In Texas, a jackknifed or rolled tractor-trailer almost always traces back to speed, brakes, load, or driver error, all of which are documented in records the carrier controls. Owsley Law Firm obtains those records and charges no fee unless it wins. Call the same week so the truck and its data are preserved.
What causes a truck to jackknife?
A jackknife happens when the trailer swings out and around the cab, folding the rig like a pocketknife. It usually starts with the drive wheels or trailer wheels locking under hard braking.
- Speed too fast for traffic, curves, or wet pavement
- Sudden hard braking, often after following too closely
- Brakes out of adjustment, so the trailer and tractor brake unevenly
- An empty or lightly loaded trailer, which is more likely to swing
- Worn tires or a tire failure
What causes a truck rollover?
Tractor-trailers have a high center of gravity. Rollovers follow sharp steering corrections, taking a ramp or curve too fast, drifting off the pavement edge and over-correcting, and cargo that shifts during a turn. Tankers carrying liquid are especially prone to rollovers because the load surges. Cargo securement rules in 49 CFR Part 393 and speed limits under the Texas Transportation Code both apply.
Freeway interchanges with tight ramps, such as those where I-10, I-45, and the 610 Loop meet, are common rollover locations because a driver who misjudges the curve has little room to recover. Construction zones that shift lanes add to the risk.
Who is at fault in a jackknife or rollover crash?
Several parties can share responsibility, and Texas proportionate responsibility under Chapter 33 allocates fault among them.
Interstate carriers hauling general freight must carry at least $750,000 in liability coverage under 49 CFR 387.9, and carriers of oil and hazardous materials must carry more. Many carriers carry excess coverage above the minimum. Identifying every policy, including the trailer owner’s and any broker’s, matters when injuries are severe.
- The driver, for speed, following distance, or a dangerous maneuver
- The carrier, for training, scheduling, and maintenance
- A maintenance contractor that serviced the brakes or tires
- The shipper or loader that packed or overloaded the trailer
- The manufacturer of a defective brake, tire, or stability component
Why is the truck itself the most important evidence?
Brake adjustment, tire condition, the load, and the engine control module data that records speed and braking must be examined before the carrier repairs, salvages, or sells the truck. Maintenance records under 49 CFR Part 396 and the driver’s pre-trip inspection report show whether a known defect was ignored. The firm demands preservation immediately and, where necessary, obtains a court order for an inspection.
An independent inspection by a qualified expert, with the carrier’s expert present, documents the condition of the brakes, tires, and coupling before anything changes. Downloading the engine module requires the right equipment and protocol so the data is admissible.
What happens in a multi-vehicle pileup behind a jackknifed truck?
A jackknifed trailer can block every lane of I-10, I-45, or I-610 in seconds, and following vehicles strike the trailer and each other. These cases involve several drivers and insurers. The truck is usually the primary cause and its insurer the primary source of recovery, but each driver’s share of fault has to be sorted out with video, event data, and reconstruction.
Fog, heavy rain, and smoke from fires along highways can turn a single jackknife into a chain of crashes. Weather does not excuse a truck driver who was going too fast for conditions; the law requires speed that is reasonable for the conditions actually present.
What should I do after a jackknife or rollover crash?
Get medical care and make sure police document the crash. Photograph the truck, the trailer, the load, and the scene, including skid marks and debris, and write down the company name and USDOT number shown on the truck. Get witness names, since other drivers often saw the truck’s speed and movement before it lost control. Do not talk to the trucking company’s investigator or insurer before speaking with a lawyer. A preservation letter covering the truck, its brakes, its engine data, and the driver’s logs should go out within days.
What injuries do jackknife and rollover crashes cause?
The weight of a loaded tractor-trailer means these crashes are often catastrophic for people in smaller vehicles: traumatic brain injuries, spinal injuries, crush injuries, multiple fractures, and burns when fuel or cargo ignites. Damages can include lifetime medical care, lost earning capacity, pain, mental anguish, physical impairment, and disfigurement, and exemplary damages may be available under Chapter 41 when a carrier ignored known safety problems.
How long do I have to file?
The general deadline is two years from the crash under Civil Practice and Remedies Code section 16.003. For families who lost someone, the wrongful death deadline generally runs two years from the date of death. The physical evidence disappears much faster.
A lawsuit can also be the fastest way to secure evidence. When a carrier will not agree to preserve the truck voluntarily, filing suit allows the court to order it.
Common questions
What clients ask about jackknife and rollover crashes.
Who is at fault in a jackknife accident?
Usually the driver for speed or braking, the carrier for maintenance or training, or the shipper for loading. The physical evidence and records identify which.
What if my car was one of several hit behind the truck?
Each driver’s share of fault is decided under Texas proportionate responsibility. The truck is usually the primary cause, and its insurer the primary source of recovery.
Can overloaded cargo cause a rollover?
Yes. Federal cargo securement rules and weight limits exist because shifting or excess cargo raises the risk of rollover, especially in curves and on ramps.
Can bad brakes cause a jackknife?
Yes. Brakes out of adjustment can make the tractor and trailer brake unevenly, which is a common jackknife cause. Maintenance records under 49 CFR Part 396 show whether it was preventable.
How quickly should I act after a truck rollover?
Within days. The truck, its data, and the load can be repaired, overwritten, or cleared, and preservation demands should go out right away.
