When it comes to road safety, few incidents are as terrifying and potentially catastrophic as a jackknife truck accident. These crashes are named for the way a folding knife bends at the hinge.
The result is often a loss of control that can span multiple lanes, endanger countless drivers and cause significant property damage or injury. While many factors can contribute to a jackknife incident, specific traffic situations increase the risk exponentially.
Sudden braking in high-speed traffic
Trucks require a much greater stopping distance than smaller vehicles due to their size and weight. A truck driver may brake suddenly, perhaps:
- To avoid a slow-moving vehicle
- Due to unexpected traffic jam
- Due to road debris
The wheels can lock up in such scenarios, especially on slippery roads. When this happens, the trailer’s momentum may cause it to swing outward, leading to a jackknife.
Improper downhill navigation
Gravity adds momentum when a truck descends a long or steep hill, making it harder to maintain control. If the driver applies the brakes too aggressively or fails to downshift to a lower gear, it can lead to overheating brakes or uneven braking between the tractor and trailer. Either situation significantly increases the chance of the trailer swinging outward—especially if traction is compromised due to weather conditions or heavy cargo loads.
Sharp turns on wet or curvy roads
Turning sharply, especially at higher speeds or on slick roads, is a recipe for disaster for large trucks. In these conditions, the trailer may slide sideways due to inertia, even if the cab is attempting to safely navigate the turn. Curvy roads, freeway ramps and urban intersections with tight turning radii are common culprits.
Jackknife accidents are among the most preventable yet dangerous hazards on the road. Passenger vehicle drivers who encounter these collisions should enlist dedicated legal guidance to get to the root of the accident and to clarify their options to seek compensation accordingly.
