Des Moines Jackknife Truck Accident Lawyers

A fully loaded tractor-trailer can weigh 20 times as much as your car. When its trailer swings out of line and folds toward the cab, it can sweep across several lanes of a Des Moines interstate in seconds. If that happened to you, you were likely hurt through no fault of your own, and you are probably facing medical bills, time away from work, and a trucking company that is already protecting itself.

A jackknife truck accident lawyer can investigate what caused the trailer to lose its line and hold the responsible parties accountable. At MSMC Injury Lawyers, our truck accident lawyers help injured Iowans deal with the trucking company and its insurer so they can focus on getting better. If you have questions about your options, you can contact MSMC Injury Lawyers for a free consultation.

What Is a Jackknife Truck Accident?

A jackknife happens when a truck’s trailer swings out from behind the cab and folds toward it, forming a shape like a partly closed pocketknife. The cab and trailer end up at a sharp angle, often an L or a V, and the trailer can slide sideways across the road.

These crashes are dangerous because of where and how fast they happen. On high-speed routes like Interstate 80, Interstate 35, and the Interstate 235 loop through central Des Moines, a sliding trailer can cover multiple lanes before it stops, giving nearby drivers little time to react.

Once a trailer breaks loose from the line of travel, the driver has limited control over where it goes. The truck can strike several vehicles at once, and the people in the smallest vehicles usually suffer the worst injuries.

What Causes a Truck to Jackknife?

A jackknife can result from driver actions, vehicle problems, road conditions, or a combination of factors. Common causes include:

• Hard or Sudden Braking: Slamming the brakes can lock the trailer’s wheels and let the trailer swing out faster than the cab.
• Driving Too Fast for Conditions: A loaded truck needs far more room to stop, and speed leaves the driver no margin when traffic slows, or a curve tightens.
• Slick or Icy Roads: Iowa winters, freezing rain, and sudden storms reduce traction, and a truck that brakes on a slick surface can jackknife.
• Steep Grades and Tight Ramps: Downhill stretches and interstate exit ramps put extra force on the trailer, especially when a driver brakes late.
• Improper Braking Technique: Braking through a turn or using the wrong method for the load can start the trailer sliding.

Equipment failure is its own category. Worn brakes, bald or defective tires, and faulty trailer or coupling parts can trigger a jackknife even when the driver does everything right. When that happens, responsibility can fall on the trucking company that skipped maintenance or the maker of a defective part.

Our Des Moines truck accident lawyers closely review maintenance and inspection records to determine whether a mechanical problem played a role.

FMCSA Regulations and Jackknife Prevention

Trucking companies and their drivers follow more than Iowa traffic laws. Most are also subject to federal motor carrier safety rules. Federal Motor Carrier Safety Administration (FMCSA) rules exist to prevent many of the conditions that lead to a jackknife.

FMCSA rules require carriers to keep brakes inspected and in working order, remove unsafe trucks from service, and limit how many hours a driver can stay behind the wheel before resting. A carrier that ignores a brake problem, skips a required inspection, or pushes a tired driver to meet a delivery window sets up a trailer to slide.

When one of these violations contributes to a jackknife, the violation can serve as evidence of negligence. Part of building your claim is pulling the maintenance logs, inspection records, and hours-of-service data. The sooner you talk to our team, the sooner we can request that evidence before it disappears.

Who Is Liable for a Jackknife Truck Accident?

Liability in a jackknife crash often reaches beyond the driver. Depending on what caused the trailer to lose its line, more than one party may share responsibility:

• The Trucking Company: Carriers must maintain their trucks, train their drivers, and set reasonable schedules. Cutting corners on any of these can make the company liable.
• A Maintenance or Repair Provider: If a shop did negligent work on the brakes or another critical system, it may share fault for a failure on the road.
• A Cargo Loader: Overloaded or poorly secured freight can shift and throw a trailer out of balance. The loading company may be responsible.
• A Parts Manufacturer: When a defective brake component or tire fails, the maker of that part can be held accountable.

Finding every responsible party matters because it affects how much compensation is available. Trucking cases involve commercial insurance policies and corporate defendants with their own investigators, so you must gather and preserve evidence quickly.

If you drive a truck for a living and were hurt because of a defect or a maintenance failure you did not cause, you may have options too. Depending on the situation, an injured driver can sometimes bring a workers’ compensation claim, a claim against a third party such as a parts manufacturer or a negligent repair shop, or both.

Common Injuries in a Jackknife Truck Crash

Because a jackknife can throw a trailer across several lanes at highway speed, the injuries tend to be serious. People in smaller vehicles absorb the force of a much heavier truck. Common injuries include:

• Whiplash and Neck Injuries: The violent motion of a collision can strain or tear the soft tissue in the neck and back.
• Spinal Cord Injuries: Spine damage can cause lasting pain, limited movement, or paralysis.
• Traumatic Brain Injuries: A blow to the head can cause a concussion or a more severe traumatic brain injury that affects memory, mood, and daily function.
• Broken Bones: The force of a truck collision often fractures arms, legs, ribs, and hips.
• Internal Injuries: Blunt force can damage organs and cause internal bleeding that is not always obvious right away.

Severe crashes send people to Des Moines trauma centers like MercyOne Des Moines and UnityPoint Iowa Methodist, and the medical bills add up fast. When a jackknife takes a life, the family left behind may be able to pursue a wrongful death claim through the estate to seek accountability and support for their loss.

Injured as a Passenger in a Jackknife Accident?

Passengers hurt in a jackknife crash have the same right to seek compensation as drivers. Whether you were riding in a car the trailer struck or in the truck itself, you may have a claim against the at-fault driver, the trucking company, or more than one party.

A few steps protect both your health and your claim after a crash:

• Get Medical Care Right Away: Some injuries, including brain and internal injuries, do not show symptoms at first. A prompt exam protects your health and documents what happened.
• Keep Your Records: Hold on to medical bills, the crash report, and anything related to your injuries and expenses.
• Be Careful With the Insurer: The trucking company’s insurance representative may call quickly. You do not have to give a recorded statement or accept an early offer before you understand what your claim is worth.

You didn’t choose this situation, and you shouldn’t have to sort it out alone. An experienced attorney can deal with the insurer while you recover.

Iowa’s Deadline and Fault Rules for Truck Accident Claims

Two Iowa law rules shape almost every truck accident claim in Des Moines.

The first is the deadline. Under Iowa Code Section 614.1(2), you generally have two years from the date of the crash to file a personal injury lawsuit. Miss that window, and the court can throw out your case no matter how strong it is. Some situations shorten or change the deadline, so it is smart to act well before the two years run out.

The second is the fault rule. Iowa follows modified comparative fault under Iowa Code Section 668.3. You may still recover as long as you are not found more at fault than everyone else combined, which in most crashes means you cannot be more than 50 percent at fault.

If you share some blame, your compensation is reduced by your percentage of fault. Insurers know this rule and often try to shift blame onto you, so building your side of the story matters.

Who Can Be Held Liable for a Jackknife Truck Accident in Iowa?

Liability can extend beyond the truck driver to the trucking company, a maintenance provider, a cargo loader, or the maker of a defective part. Identifying everyone at fault can affect how much compensation you can receive for your injuries.

What Are the Common Injuries in a Jackknife Truck Crash?

Get medical attention right away, then keep records of your injuries and expenses. Be cautious about giving a recorded statement to the trucking company’s insurer before you understand your rights.

Can a Truck Driver File a Claim After a Jackknife Caused by Equipment Failure?

It is possible. A driver hurt because of a defective part or a maintenance failure they did not cause may be able to bring a workers’ compensation claim, a claim against a third party such as a parts manufacturer or a repair shop, or both. The right path depends on the facts, so it helps to have an attorney review what happened.

How Long Do I Have to File a Truck Accident Claim in Iowa?

Under Iowa Code Section 614.1(2), you generally have two years from the date of the crash to file a personal injury lawsuit. Certain circumstances can change that deadline, so it is wise to speak with a lawyer well before it runs out.

What Evidence Matters Most in a Jackknife Truck Accident Case?

The most important evidence usually includes the truck’s black box and electronic logging device data, the driver’s hours-of-service logs, and the carrier’s maintenance and inspection records. The trucking company controls much of it, and it can be lost if it isn’t preserved quickly.
