The trailer folding across three lanes looks like bad luck. A jackknife accident almost always begins with locked wheels and lost traction, though, and federal rules address both.
Below, we explain what causes the fold, which duties the driver owed, and why the carrier’s favorite defense deserves testing.
Why a Jackknife Accident Points Toward the Brakes
First, understand the mechanics. When the drive wheels or trailer wheels lock, traction disappears and the trailer keeps pushing forward around the hinge.
Federal rules target that exact failure. Under 49 CFR 393.55, air-braked truck tractors built after , and trailers built after , must carry antilock brakes.
One detail matters enormously. Those systems include a malfunction indicator lamp, so a fault announces itself on the dash long before a crash.
Therefore, the question becomes documentary. Did the lamp show a fault, did the inspection report note it, and did anyone repair it?

Meanwhile, 49 CFR 392.14 speaks directly to traction. Drivers must use “extreme caution” when snow, ice, sleet, fog, mist, rain, dust, or smoke affects visibility or traction.
The rule goes further than caution. Speed “shall be reduced,” and operation must stop entirely once conditions turn sufficiently dangerous.
Georgia says much the same thing. O.C.G.A. § 40-6-180 bars any speed greater than reasonable and prudent given actual and potential hazards.
So rain is not an excuse. Instead, it triggers a duty the driver either met or ignored.
Why “It Came Out of Nowhere” Deserves Testing
Carriers reach for sudden emergency. Georgia excuses a driver who faced genuine peril with no time for reflection.
One limit does real work, though. A driver who helped create the emergency cannot claim its protection.
Conflicting evidence sends it to a jury. Consequently, speed, following distance, and brake condition in the final seconds decide whether the defense survives.
What the Load Contributes
An empty trailer rides light. Less weight over the axles means less grip. So a deadhead run folds more easily than a loaded one.
