Jackknife Truck Accident: All You Need To Know

Jackknife truck accidents are fairly common, but they can lead to deadly consequences. A jackknifed truck can block some or all lanes of traffic, causing other vehicles to collide with the truck. These collisions can sometimes cause a domino effect which causes secondary accidents, or pile-ups. 

What Is Jackknifing? What Does the Term Jackknife Mean?

Jackknifing occurs when a trailer swings out and folds over the cab, creating a sharp angle resembling a jackknife. This typically happens when a driver loses control of a semi-truck and suddenly brakes.

The severity of jackknife accidents is amplified by the size and weight of semi-trucks, which can weigh up to 80,000 lbs. Understanding the risks and taking precautions is crucial to reducing the frequency of jackknife incidents.

Why Do Semi-Trucks Frequently Jackknife?

One of the most common causes of jackknife truck accidents is improper braking. Large trucks take longer to stop, especially when fully loaded. 

Other common causes include:

  • Equipment failure. Faulty brakes or tire blowouts can lead to lost control.
  • Adverse road conditions. Weather, steep inclines, and poorly maintained roads make stopping difficult.
  • Driver error. Fatigue, inexperience, and high speeds increase the risk of accidents.
  • Improper loading. Unbalanced cargo can destabilize the truck and cause jackknifing.

These factors can often combine, heightening the risk of a jackknife accident.

What Damage Can a Jackknife Truck Accident Cause?

Jackknife truck accidents often happen on highways, causing extensive damage and even fatalities. Data from the National Security Council shows an increase in truck accidents over recent years, with jackknife accidents accounting for around 10% of fatal crashes involving large trucks.

Damages can include:

  • Severe injuries to drivers and passengers.
  • Traffic delays and additional collisions.
  • Extensive property damage.

The massive weight of trucks makes these accidents particularly dangerous and costly.

What Should I Do if You’re the Victim of a Jackknife Collision?

If you are involved in a jackknife truck accident and uninjured, follow these steps:

  1. Turn on hazard lights and move to a safe location if possible.
  2. Check for injuries and ensure everyone’s safety.
  3. Call the police and make an official report.
  4. Make sure to avoid making statements that may indicate your fault.

After everyone is safe and law enforcement is called, gather evidence, including witness information. Take photos and videos of the accident, road conditions, and vehicle damage. Having sufficient evidence can help prove your case. Most importantly, the driver’s details, including the license plate, USDOT number, and company branding, must be obtained. 

What To Do if You Were Injured In a Jackknifing Truck Accident

If injured in a jackknife accident:

  • Seek medical attention. Even minor symptoms may indicate serious injuries.
  • Notify your insurance company. Report the accident without providing detailed statements.
  • Document everything. Keep records of medical bills, repair costs, lost wages, and other expenses.

Once it is safe to do so, consult an attorney. Accidents often involve multiple parties, such as the driver, trucking company, and manufacturer. Legal assistance can help establish liability and preserve evidence.

How To Avoid a Jackknife Truck Accident

While you can’t control other drivers, these steps can reduce your risk:

  • Maintain a safe distance and give trucks ample space, especially when stopping.
  • Avoid sudden lane changes, anticipate truck movements, and drive predictably.
  • Be cautious when passing, and ensure there is enough space.
  • Reduce speed and increase following distance in bad weather and hazardous conditions.
  • Avoid sudden stops to prevent startling truck drivers with abrupt braking.

Staying alert and driving defensively can help prevent accidents.

How Much Compensation Could You Receive From A Jackknife Accident?

Compensation depends on several factors, such as the accident’s severity and impact on your life. 

You may be entitled to:

Each case is unique. Consulting an attorney can help determine the compensation you deserve.

It’s normal to feel overwhelmed when dealing with insurance companies to make sure you get a fair settlement. Jackknife truck accidents are serious, and you might need an experienced truck accident lawyer to look into the accident, find out who is at fault, and represent you in court if needed.
