How to Determine Fault in Jackknife Truck Accidents

A jackknife accident involves a situation where a truck’s trailer swings out from behind the cab, forming an angle that resembles the folding of a pocketknife. This type of accident is particularly dangerous because the trailer can sweep across multiple lanes of traffic, causing severe collisions with other vehicles.


How Jackknife Accidents Occur


Several factors can contribute to a jackknife accident. Some of the most common causes include:


  • Braking Issues: If a truck driver brakes too suddenly, particularly in wet or icy conditions, the wheels of the trailer may lock up. This can cause the trailer to swing out of control.

  • Speeding: Traveling at high speeds can reduce a driver’s ability to control the truck, making it more likely for the trailer to jackknife during sudden maneuvers.

  • Improper Loading: Unevenly distributed or improperly secured cargo can shift during transit, destabilizing the trailer and increasing the risk of a jackknife.

  • Mechanical Failures: Faulty brakes, tires or other mechanical issues can lead to a loss of control and subsequent jackknife.

  • Driver Error: Inexperience, distraction or fatigue can lead to poor decision-making and response times, contributing to jackknifing.


The Legal Process for Determining Fault


Determining fault in a jackknife accident involves a thorough investigation of the incident.


Here are the key steps in the legal process:


  1. Accident Investigation: Immediately following a jackknife accident, law enforcement and accident investigators will examine the scene. They will look at skid marks, vehicle positions and road conditions to see how the accident occurred.

  2. Gathering Evidence: Critical evidence includes witness statements, traffic camera footage and data from the truck’s electronic logging device (ELD). The ELD can provide information on the truck’s speed, braking patterns and hours of service.

  3. Driver’s Record: Investigators will review the truck driver’s records, including driving history, training and compliance with hours-of-service regulations. Any history of violations or infractions can influence fault determination.

  4. Mechanical Inspection: A thorough inspection of the truck and trailer will be conducted to identify any mechanical failures or maintenance issues that could have contributed to the accident.

  5. Cargo Analysis: If improper loading is suspected, investigators will review cargo logs and procedures to determine if the load was a factor in the jackknife.

Assigning Fault


Fault in a jackknife accident can be attributed to various parties depending on the findings of the investigation. The truck driver can be held liable if their actions, such as speeding, distracted driving or violation of hours-of-service regulations, directly caused the accident. The trucking company may be liable if they failed to maintain the vehicle properly, did not ensure the driver was adequately trained or pressured the driver to violate safety regulations.


If improper loading or securing of the cargo is found to be a factor, the company responsible for loading the truck can be held accountable. In cases where mechanical failure is due to a defect in the truck or its parts, the manufacturer of the faulty component could be held liable. Additionally, other parties such as maintenance providers or contractors who serviced the truck may also be found liable if their negligence contributed to the accident.


Proving Negligence


To establish fault, the injured party must prove that negligence occurred.


This involves demonstrating that:


  • Duty of Care: The truck driver and trucking company owed a duty of care to other road users to operate the vehicle safely.

  • Breach of Duty: The driver or company breached this duty through actions such as speeding, improper maintenance or failing to follow safety regulations.

  • Causation: The breach of duty directly caused the jackknife accident.

  • Damages: The accident resulted in actual damages, such as injuries, property damage or financial loss.


Legal Representation for Jackknife Accidents


Given the complexity of jackknife accidents, it is advisable for victims to seek legal representation. An experienced attorney can navigate the intricacies of the investigation, gather critical evidence and build a compelling case for compensation.
