Common Causes of Jackknife and Underride Truck Accidents in Missouri
Quick answer: Jackknife truck accidents and underride truck accidents on Missouri highways are mainly caused by sudden braking, slick weather conditions, and shifting or unbalanced cargo loads. These crashes often lead to severe injuries and fatalities for people in passenger vehicles.
Missouri highways like I-70 carry heavy truck traffic every day, and when something goes wrong with a large commercial truck, the results can be devastating. Two of the most dangerous types of crashes are jackknife accidents and underride accidents. Both put drivers and passengers in smaller vehicles at serious risk of injury or death.
Knowing what causes these accidents can help you stay alert and safer on the road. Labovitz Law Firm will explain how jackknife truck accidents and underride truck accidents happen, and what you can do if you or a loved one has been hurt in one.
What Causes Jackknife Truck Accidents in Missouri?
A jackknife accident happens when a truck’s trailer swings outward and folds into the cab, much like a pocketknife closing. The trailer ends up at a sharp angle to the tractor, often sliding across multiple lanes. Here are the most common causes.
1. Sudden Braking
Slamming on the brakes on slick roads can cause the trailer wheels to lock while the cab keeps moving forward. This mismatch throws the trailer out of line and sends it swinging sideways.
2. Speeding
Driving too fast for conditions makes it hard to safely navigate sharp curves or slow down in heavy traffic. Excessive speed reduces a driver’s ability to react, raising the risk of a jackknife.
3. Weather Hazards
Rain, ice, and snow on major corridors like I-70 reduce tire traction and grip. Missouri winters and sudden storms create slick surfaces that make trailers far harder to control.
4. Imbalanced Cargo
Unsecured freight can shift and destabilize the trailer during turns or stops. A load that moves at the wrong moment can push the trailer out of alignment and trigger a jackknife.
5. Equipment Failure
Worn brakes or broken anti-lock braking systems (ABS) prevent synchronized stopping. When the brakes on the cab and trailer don’t work together, the trailer can slide and fold.
What Causes Underride Truck Accidents in Missouri?
An underride crash happens when a smaller passenger vehicle slides underneath the side or rear of a semi-trailer. These accidents are especially deadly because the point of impact often hits the windshield and passenger area directly. Here are the main causes.
6. Abrupt Stops
A truck stopping suddenly without enough warning gives trailing drivers zero time to react. The car behind may not be able to brake before sliding beneath the trailer.
7. Low Visibility
Heavy fog, rain, or unlit trailers at night make trailers hard to see. A driver who spots a trailer too late has little chance of avoiding an underride crash.
8. Jackknifed Trailers
A truck that has already jackknifed blocks multiple lanes, creating a sudden barrier that cars slide beneath. This is one reason jackknife truck accidents and underride truck accidents are so closely linked.
9. Missing or Broken Underride Guards
Damaged or weak rear and side guards fail to stop a car from penetrating the trailer space. When these guards are missing or poorly maintained, the protection they should provide disappears.

Frequently Asked Questions
What Is the Difference Between a Jackknife and an Underride Truck Accident?
A jackknife accident occurs when a truck’s trailer swings out and folds toward the cab, often sliding across lanes. An underride accident occurs when a smaller vehicle slides underneath the side or rear of a semi-trailer. A jackknifed trailer can also lead to an underride crash when it blocks the road.
Why Are Underride Truck Accidents So Dangerous?
Underride crashes are dangerous because the smaller vehicle slides beneath the trailer, so the impact often strikes the windshield and passenger compartment directly. This can cause severe head injuries and fatalities even at lower speeds.
What Should I Do After a Truck Accident in Missouri?
Seek medical attention right away, report the crash to the police, and gather any available evidence such as photos and witness contact information. Then contact a Missouri truck accident law firm like Labovitz Law Firm to protect your rights and pursue compensation.
Can I Recover Compensation After a Jackknife or Underride Accident?
Yes. If another party’s negligence, such as a truck driver, trucking company, or cargo loader, contributed to the crash, you may be able to recover compensation for medical costs, lost wages, and pain and suffering. Labovitz Law Firm can help you evaluate your claim.
