Jackknifes, rollovers, and tire blowouts look like freak events from the roadside. They almost never are. Each one usually has a cause the federal rules were written to prevent: too much speed, bad braking, a badly loaded trailer, or neglected maintenance. The evidence on the truck usually shows which.
Jackknifes
A jackknife happens when the trailer loses traction and swings out of line with the cab, folding toward it and often sweeping across multiple lanes. The usual culprits are braking too hard or too late, excessive speed for the conditions, following too closely, and worn or poorly balanced brakes. Each of those is either a driving choice or a maintenance failure, and both are things the carrier and driver were responsible for managing.
A jackknife, rollover, or blowout is a physics case before it is anything else, and reconstructing what the forces really show is work I am at my strongest doing. As an ACS-CHAL forensic lawyer-scientist who spent years defending DUI cases, I know how crash evidence is built and attacked, from the speeds and the load to the tire and brake condition the truck was carrying. A carrier moves the day of the wreck to control that story, so I move faster to preserve the black box data, the electronic logs, and the maintenance file before they disappear. I represent injured people, not insurers, and having tried numerous cases as a public defender and cross-examined witnesses constantly, I am ready to put the proof in front of a jury, which is often what makes a trucking insurer pay fair value. I handle your case personally, from the first call through trial. Learn more about my background.
Rollovers
A loaded trailer carries a high center of gravity, so it tips far more easily than a car. Most rollovers come from taking a curve or a highway ramp too fast, from an overcorrection, or from cargo that was loaded too high or left unsecured so it shifted in a turn. When a load was improperly secured, the responsibility can extend to whoever loaded it, a point I take up on who is liable.
Tire blowouts
A blowout at highway speed can send a truck out of control, and it is rarely just bad luck. Tire failures usually trace to underinflation, worn or mismatched tires, overloading, or inspections that were skipped. The federal maintenance rules exist to catch exactly these problems, so a blowout that came from neglected upkeep is the carrier’s failure. The maintenance and inspection records, governed by the federal rules, usually tell the story.
These crashes have causes, not just bad luck
Carriers like to describe a jackknife, a rollover, or a blowout as an unavoidable event, something that just happened, and the truth is almost always the opposite. A jackknife, where the trailer swings out of line with the cab, typically traces to speed, hard or improper braking, or a poorly loaded trailer. A rollover usually involves speed in a curve, a high or shifting center of gravity, or cargo that was not secured the way it should have been. A tire blowout points to the condition and maintenance of the tire, its age, wear, pressure, and inspection history. In each case there is a chain of decisions and conditions behind the crash, and finding it is what separates a real investigation from accepting the carrier’s story. The reconstruction, the maintenance records, the loading documentation, and the physical evidence tell what caused the truck to fail, and that cause is where the liability lives.
Where these failures point, from the shop to the factory
What makes these crashes worth working carefully is that their causes reach responsible parties beyond the driver. A blowout or a brake failure raises the carrier’s duty to inspect and maintain its equipment, a written obligation under the federal regulations, so a failure here is often a maintenance-negligence case built on the company’s own records, or the absence of them. Sometimes the same failure reaches further, to the manufacturer of a defective tire, brake, or coupling, which opens a products-liability claim on top of the negligence case, exactly the kind of complex, expert-driven litigation these cases can become. A rollover caused by shifting cargo can reach the people who loaded or secured it, the shipper or the loading company. Each of these is a separate thread with its own proof and its own insurance, and pulling them apart takes engineers, reconstructionists, and the resources to do the work. That is the nature of a serious truck case, and it is why it belongs in the hands of a firm prepared for it.
The deadline
For a crash on or after March 24, 2023, Florida gives you two years to sue under Fla. Stat. 95.11(5)(a). In a truck case the clock that matters most is shorter: the carrier only has to keep some logs and inspection records for a matter of months, so the real deadline for protecting the evidence is measured in weeks, not years.
A jackknife, rollover, or blowout is never just bad luck, and I treat it as the failure it usually is. I bring in the reconstruction and engineering to find the real cause, and I follow it wherever it leads, to the carrier’s maintenance, to a component manufacturer, or to the company that loaded the trailer wrong. I represent injured people, not trucking companies, and I build these cases with the experts and resources they demand rather than accepting the easy story that no one was to blame.
Common Questions
What is a jackknife?
It is when a truck's trailer swings out to the side until the truck and trailer form a sharp angle, like a folding pocketknife. It usually happens when the driver brakes too hard or too late, often because of speeding, following too closely, or poorly maintained brakes, and the swinging trailer can sweep across several lanes.
What causes truck rollovers?
Most rollovers come from speed in a curve or ramp, a load that was too high or improperly secured, or an abrupt steering correction. A loaded trailer has a high center of gravity, so a speed that is fine for a car can tip a truck. Cargo that shifts because it was loaded wrong makes it far worse.
Who is at fault for a tire blowout?
Often the carrier. Tire failures usually trace to underinflation, worn or mismatched tires, overloading, or skipped inspections, all of which the federal maintenance rules are meant to catch. A blowout that resulted from neglected upkeep is the carrier's responsibility, not bad luck.
Aren't these just accidents that happen?
Rarely. A jackknife, a rollover, and a blowout almost always have a cause the rules address: speed, braking, loading, or maintenance. The truck's black box, the maintenance records, and the load documents usually show which one, and whether the carrier or driver failed to do something they were required to do.
What evidence is used in these cases?
The engine control module for speed and braking, the maintenance and tire records, the cargo and loading documents, the driver's logs, and a reconstruction of the physics of the loss of control. As with every truck case, the truck and its data have to be preserved before they are gone.

This page is general information about Florida and federal law governing truck crashes, not legal advice, and it does not create an attorney-client relationship. These cases arise under the Federal Motor Carrier Safety Regulations on maintenance and operation (49 C.F.R. Parts 392 and 396) and Florida negligence law, including Fla. Stat. 768.81 and 95.11(5)(a). Every case is different, and past results do not guarantee a similar outcome. The hiring of a lawyer is an important decision that should not be based solely on advertisements.
