you may still be able to recover compensation, your lawyer will need to work to limit your liability in the accident to secure you a more favorable outcome. They can optimize your case so you can still receive damages per Pennsylvania’s modified comparative negligence rule, 42 Pa. C.S.A. § 7102.
This law states that compensation can be recovered if you are less than 50% at fault for the accident. Your total settlement value will be reduced in proportion to the amount of fault you contributed. However, it is important to note that fault percentages above the 50% threshold are prohibited from claiming compensation.
Frequently Asked Questions about Jackknife Truck Accident Cases
What Should I Do Immediately After a Jackknife Truck Accident in Pennsylvania?
Immediately after you’re involved in a jackknife truck accident in Pennsylvania, you should prioritize your safety and seek medical attention, even if your injuries seem minor. Call 911 to report the accident. Next, take photos of the scene and your injuries, gather the names and contact details of witnesses, and, if possible, the truck driver’s details.

Are Jackknife Truck Accidents More Common with Empty Trailers?
Yes. Empty trailers can be more difficult to control because they have less weight to stabilize the rear of the truck. This increases the likelihood of trailer swing and loss of traction during sudden braking or sharp turns.
Drivers transporting empty trailers must adjust their driving behavior to account for these risks. Improper handling can quickly lead to a jackknife situation.
Can a Defective Truck Part Cause a Jackknife Accident?
Defective brakes, tires, steering systems, or trailer couplings can contribute to a jackknife accident. In some cases, manufacturers or maintenance companies may share liability if defective equipment caused the driver to lose control of the vehicle.
Product liability investigations may involve engineers, mechanical inspections, and maintenance histories. Identifying all responsible parties can increase the compensation available to victims.
Who Can Be Held Liable for a Jackknife Truck Accident?
Several parties can be held liable for a jackknife truck accident. Depending on the cause, responsibility may fall on the truck driver, trucking company, maintenance crews, cargo loaders, parts manufacturers, or government entities responsible for road conditions. Your Munley Law lawyer will conduct a thorough investigation to determine who breached their duty of care and will build a strong case showing how their negligence caused your injuries and losses.
