A jackknife crash happens when a tractor-trailer folds so the trailer swings out at a sharp angle to the cab, often blocking lanes. A truck jackknife lawyer may help when you were seriously hurt, when fault is disputed, or when evidence such as driver logs and vehicle data needs to be preserved quickly.
This guide explains how jackknife crashes are investigated, which federal rules may come into play, and how a Nevada claim works.
Key Takeaways
- A jackknife crash can involve several vehicles because the trailer may sweep across lanes.
- Investigations often look at speed, braking, load, road conditions, and driver hours.
- Federal rules cover hours of service, vehicle maintenance, and cargo securement.
- Some trucking records are kept for limited periods, so early preservation can matter.
- Nevada generally allows 2 years to sue for personal injury under NRS 11.190(4)(e).
What Is a Jackknife Crash?
A tractor-trailer has a cab that pulls a trailer through a pivoting connection. In a jackknife, the trailer and cab end up at a sharp angle, like a folding pocketknife. The trailer may slide across lanes or roll over, and other vehicles may have little room to avoid it.
What Factors Are Investigated in a Jackknife Crash?
| Factor | What may be reviewed |
|---|---|
| Speed | Whether the truck was going too fast for the conditions |
| Braking | How the brakes were applied and whether they were maintained |
| Load | Whether the trailer was empty, overloaded, or unevenly loaded |
| Road and weather | Wet pavement, curves, and downgrades |
| Driver condition | Fatigue, hours of service, and distraction |
| Other vehicles | Whether another driver forced a sudden maneuver |
In FMCSA’s Large Truck Crash Causation Study of 2001 to 2003 crashes, brake problems were recorded for 29% of trucks and traveling too fast for conditions for 23%. That study covered truck crashes generally, not jackknifes specifically, and a factor being present does not mean it caused a crash.
Which Federal Rules Can Apply?
- Hours of service. 49 CFR 395.3 limits property-carrying drivers to 11 hours of driving within a 14-hour window after 10 consecutive hours off duty. See truck driver hours of service rules.
- Phone use. 49 CFR 392.80 and 392.82 prohibit texting and hand-held phone use while driving a commercial motor vehicle, with an emergency exception.
- Maintenance and cargo. Federal rules in 49 CFR Parts 393 and 396 cover vehicle parts, cargo securement, and inspection and maintenance.
Nevada’s regulations under NAC Chapter 706 adopt many of these federal rules by reference. A violation may be evidence of negligence. See negligence per se in Nevada.
When Might You Need a Truck Jackknife Lawyer?
- You or a family member was seriously hurt
- Several vehicles were involved and fault is disputed
- The trucking company or its insurer has contacted you
- Driver logs, vehicle data, or video may be lost
- A family member died, in which case see wrongful death lawsuits

Who Can Be Responsible?
The driver, the motor carrier, a company that loaded the cargo, or a maintenance provider may be reviewed, depending on the facts. If a part failed, see auto defect claims. Under NRS 41.141, where comparative negligence is asserted against multiple defendants, each is generally liable for its own share, and the statute lists exceptions.
What Is the Deadline?
Nevada generally allows 2 years to sue for personal injury or wrongful death under NRS 11.190(4)(e), and 3 years for injury to personal property under NRS 11.190(3)(c). Exceptions can apply. Some federal records are kept for shorter periods, such as the 6-month minimum for duty status records under 49 CFR 395.8(k).
