How Common Are Jackknife Accidents?
Unfortunately, jackknife accidents are more common than many people realize. Federal data shows 5,169 jackknife accidents in 2023, the most recent reporting year.
Because these crashes involve large trucks, they carry a much higher risk of property damage, fatalities, and multi-vehicle collisions. In Illinois, the Department of Transportation recorded 336 crashes involving tractor-trailer combination vehicles in 2023 alone.
These numbers highlight just how dangerous jackknife truck accidents can be for drivers in Lake County and throughout Illinois.
What Happens When a Truck Jackknifes?
A jackknife happens when a trailer swings around next to the semi truck pulling it, creating a V shape.
Many drivers who have never operated a commercial vehicle might not appreciate the difficulty and challenges of safely pulling a trailer. Many factors may cause these accidents.
For example:
- Speeding
- Improper braking
- Adverse weather conditions
- Improperly loaded cargo
- Equipment failure
Additionally, fatigued or inexperienced drivers may not react appropriately to these conditions and fail to prevent a jackknife accident from happening.
Because so many factors can contribute, jackknife accidents are often complex events that require careful investigation to determine who is at fault.
Who Is Liable for a Jackknife Accident in Lake County?
Ultimately, both the truck driver and their employer are responsible for ensuring the safe operation of a commercial vehicle. Jackknife accidents often occur when a driver speeds, fails to account for icy conditions, or brakes suddenly, and in these cases, the driver and trucking company can be held liable.
In some cases, other parties may also share responsibility. For example, a truck or parts manufacturer could face product liability if a defective component contributed to the accident.
At the same time, local government agencies may be at fault for designing unsafe roads, failing to clear hazards, or neglecting to warn drivers of dangerous conditions.
Because liability can involve multiple parties, it is crucial to work with an experienced Lake County jackknife accident lawyer who can identify every source of compensation.
