A jackknife truck crash can happen in seconds and leave a trail of severe injuries, damaged vehicles, and lives permanently altered. Jackknife truck accidents present a significant issue in Texas, particularly along major freight corridors such as I-10, I-20, I-30, I-35, I-40, and I-45. These highways link major metropolitan areas from El Paso to Austin to Houston over hundreds of miles.
The combination of heavy commercial traffic, high speeds, and varying weather conditions creates an environment where even a small mechanical problem or driving misjudgment can trigger a catastrophic chain reaction.
Jackknife truck accidents occur when the trailer of a large truck, such as a semi-truck or 18-wheeler, swings out at a sharp angle to the cab, creating the shape of a partially folded pocket knife. Once a truck jackknifes, the driver often loses control, and the trailer can block several lanes of traffic, endangering nearby vehicles.
The result is often a crash that leaves multiple vehicles damaged and victims coping with injuries ranging from broken bones to life-altering brain or spinal cord trauma—topics we will examine in depth throughout this blog. If you’ve been hurt in such a crash, an experienced Austin truck accident lawyer can help you pursue compensation and protect your rights.

Common Causes of Jackknife Truck Accidents in Texas
Jackknife truck accidents happen for a variety of reasons. While weather and road conditions sometimes play a role, most of these crashes stem from preventable human or mechanical factors.
Improper braking and sudden stops
Large trucks require far more stopping distance than passenger cars. If a truck driver brakes too hard or too suddenly, especially on wet, icy, or uneven pavement, the trailer can swing out, causing a jackknife accident. Improper braking techniques, such as locking the drive axles, reduce traction and make it easier for the trailer to push the cab sideways.
Brake failure or poorly adjusted brakes also raise the risk. Under Federal Motor Carrier Safety Administration (FMCSA) regulations, trucking companies have a legal duty to keep braking systems in safe working order. Still, inspections and maintenance are sometimes skipped under delivery pressure.
Excessive speed
Speeding increases the likelihood of a jackknife crash, particularly when a semi-truck is rounding a curve or traveling downhill. At high speeds, any sudden maneuver, like swerving to avoid another vehicle, can cause the trailer to swing into nearby lanes. Tight delivery schedules often encourage truck drivers to push the speed limit, even when traffic, weather, or road design make it unsafe.
Driver fatigue
Fatigue slows reaction time, impairs judgment, and increases the chance of driver error. Federal hours-of-service rules are designed to limit driving time, but violations are common in the trucking industry. Long shifts, tight deadlines, and inadequate rest periods can leave drivers dangerously tired behind the wheel.
Driver inattention
Distracted driving from using a cell phone, eating, adjusting in-cab systems, or engaging in another attention-grabbing activity can be equally dangerous. Even a few seconds of inattention can cause a driver to miss signs of hazards, leaving too little time to brake or steer safely.
Improperly loaded or shifting cargo
Cargo that isn’t properly secured can shift during transit, changing the trailer’s center of gravity and making it harder to control during braking or turning. Overloading a truck is equally risky, as the extra weight lengthens stopping distance and strains mechanical components. In Texas, state and federal weight limits aim to prevent this, but violations still occur.
Equipment failure and poor maintenance
Worn-out tires, defective coupling devices, and suspension issues can all contribute to jackknife accidents. A sudden blowout or loss of steering control can cause the driver to lose control of the trailer’s movement. Regular inspections under FMCSA rules are critical, but mechanical issues are still a frequent cause of serious crashes.
How Jackknife Truck Accidents Happen
When a jackknife occurs, the trailer’s momentum overpowers the cab’s direction of travel. This often happens when:
- The truck’s drive wheels lock while the trailer wheels keep moving.
- A sudden change in speed or direction causes the trailer to swing outward.
- Adverse weather, such as heavy rain or icy bridges, reduces traction.
- Improper braking or steering inputs trigger a skid that spreads to the trailer.
Once the trailer swings out, it can block multiple lanes, striking nearby vehicles and creating a chain-reaction collision. In some cases, large semi-trucks jackknife on rural Texas highways, where emergency response times can be longer, increasing the risk of severe outcomes.
Common Injuries in Jackknife Truck Accidents
Because semi-trucks and other large trucks weigh 20–30 times more than most passenger vehicles, the injuries from a jackknife crash can be devastating. Victims often need extensive medical treatment and face months or years of recovery.
Traumatic brain injuries (TBI)
A blow to the head or violent shaking during a collision can cause a TBI. These injuries range from concussions to severe brain damage and may lead to lasting problems with memory, balance, speech, and mood regulation.
Spinal cord injuries
Damage to the spinal cord can cause partial or complete paralysis. Even when paralysis does not occur, spinal injuries can leave victims with chronic pain, reduced mobility, and the need for ongoing medical care.
Broken bones and fractures
The force of impact in a jackknife crash can easily break bones in the arms, legs, ribs, or pelvis. Complex fractures may require surgery, hardware implants, and lengthy rehabilitation.
Internal injuries
Blunt force trauma can damage internal organs such as the liver, spleen, or kidneys. These injuries may not be immediately obvious, which is why immediate medical attention after a truck accident is essential.
Lacerations and soft tissue injuries
Flying debris, shattered glass, and metal fragments can cause deep cuts, torn muscles, and severe bruising. Even seemingly minor injuries can lead to complications if untreated.
Psychological trauma
Beyond physical injuries, survivors of jackknife crashes often experience post-traumatic stress disorder (PTSD), anxiety, and depression. These emotional injuries can be just as disruptive as physical harm and may require professional care.
Why Texas Roads See a High Risk for Jackknife Truck Accidents
Texas is home to some of the busiest trucking routes in the United States. The Lone Star State is also home to the most commercial truck accidents in the U.S. every year, far exceeding California and Florida, which consistently claimed the second and third spots. According to FMCSA crash data, 19,424 truck accidents occurred in Texas in one recent year, resulting in 692 deaths and 7,517 injuries.
Interstates like I-35, I-10, and I-45 are vital freight corridors connecting cities and ports, which means more large trucks share the road with passenger vehicles every day. Factors that heighten the risk include:
- Long stretches of rural highway where speeds are high
- Rapidly changing weather conditions, from heavy rain to sudden ice storms
- High volumes of interstate freight traffic under tight delivery deadlines
- Oilfield and agricultural transport adding to commercial truck volume
The combination of high speeds, heavy truck traffic, and variable weather makes jackknife truck accidents a year-round concern in Texas.
Steps to Take After a Jackknife Truck Accident in Texas
Commercial truck accidents often result in serious, life-altering injuries and death, leading to scores of injury claims and high-stakes truck accident lawsuits.
If you were injured by a negligent truck driver in a Texas jackknife accident, you may be planning to take legal action. If that’s the case, there are some important steps you can take to protect the value of your claim.
If you received emergency medical care for your injuries or are currently undergoing treatment, you’ve taken the first step. If you haven’t been checked out by a doctor yet, do it as soon as possible. Some serious conditions, such as internal bleeding or concussions, don’t always cause immediate symptoms but can worsen quickly without treatment. Beyond medical care, you should:
Hire a lawyer right away
Trucking companies and their insurers often begin investigating within hours of a crash. The sooner you have a lawyer on your side, the sooner critical evidence can be preserved, such as driver logbooks, dashcam footage, and electronic control module (ECM) data from the truck.
An experienced Texas truck accident attorney can communicate with the insurance companies on your behalf, investigate the cause of the crash, and start building a case for full and fair compensation.
Keep medical appointments and follow treatment plans
Missing appointments or ending treatment early can give insurers grounds to dispute your injuries. Attending all follow-ups, therapy sessions, and specialist visits supports both your recovery and your claim.
Document your recovery
Keep a written or video journal of your symptoms, mobility issues, and emotional challenges. This creates valuable evidence of how the accident affects your daily life.
Save all records and receipts
Hold onto medical bills, prescription receipts, proof of lost income, and costs for transportation or adaptive equipment. These help establish the full financial impact of the crash.
Limit insurance company contact
Insurers aim to minimize payouts. Direct all communications to your attorney and avoid giving recorded statements without legal advice.
Federal and Texas Laws That Can Affect Your Claim
Several laws and regulations are especially important in jackknife truck accident cases.
- Federal Motor Carrier Safety Regulations (FMCSRs): These set standards for driver hours, maintenance, cargo securement, and vehicle safety equipment.
- Texas Transportation Code Chapter 644: Incorporates many FMCSRs into state law, meaning violations can support a negligence claim. This means if a trucking company or driver breaks these safety rules, such as exceeding hours-of-service limits or failing required maintenance, it can be used as evidence they breached their legal duty to operate safely.
- Texas comparative fault rule (Tex. Civ. Prac. & Rem. Code § 33.001): Allows recovery even if you are partially at fault, but your damages may be reduced by your percentage of fault. For instance, if you’re found to be 20% at fault for the accident, your total compensation would be reduced by 20%.
Knowing whether the truck driver or the trucking company violated these rules makes a significant difference in your case.
Who Can Be Held Liable in a Jackknife Truck Accident?
Determining liability in a jackknife crash often requires a detailed investigation. Potentially responsible parties may include:
- The truck driver for unsafe driving, hours-of-service violations, or distracted driving
- The trucking company for negligent hiring, improper training, or failing to maintain the vehicle
- Cargo loaders for unbalanced or unsecured freight
- Manufacturers or maintenance contractors for defective or poorly repaired brakes, tires, or coupling systems
Multiple parties can share liability, and each may have separate insurance coverage, which can make the claims process more complex and increase the importance of a thorough investigation.
Long-Term Challenges Victims Face
Recovering from a jackknife truck accident can take months or years. Common ongoing challenges include:
- Chronic pain from orthopedic or spinal injuries
- Reduced mobility or permanent disability
- Need for ongoing medical care, physical therapy, or adaptive devices
- Loss of income or career changes due to physical limitations
- Emotional effects such as PTSD, anxiety, or depression
Because these injuries often require future care, settlement negotiations must factor in not only current losses but also projected costs.
FAQs About Jackknife Truck Accidents in Texas
How long do I have to file a lawsuit after a jackknife truck accident in Texas?
Under the Texas statute of limitations (Tex. Civ. Prac. & Rem. Code § 16.003), you generally have two years from the date of the accident to file a personal injury lawsuit. Certain exceptions may shorten or extend this period, so it’s best to consult a lawyer promptly.
What if I was partly to blame for the crash?
Texas follows a modified comparative fault rule. You can still recover damages if you were less than 51% at fault, but your recovery will be reduced in proportion to your share of responsibility.
Are truck drivers in Texas required to have special training to avoid jackknife accidents?
Yes. Commercial driver’s license (CDL) training includes instruction on braking techniques, handling adverse weather, and cargo securement. Failure to follow this training can be used as evidence of negligence.
Can weather alone cause a jackknife crash?
Adverse weather like rain, ice, or high winds can contribute, but drivers are required to adjust their speed and driving style to match road conditions. If they fail to do so, they may still be held liable.
How much does it cost to hire a Texas truck accident lawyer?
Most personal injury attorneys, including truck accident lawyers, work on a contingency fee basis. This means you pay no upfront fees, and the lawyer only collects if they obtain a settlement or verdict for you.
How a Texas Truck Accident Lawyer Can Help After a Jackknife Crash
The trucking industry is heavily regulated, and any violations of safety rules can strengthen a personal injury claim. However, trucking companies and their insurers often have teams of lawyers and adjusters working to limit payouts, making it important to have legal representation on your side.
Evidence can be lost or destroyed quickly, especially driver logs, electronic control module (ECM) data, and surveillance video. Working with a lawyer from the start means:
- Evidence is preserved and investigated before it disappears.
- All liable parties are identified, including those behind the scenes.
- Negotiations include full accounting for future costs, not just immediate bills.
- You have someone experienced in standing up to large trucking companies and insurance carriers.
