Jackknife Truck Accidents: All You Need to Know

Every year, thousands of truck accidents occur on Florida roads, many of which result in serious injuries and fatalities. Among the most dangerous and dramatic of these are jackknife accidents. A jackknife truck accident happens when a large truck (typically an 18-wheeler) folds in on itself at the point where the cab meets the trailer, forming an L or V shape. 

These types of accidents often lead to multi-vehicle collisions, highway closures, and life-altering consequences for victims. If you or a loved one has been involved in a jackknife truck accident, understanding your legal rights and options under Florida personal injury law is crucial.

What Is a Jackknife Truck Accident?

A jackknife accident refers to an incident where a truck’s trailer swings outward and forms an angle with the cab. This movement resembles the folding of a pocket knife, hence the term “jackknife.” These accidents typically occur when the trailer skids and pivots due to a loss of traction, causing the driver to lose control. 

Because of the size and weight of commercial trucks, jackknife accidents often block multiple lanes of traffic and can involve multiple other vehicles. The risk of severe injuries, property damage, and even fatalities is significantly higher compared to typical car accidents.

Common Causes of Jackknife Accidents in Florida

Several factors can contribute to a jackknife truck accident:

  • Sudden braking or speeding: When truck drivers brake suddenly, especially on wet or slippery roads, the trailer can slide out of alignment. Florida’s wet weather and sudden storms often contribute to this condition.
  • Poor weather conditions: Florida drivers are no strangers to sudden downpours. Rain, fog, and even hurricanes reduce traction and visibility, increasing the likelihood of jackknife events.
  • Improper loading: Uneven or overloaded trailers can destabilize the truck and increase the chance of jackknifing during turns or sudden stops.
  • Driver fatigue or error: Truck drivers often work long hours under tight deadlines. Fatigue and lack of focus can result in overcorrection, sudden maneuvers, or failing to adjust speed—all of which can trigger a jackknife accident.
  • Mechanical failures: Brake malfunctions or worn tires are common causes of accidents. 

To avoid such an accident, always try to maintain safe driving conditions. 

Determining who is liable in a jackknife accident can be complex. Depending on the circumstances, multiple parties may be held responsible:

  • Truck driver: If the accident occurred due to speeding, distracted driving, or fatigue, the driver may be directly at fault.
  • Trucking company: Employers can be held liable for negligent hiring, lack of training, or failure to maintain the truck.
  • Cargo loaders: Improperly loaded cargo that contributes to a loss of control can place liability on third-party contractors.
  • Truck manufacturers: If a mechanical defect or faulty part caused the accident, the manufacturer may be liable under product liability laws.

Florida follows a modified comparative negligence rule. This means even if the victim is partially at fault but less than 51% at fault, they may still recover damages. However, the compensation will be reduced in proportion to their degree of fault. If they are 51% or more at fault, they won’t be able to recover at all.

Common Injuries in Jackknife Accidents

Given the sheer size and momentum of semi-trucks, the injuries sustained in jackknife accidents are often catastrophic. Common injuries include:

  • Traumatic brain injuries (TBI)
  • Spinal cord injuries and paralysis
  • Broken bones and fractures
  • Internal organ damage
  • Severe lacerations and burns
  • Psychological trauma, including PTSD
    In the most tragic cases, jackknife accidents can result in wrongful death, leaving families devastated emotionally and financially.

If you feel any sort of symptoms after a Jackknife Accident, it is best to seek medical advice as soon as possible.

What Compensation Can Victims Receive?

Victims of jackknife accidents in Florida may be entitled to several forms of compensation, including economic damages such as:

  • Medical expenses: Past and future treatment, surgeries, medications, and rehabilitation.
  • Lost wages: Including future loss of earning capacity.
  • Pain and suffering: Physical pain and emotional distress.
  • Property damage: Vehicle repairs or replacement.

Victims may also be able to recover for non-economic damages, such as:

  • Loss of consortium: Compensation for the loss of companionship or support.
  • Loss of enjoyment: Compensation for the inability to enjoy activities or hobbies that the person once did due to the injury.
  • Emotional distress: Compensation for the psychological impact caused by the injury, including anxiety, depression, and mental anguish.
  • Pain and suffering: Compensation for the physical and mental distress caused by the injury, including both immediate and long-term effects.

In rare cases involving gross negligence or intentional misconduct, punitive damages might also be available. A seasoned personal injury lawyer will ensure all potential damages are thoroughly evaluated and included in your claim.

What To Do After a Jackknife Truck Accident

If you’re involved in a jackknife accident, follow these steps to protect your legal rights:

  • Call 911: Report the accident and request medical assistance for anyone injured.
  • Document the scene: Take photos and videos of the vehicles, road conditions, and any visible injuries. Note the names and badge numbers of law enforcement officers on the scene.
  • Seek medical attention: Even if injuries seem minor, get evaluated by a medical professional. Some injuries may not show symptoms right away.
  • Do not admit fault: Avoid discussing fault or making statements to insurance adjusters without legal counsel.
  • Contact a truck accident attorney: Truck accident cases are highly complex and involve federal and state regulations. 

Working with an experienced Florida personal injury attorney ensures your rights are protected and the responsible parties are held accountable.

Florida’s trucking industry is regulated under both state and federal laws. The Federal Motor Carrier Safety Administration (FMCSA) sets national standards for hours of service, driver qualifications, and vehicle maintenance. At the state level, Florida also outlines safety regulations specific to commercial motor vehicles. 

It includes rules for driver qualifications, vehicle inspections, hazardous materials transport, and more. Violations of these rules can serve as strong evidence of negligence in a personal injury case.
