When an 18-wheeler or semi-truck folds in on itself, forming an L or V shape, it’s called a jackknife accident. This type of crash is extremely dangerous because the driver loses control, and the truck can swing across multiple lanes, hitting anything in its path.
The aftermath is often catastrophic. Victims often face serious injuries, crushed vehicles, and trauma that lingers long after the scene is cleared. It is when an experienced jackknife accident attorney plays a pivotal role. Reaching out to them right after such a crash can help protect your rights, handle negotiations with insurers, and build a strong case for compensation.
Truck accidents are not like typical car collisions. They involve larger vehicles, complex insurance policies, and stricter federal regulations. Injury and car accident lawyers investigate what went wrong and ensure victims receive the justice they deserve.
What causes these terrifying jackknife truck accidents?
Let’s take a closer look here!
- Sudden Braking or Skidding: One of the most common triggers for a jackknife accident is sudden braking. When a truck driver slams on the brakes, the trailer can swing out due to momentum, especially on slick roads.
Unlike smaller vehicles, trucks need a lot more distance to come to a complete stop safely. If that space isn’t available, the risk of a jackknife increases significantly. - Poor Weather Conditions: Rain, snow, or icy roads can quickly turn a manageable drive into a nightmare. Wet or frozen surfaces reduce tire traction, making it harder for the driver to maintain control. Even seasoned truckers can struggle to prevent skidding on slippery highways.
When weather plays a role, truck accident attorneys often investigate whether the driver or trucking company failed to take proper precautions before hitting the road. - Improper Cargo Loading: How cargo is loaded inside the trailer can directly affect a truck’s balance and stability. If the load is uneven or unsecured, it can shift during turns or braking, throwing the truck off balance and causing the trailer to swing outward.
Trucking companies are legally required to ensure cargo is properly distributed and secured. When they cut corners, injury and car accident lawyers can hold them accountable for negligence. - Equipment Failure: Faulty brakes, worn-out tires, or defective coupling systems can all contribute to a jackknife incident. Trucking companies are required to maintain their fleets and perform regular inspections.
Unfortunately, maintenance often gets overlooked in the rush to meet delivery deadlines. When a mechanical failure causes an accident, both the trucking company and equipment manufacturers could be held responsible. - Driver Fatigue: Long hours, tight delivery schedules, and pressure to meet deadlines can push drivers beyond their physical limits. As a consequence, a tired driver might brake too late, lose focus, or misjudge a turn—leading to a jackknife accident.
Sadly, injury lawyers often uncover that companies encourage drivers to exceed federal hours-of-service rules, putting everyone on the road at risk. - Speeding and Aggressive Driving: Speed and size are a deadly mix. When an 18-wheeler barrels down the highway too fast, the driver has little room to maneuver safely. Aggressive actions, like tailgating, swerving, or sudden lane changes, can easily send the trailer swinging out of alignment.
Experienced truck accident attorneys often rely on data from onboard systems, GPS, and traffic footage to show that reckless or speeding behavior led to the crash.
