Jackknife truck accidents are among the most dangerous crashes on Oklahoma highways. When a tractor-trailer folds at the hinge between the cab and trailer, it forms an L- or V-shape, often sweeping across multiple lanes of traffic. These accidents frequently cause multi-vehicle collisions, catastrophic injuries, and fatalities.
If you or a loved one has been injured in a jackknife accident in Oklahoma City, you may be entitled to compensation. At Pasquali Law Firm, our experienced truck accident lawyers understand the complexity of these cases and fight aggressively to hold negligent trucking companies and drivers accountable.

What Is a Jackknife Truck Accident?
A jackknife occurs when the trailer of a semi-truck swings out at an angle, creating a folding motion with the cab. This usually happens when a driver loses control, causing the trailer to skid sideways. The force of a jackknife often blocks multiple lanes of traffic, leading to devastating pileups.
These accidents are especially common on busy highways like I-35, I-40, and I-44 that pass through Oklahoma City, where large trucks travel at high speeds.
Causes of Jackknife Truck Accidents
Jackknife accidents often result from negligence, unsafe driving practices, or equipment failure. Common causes include:
- Speeding – Traveling too fast, especially on curves or in bad weather.
- Sudden braking – Hard braking can cause a trailer to swing out of control.
- Driver fatigue – Exhausted truck drivers have slower reaction times.
- Distracted driving – Using phones, GPS, or other devices behind the wheel.
- Overloaded or improperly loaded cargo – Shifts in weight can destabilize the trailer.
- Poor weather conditions – Rain, snow, or ice increase the risk of skidding.
- Mechanical failures – Defective brakes or tire blowouts can trigger jackknifes.
In many cases, both the truck driver and the trucking company may share responsibility.
Injuries from Jackknife Crashes
Because of the sheer size and weight of 18-wheelers, jackknife accidents often cause catastrophic injuries, including:
- Traumatic brain injuries (TBI) – from head impacts or flying debris.
- Spinal cord injuries – resulting in paralysis or permanent disability.
- Broken bones and fractures – common in multi-vehicle collisions.
- Internal injuries – organ damage or internal bleeding.
- Burns and lacerations – from fires or shattered glass.
- Fatal injuries – wrongful death claims are tragically common in these cases.
Victims may require emergency surgery, long-term rehabilitation, and lifelong medical care.
Who Is Liable in a Jackknife Truck Accident?
Determining fault in a jackknife accident is complex. Liability may extend beyond the truck driver to include multiple parties:
- Truck driver – for negligent driving, speeding, or fatigue.
- Trucking company – for poor hiring practices, inadequate training, or pressuring drivers to meet unrealistic deadlines.
- Cargo loaders – if the load was unbalanced or unsecured.
- Maintenance providers – for failing to properly service brakes, tires, or other equipment.
- Manufacturers – if defective truck parts contributed to the crash.
An Oklahoma City jackknife truck accident lawyer will investigate thoroughly to identify all responsible parties and pursue maximum compensation.
Compensation Available for Victims
Victims of jackknife truck accidents may be eligible for a variety of damages, including:
- Medical expenses – past, present, and future treatment.
- Lost wages – income lost during recovery.
- Reduced earning capacity – if injuries prevent returning to work.
- Property damage – repair or replacement of your vehicle.
- Pain and suffering – physical and emotional distress.
- Loss of enjoyment of life – when injuries limit normal activities.
- Wrongful death damages – funeral expenses and loss of support for families who lost loved ones.
Because these accidents often involve trucking companies with powerful insurers, it’s critical to have an attorney who won’t settle for less than you deserve.
