Few crashes are as terrifying as a jackknife accident involving a commercial truck. When a tractor-trailer folds at the hitch point and the trailer swings outward, it can block multiple lanes of traffic in seconds. On busy Dallas highways like I-35E, I-30, and I-635, a jackknifed truck can trigger a chain-reaction collision affecting dozens of vehicles.
Because jackknife crashes often involve sudden loss of control, determining liability requires detailed investigation. When negligence plays a role, an experienced Dallas Truck Accident Attorney can help identify responsible parties and pursue full compensation.What Is a Jackknife Accident?
A jackknife accident occurs when the trailer of a tractor-trailer swings outward from the cab, forming an angle that resembles a folding pocketknife. This typically happens when the trailer loses traction and moves faster than the cab.
Once a truck jackknifes, the driver may lose complete control of the vehicle. In heavy traffic, surrounding drivers often have little or no time to react.Common Causes of Jackknife Accidents
Jackknife crashes are rarely random. They often result from preventable factors, including:Sudden or Hard Braking
Abrupt braking—especially at high speeds—can cause the trailer to slide.Slippery Road Conditions
Rain, oil, or debris on Dallas roadways can reduce traction.Speeding
Excessive speed increases stopping distance and reduces stability.Improperly Loaded Cargo
Uneven weight distribution can destabilize the trailer.Worn or Defective Brakes
Brake imbalance between tractor and trailer can cause the trailer to swing.Driver Inexperience
Improper handling during emergency maneuvers can trigger loss of control.
Each of these issues may contribute to liability.The Role of Trucking Companies
Liability may extend beyond the driver. A trucking company may share responsibility if it:
- Failed to maintain braking systems
- Encouraged unrealistic delivery schedules
- Did not properly train drivers
- Ignored prior safety violations
- Allowed overloaded or improperly secured cargo
Company policies and maintenance records often play a central role in jackknife accident claims.
A knowledgeable Dallas Truck Accident Attorney can investigate whether corporate negligence contributed to the crash.Injuries Common in Jackknife Accidents
Because jackknife crashes often block multiple lanes, they frequently lead to multi-vehicle collisions. Injuries may include:
- Traumatic brain injuries
- Spinal cord damage
- Broken bones
- Internal organ injuries
- Severe soft tissue trauma
- Permanent disability
In high-speed highway accidents, the severity of harm can be life-changing.Evidence Used to Prove Fault
Proving liability in a jackknife accident often requires extensive evidence, such as:
- Electronic control module (ECM) data
- Electronic logging device (ELD) records
- Brake maintenance logs
- Cargo weight documentation
- Accident reconstruction analysis
- Surveillance or dashcam footage
Skid mark patterns and trailer angle analysis can also reveal how and why the truck lost control.
Because electronic data may be overwritten, early legal action is critical.Texas Comparative Negligence Rules
Texas follows a modified comparative negligence system. If an injured party is partially responsible, compensation may be reduced proportionally. If more than 50% at fault, recovery may be barred.
Insurance companies may attempt to argue that weather or another driver caused the trailer to swing. Strong technical evidence is often necessary to counter these claims.Why Immediate Legal Action Matters
Trucking companies frequently deploy rapid response teams after serious crashes. Their goals may include:
- Securing electronic data
- Interviewing drivers
- Limiting corporate liability
- Managing public perception
An experienced Dallas Truck Accident Attorney can send preservation notices, coordinate accident reconstruction, and protect your rights from the outset.What to Do After a Jackknife Accident
If you are involved in a jackknife crash:
- Seek immediate medical attention.
- Contact law enforcement.
- Document vehicle positions and road conditions if possible.
- Avoid discussing fault at the scene.
- Preserve all medical and employment records.
These steps can strengthen your case.Final Thoughts
Jackknife truck accidents are among the most dangerous collisions on Dallas highways. Because they often involve loss of control and multiple vehicles, determining fault requires careful analysis of braking systems, cargo loading, driver behavior, and company policies.
When negligence contributes to a jackknife crash, injured victims deserve strong legal advocacy. With experienced representation, it is possible to pursue full compensation and hold both drivers and trucking companies accountable for preventable harm.
