Jackknife Truck Accident Lawyers
A jackknife accident occurs when a tractor-trailer’s cab and trailer fold toward each other at the pivot point (the fifth-wheel coupling), forming a shape resembling a folding jackknife. During a jackknife, the trailer can swing out at a 90-degree angle to the cab, sweeping across multiple lanes of traffic and striking any vehicles in its path. These crashes are especially dangerous on highways and interstates where surrounding vehicles are traveling at high speeds and have little time or space to react.
At Roden Law, our jackknife accident lawyers understand the mechanical causes, driver errors, and maintenance failures that lead to these devastating multi-vehicle crashes. We hold trucking companies accountable for putting poorly maintained and unsafely operated trucks on Georgia and South Carolina roads.
What Causes Jackknife Accidents?
Jackknife events occur when the tractor’s drive wheels lose traction or the trailer’s momentum exceeds the cab’s ability to control it. Common causes include:
- Sudden or hard braking: The most common cause — when a driver brakes abruptly, the trailer’s momentum can push it forward and to the side, causing it to swing around
- Wet or icy road conditions: Reduced traction makes jackknifing much more likely, especially when a driver brakes or accelerates on slippery surfaces
- Excessive speed: Higher speeds increase the risk of loss of control, particularly on curves, ramps, and in construction zones
- Empty or lightly loaded trailers: A lighter trailer has less traction on the road and is more susceptible to swinging during braking
- Brake imbalance or malfunction: When brakes on one side or one axle engage differently than the other, the resulting uneven forces can trigger a jackknife
- Improper coupling: A loose or defective fifth-wheel connection allows the trailer to pivot more freely than designed
- Driver inexperience: Inexperienced truck drivers may not know how to recognize and correct an incipient jackknife, or may use improper braking techniques
Why Jackknife Crashes Are So Dangerous
Jackknife accidents create several simultaneous hazards:
- Multi-lane blockage: A jackknifed trailer can span the entire width of a highway, blocking all lanes of traffic
- Chain-reaction collisions: Vehicles behind the jackknifing truck have minimal time to react, often resulting in multi-vehicle pileups
- Crushing injuries: Vehicles adjacent to the trailer can be struck by the swinging trailer broadside
- Cargo spills: The violent motion of a jackknife can breach cargo containers, spilling freight or hazardous materials across the roadway
- Secondary crashes: Even after the initial jackknife, the blocked roadway creates ongoing hazards for approaching traffic
Proving Liability in Jackknife Cases
Our attorneys investigate every potential cause and liable party in jackknife accidents:
- The truck driver: For speeding, improper braking technique, following too closely, or driving too fast for road conditions
- The trucking company: For inadequate driver training, failure to maintain anti-lock braking systems, or dispatching trucks in dangerous weather conditions
- Maintenance providers: For failing to properly maintain brakes, tires, coupling mechanisms, and stability control systems
- Other negligent drivers: Whose actions may have forced the truck driver to brake suddenly
We work with accident reconstruction experts to analyze event data recorder information, road conditions, vehicle maintenance records, and driver training files. Under Georgia’s modified comparative fault rule (O.C.G.A. § 51-12-33) and South Carolina’s similar standard, we can recover damages even when multiple parties share fault, as long as the victim is less than 50% (GA) or 51% (SC) at fault.
