How Jackknife Accidents Happen and Who Is Usually to Blame
A jackknife happens when the tractor slows or stops while the trailer keeps moving and swings out until the rig forms a sharp angle, like a folding knife. Common causes include hard braking at speed, taking curves or ramps too fast, empty or unevenly loaded trailers, worn brakes, and wet pavement.
Fault often rests with more than one party: the driver, a carrier that set an unrealistic schedule, the company that loaded the cargo, or a shop that skipped brake repairs. Our Nashville truck accident attorneys examine every link in that chain.
Federal and Tennessee Rules on Speed, Braking, and Cargo Weight
Commercial trucks on Tennessee highways must follow the Federal Motor Carrier Safety Regulations. Drivers must reduce speed and use extreme caution in hazardous conditions such as rain, fog, snow, or ice. Carriers must keep brakes in working order and secure cargo so it cannot shift. Federal hours-of-service rules generally limit truckers to 11 hours of driving after 10 consecutive hours off duty, because fatigue slows the split-second reactions that prevent a jackknife.
Tennessee law also sets maximum weight limits for trucks and their axles and requires special permits for heavier loads. An overloaded trailer is harder to stop and more likely to swing out, and proof that a carrier broke these rules can strengthen your claim.
Jackknife Risks Where I-24, I-40, and I-65 Converge
Around downtown, Nashville’s three interstates share pavement. I-24 and I-40 run together for about two miles southeast of downtown (I-40 Exits 211–213), I-40 and I-65 overlap for about two miles along the west side of downtown near Music Row and The Gulch (I-40 Exits 208–210), and I-24 and I-65 combine for about two miles north of downtown, including the Trinity Lane exit (I-65 Exit 87). Short merges and sudden slowdowns leave heavy trucks little room to stop.
Beyond downtown, risk continues on I-24 through Antioch and La Vergne, on I-40 past Donelson and Hermitage, and at the I-40 interchange with Donelson Pike (SR 255, Exit 216) beside Nashville International Airport, where TDOT opened a new diverging diamond interchange in June 2025.
Common Injuries From Jackknife Collisions
Because a jackknifed trailer can sweep across several lanes, injuries are often serious:
- Traumatic brain injuries and concussions
- Spinal cord injuries, including paralysis
- Fractures and crush injuries
- Internal bleeding and organ damage
- Burns from fuel or cargo fires
- Scarring, disfigurement, and PTSD
Symptoms of head trauma can surface days later. Learn how we build Nashville brain injury claims with input from medical experts.
What a Strong Claim Can Cover
We work with doctors, life care planners, and economists to document losses that can stretch years ahead:
- Medical care: Surgery, rehabilitation, therapy, and medication, now and in the future.
- Lost earning capacity: Missed wages, plus the raises, promotions, and retirement savings an injury can take away.
- Changes at home: Home modifications, mobility equipment, in-home help, and vocational retraining.
- Pain and suffering: Physical pain, emotional distress, and lost enjoyment of life.
Tennessee does not cap out-of-pocket losses such as medical bills and documented lost wages. Pain and suffering and other noneconomic damages are generally capped at $750,000, rising to $1 million for certain catastrophic injuries, such as a spinal cord injury that causes paralysis. The caps do not apply in a few situations, such as when the at-fault driver was impaired by alcohol or drugs. We explain how these rules apply to your case.
Punitive damages are rare. A Tennessee court can award them only when the injured person proves by clear and convincing evidence that the defendant acted intentionally, fraudulently, maliciously, or recklessly. They are generally capped at twice the compensatory damages or $500,000, whichever is greater. We will tell you honestly whether your case may qualify.
Why Nashville Families Trust Us After a Truck Crash
We know Tennessee law. Tennessee generally gives injured people only one year from the crash to file a lawsuit, one of the shortest deadlines in the country. The state also follows modified comparative fault: you can still recover if you were less than 50% at fault, with your award reduced by your share.
We know how insurers operate. Many of our Nashville attorneys previously worked as defense attorneys for the insurance industry. That inside view helps us anticipate the tactics adjusters use to shrink truck claims.
You pay nothing unless we win. We work on a contingency fee basis, so there are no upfront costs and no attorney fees unless we recover money for you. Contact us at 404-640-5761.
How to Get Started
- Free consultation: Tell us what happened in a confidential, no-pressure conversation.
- Investigation: We obtain the police or Tennessee Highway Patrol crash report, demand trucking records, and bring in specialists.
- Advocacy: We handle every call and letter from insurers so you can focus on recovery.
Your Jackknife Accident Questions, Answered
How long do I have to file a jackknife truck accident claim in Tennessee?
In most cases, one year from the date of the crash. The deadline can extend to two years if criminal charges are brought against the person who caused the crash, though a city traffic ticket usually does not qualify. Property damage claims generally have a three-year deadline. Calling us early keeps every option open.
What if the police report says I was partly to blame?
A crash report matters, but it is not the final word on fault. Black box data and witnesses can tell a different story. Even if some blame is assigned to you, Tennessee lets you recover as long as your share of fault is less than 50%, with your compensation reduced by that share.
How much insurance does a trucking company carry?
Federal rules require for-hire interstate carriers hauling non-hazardous freight to carry at least $750,000 in liability coverage, and more for certain hazardous materials. Many carry higher limits. We also look for coverage from cargo owners, maintenance companies, and parts manufacturers so no source of recovery is missed.
Can my family file a claim if a jackknife crash was fatal?
Yes. A surviving spouse can bring a wrongful death claim; if there is no spouse, the children or next of kin can. The estate’s personal representative can also file. The claim can seek medical and funeral costs, lost income, and the loss of companionship. Learn more about Nashville wrongful death claims and how we support grieving families.
Should I talk to the trucking company’s insurance adjuster?
Be careful. Adjusters work to limit what their company pays, and early statements can be used against you. Share only basic facts, such as when and where the crash happened and who was involved, and do not discuss fault or your injuries.
