When the Cab Turns and the Trailer Doesn't Follow
A jackknife happens when a truck and its trailer fold together at the hitch, like a pocketknife partly open. The cab turns one way, the driver loses control of the trailer, and the trailer keeps pushing forward, often sweeping across lanes of traffic. These crashes are most common among semi-trucks and other large commercial vehicles pulling hitched cargo, and they can leave the people around them with severe, sometimes permanent injuries.
A truck doesn’t fold on its own. The causes usually trace back to a decision or a failure:
Speeding
Making a turn too sharply
Overweight trucks
Vehicle defects
Slick roads from bad weather
A driver who was distracted, intoxicated, or fatigued
Each cause points to someone who can be held responsible. If you were hurt in a jackknife crash in Sunnyvale, talk to us before the truck is repaired and the evidence is gone. The consultation is free, and you pay nothing unless we win.
After a Jackknife Crash: Six Things to Do
Get out of the path of traffic if it's safe, and call 911.
A trailer lying across lanes is a danger to everyone still approaching.
Let paramedics examine you.
The impact of a trailer swing can cause serious injuries that aren’t obvious in the moment.
Photograph how the truck came to rest.
The angle between cab and trailer, the cargo, tire marks, and the weather and road surface all help explain why it folded.
Note what the truck was doing just before.
Taking a curve or turn, braking hard, going fast for the conditions: tell the officer and write it down.
Identify the truck and its owner.
The company name and the numbers on the cab and trailer lead us to the business that owns the truck and employs the driver.
Send every insurance call to us.
Adjusters for the trucking company, and sometimes for other drivers, may call quickly. Don’t give statements or sign anything.
What Your Jackknife Claim Can Include
Medical care expenses
Emergency treatment, hospital care, surgery, rehabilitation, and the care you’ll need going forward.
Lost earnings due to disability
The income you lose while you recover, and the earnings you lose if your injuries keep you from returning to your job.
Pain and suffering
Compensation for the physical pain and emotional distress of a violent crash and a long recovery.
Other losses
Property damage and the other costs the crash has caused you. What a claim is worth depends on how severe your injuries are and on factors like your occupation.

Why the Cause Decides Who Pays
Finding out why a truck jackknifed is the key to finding out who is liable. We reconstruct the crash from the physical evidence, the police report, and witness accounts, then look at the parts of the story that only the trucking company’s records reveal:
- Speed and handling: whether the driver was going too fast for the road or made a turn too sharply
- The load: whether the truck was overweight, and who loaded it
- The equipment: whether a defect or poor maintenance played a role
- The driver’s condition: signs of distraction, intoxication, or fatigue
Our associates have experience working at insurance companies, so we know how a trucking insurer evaluates a claim like yours. We aim to secure compensation through a fair settlement, on a timeline that fits your needs, but if a settlement isn’t possible, we’re ready to file a lawsuit and take the case to court.
Liability for Jackknife Crashes in California
The owner and the driver can both be responsible
California law can hold a vehicle’s owner liable for injuries caused by the negligent operation of the vehicle, including by a driver using it with the owner’s permission. With commercial trucks, liability may fall on the business that owns the truck as well as the employed driver.
Losing control is not a defense
A truck that jackknifes because of speed, a sharp turn, an overweight load, or an impaired driver points to negligence, not bad luck.
Partial fault only reduces your recovery
Under California’s pure comparative negligence rule, any share of fault assigned to you lowers your compensation by that share; it never eliminates it.
Two years to file a lawsuit
California generally allows two years from the date of the collision to file a personal injury lawsuit. Missing the deadline can end your claim.

Sunnyvale Jackknife Truck Accident FAQs
What exactly is a jackknife accident?
The truck and its trailer fold together at the hitch. The cab turns in one direction while the trailer keeps pushing forward, often ending up at an angle across the road.
What makes a truck jackknife?
Common causes include speeding, turning too sharply, an overweight truck, vehicle defects, and slick roads. Driver distraction, intoxication, or fatigue can also lead to a jackknife.
Who can be held liable?
Usually the truck driver and the business that owns the truck and employs them. Depending on the cause, others, such as whoever loaded an overweight truck, may share responsibility.
Does bad weather let the trucker off the hook?
No. Slick roads make a jackknife more likely, which is exactly why drivers are expected to slow down and handle the truck carefully when conditions are poor.
How much is my jackknife case worth?
It depends on the severity of your injuries and other factors, such as your occupation and how the injuries affect your ability to work. We’ll give you a realistic assessment once we know the facts.
Will I have to go to court?
Not necessarily. Many cases resolve through settlement. If a fair settlement isn’t possible, you keep the right to file a lawsuit, which is why it’s important to act before the deadline.
How long do I have to file?
Generally two years from the date of the collision to file a lawsuit. The sooner you call, the sooner we can start settlement discussions and preserve evidence.
What does hiring you cost?
Nothing upfront. We work on contingency; you pay a fee only if we recover for you.
