Eisenberg Law Offices, S.C. | January 13, 2026 | Truck Accidents
Large trucks are common on Madison roads, from the Beltline to Interstate 39 and Interstate 90. When something goes wrong, these vehicles can cause serious harm. One of the most dangerous types of truck crashes is a jackknife accident. If you or a loved one has been hurt, understanding what happened and what to do next can make a stressful situation feel more manageable.
Below is a clear guide to jackknife truck accidents and why they are so dangerous.
A jackknife accident happens when a truck’s trailer swings out to the side, forming an “L” or “V” shape with the cab. This folding motion looks like a pocketknife closing, which is how the crash gets its name.
Once a truck jackknifes, the driver often loses control. The trailer can block multiple lanes of traffic or slide into nearby vehicles. Because of a truck’s size and weight, these crashes often cause severe injuries and significant property damage.
Jackknife accidents are especially dangerous because they involve large, heavy vehicles moving at high speeds. When a trailer swings sideways, it can:
Passenger vehicles offer little protection against a fully loaded semi-truck. Even a low-speed jackknife can lead to serious harm.
Jackknife accidents rarely happen for just one reason. In many cases, several factors combine to cause the crash.
Hard braking is one of the most common causes of accidents. If a truck driver slams on the brakes, the wheels can lock up. When the cab slows faster than the trailer, the trailer may swing out of line.
Snow, ice, rain, and slush are common in Wisconsin. Slippery roads make it harder for truck drivers to stop safely. Even experienced drivers can lose control if conditions suddenly change.
A truck does not need to be speeding to be unsafe. Driving too fast for traffic, weather, or road conditions increases the risk of jackknifing, especially when braking or turning.
Cargo that is unbalanced or improperly secured can shift while the truck is in motion. This makes the trailer harder to control and more likely to swing out during braking.
Worn brakes, tire issues, or faulty safety systems can also play a role. Trucks require regular inspection and maintenance, and failures can have serious consequences.
Jackknife truck accidents can happen anywhere, but they are more common in areas with heavy traffic or sudden stops. In and around Madison, this may include:
Winter weather increases the risk on both highways and local roads.
Because jackknife crashes often involve high force, injuries are frequently severe. Victims may suffer:
Recovery can take weeks, months, or longer. Some people are left with permanent limitations that affect their ability to work and enjoy daily life.
The moments immediately following a truck accident can be overwhelming. Taking a few basic steps can help protect your health and your rights.
First, call 911 and seek medical attention, even if you think your injuries are minor. Some injuries take time to show symptoms.
If you are able, gather information at the scene. This may include photos of the vehicles, road conditions, and any injuries you sustained. Get contact details from witnesses if possible.
Avoid discussing fault at the scene or giving detailed statements to insurance companies before you understand your situation. What you say early on can be misunderstood or used against you later.
Truck accident cases are often more complex than typical car crashes. Depending on the facts, responsibility may fall upon:
More than one party may share responsibility. Identifying all involved parties is a crucial step in determining your legal options.
Trucking companies and their insurers often respond quickly after a crash. They may have teams working to limit their financial exposure. Evidence such as driver logs, maintenance records, and onboard data can be critical, but it may not be preserved for future reference.
As a result, it is beneficial to act promptly after a serious truck accident.
Jackknife truck accidents can change lives in an instant. If you were injured in a jackknife crash in Madison or the surrounding area, you do not have to face the aftermath alone.
