Jackknife accidents in Missouri are a serious threat on highways, often causing chaos across multiple lanes. These crashes happen when a tractor-trailer swings out of alignment, causing the trailer to skid and swerve alongside or ahead of the cab.
Unlike regular truck accidents in St. Louis, jackknife events can pose even greater danger because the cab swings across multiple lanes, potentially affecting many cars. For anyone hurt or dealing with property loss from this kind of crash, it’s important to know what to do and how you can pursue compensation.
Common Causes of Jackknife Accidents in Missouri
Jackknife accidents are dramatic events that often result from a particular combination of conditions or mistakes on Missouri roads. Understanding why they occur can help jackknife truck accident victims pinpoint responsibility and prevent similar crashes in the future.
Sudden Braking
Abrupt braking, especially at high speeds, is a well-known cause of jackknifing. When a semi-truck’s driver hits the brakes hard, the drive wheels may lock while the attached trailer keeps moving forward with momentum. This difference in motion pushes the trailer to swing out, folding it onto itself.
Improperly Loaded or Unbalanced Cargo
When a trailer’s weight isn’t evenly distributed or when heavy cargo isn’t properly secured, even standard braking or turning can send uneven force through the trailer. This increases the likelihood that the trailer will swing wildly, eventually causing the entire vehicle to fold into a jackknife.
Poor Weather and Slick Road Conditions
Rain, ice, snow, or even wet leaves in the fall reduce the friction needed for a large commercial truck to operate as intended. Since the trailer is much heavier and doesn’t have the drive axle traction of the cab, it can easily begin sliding during quick stops or tight corners on Missouri roads.
Equipment Issues (Brakes, Tires)
Worn or poorly maintained brakes, failing anti-lock brake systems (ABS), or slick tires mean the truck can’t respond as the driver expects. These issues can cause the trailer to move faster than it should relative to the truck, leading to a jackknife.
If you’re dealing with the aftermath, figuring out the cause can make a difference when you’re trying to obtain compensation.
Evidence Needed in a Jackknife Accident Case
If you’ve been injured in a jackknife accident and believe someone else was at fault, collecting the right evidence is crucial for proving your truck accident claim in St. Louis and getting fair compensation. The more complete and compelling the documents and records, the stronger your case will be. Some of the most important types of evidence include the following:
Police and Crash Reports
When police arrive at the scene of the crash, they’ll create an accident report detailing what they see. This will include who is involved in the crash, what the scene is like, and who they think might be at fault. They’ll also include whether anyone was cited for traffic violations. This can be a big part of your case.
Truck Data and Electronic Logging Devices (ELDs)
Modern trucks carry built-in computers that record speed, braking patterns, location, difficult driving maneuvers, and how long the truck has been operating without rest. These readouts can provide evidence of what was going on before and during the accident, as well as whether hours-of-service regulations were ignored. ELD data is hard for companies to contest, making it an important part of your claim.
Maintenance and Inspection Records
Evidence that a truck wasn’t properly maintained can also be used in your case. Looking at how the truck was taken care of right before the accident and how that could have played a role in the crash is critical.
Driver Logs and Training Records
Looking at a driver’s break schedule, their training history, and any past crashes or disciplinary problems can reveal if something was missed. If it turns out the driver or the company disregarded FMCSA regulations, or skipped necessary training, that’s strong evidence pointing to negligence.
Accident Reconstruction Evidence
Specialists use photos, roadway measurements, witness accounts, and even simulation programs to recreate exactly how and why the crash occurred. If an expert can explain why the accident occurred, it becomes easier for your lawyer to argue about who was responsible.
