How Do Jackknife Accidents Happen?
A jackknife accident occurs when a semi-truck's trailer swings outward and forms an angle with the cab, resembling the folded blade of a pocketknife. When this happens on a busy highway or intersection, the trailer can sweep across multiple lanes in seconds, leaving other drivers with no time to react. The results are often catastrophic.
These accidents most commonly occur when a truck driver brakes too hard or too suddenly. When the cab slows faster than the trailer behind it, the trailer can lose traction and begin to swing. Slick roads from rain or ice make this kind of loss of control far more likely. Improper braking technique, fatigued driving, distractions, and excessive speed for road conditions can all contribute to a jackknife wreck.
Equipment failures such as brake defects or trailer coupling problems can also play a role. In some cases, a truck that is improperly loaded or carrying an unbalanced cargo load is more susceptible to this type of instability.
Who Can Be Made to Pay for Your Damages After a Truck Wreck?
Commercial truck accidents involve a web of potential liability that goes well beyond the driver alone. The trucking company that employed the driver may be responsible if it failed to properly train the driver, pushed unrealistic delivery schedules that led to fatigued driving, or ignored warning signs about a driver's safety record. A company that leased the truck or trailer may share responsibility depending on how control over the vehicle was structured.
If a brake defect or mechanical failure contributed to the jackknife, the manufacturer of the defective component or the maintenance provider responsible for keeping the truck in safe operating condition may also be liable.
Cargo loading companies can be held accountable when an improperly secured or distributed load made the truck unstable. Identifying every party that contributed to the crash requires a thorough investigation, and it matters because each responsible party may carry separate insurance coverage that can be pursued on your behalf.
Preserving Evidence in a Jackknife Accident Claim
Truck accident evidence can disappear if steps are not taken to secure it. Trucking companies often carry out their own investigations after a serious crash. They have an interest in controlling the narrative and limiting their exposure, which is why it is important to have legal representation working on your behalf as early as possible.
Critical evidence in a jackknife claim can include the truck's black box data, which records braking, speed, and other vehicle information leading up to the collision. Inspection records and driver logs can all shed light on what led to the accident.
Surveillance footage, witness statements, and accident reconstruction analysis can further support your claim. Some of this evidence is subject to routine destruction or overwriting on a short cycle. An attorney can send preservation letters and take legal steps to prevent that from happening.
