Who is at Fault When a Semi-Truck Makes a Wide Right Turn and Crushes a Passenger Car?
Navigating a 70-foot-long, 80,000-pound commercial semi-truck through a tight city intersection is a logistical nightmare. Because the rear wheels of a trailer do not follow the exact same path as the front wheels (a phenomenon known as "off-tracking"), truck drivers cannot make a sharp right turn from the right lane like a normal passenger car. Instead, they must swing wide to the left, occupying the middle lane, before pulling hard to the right to clear the curb. This creates a deceptive, wedge-shaped gap on the right side of the truck. When an impatient or unaware passenger car attempts to slide into this gap, the truck completes its turn, acting like a massive pair of steel scissors that crushes the car against the sidewalk.
This terrifying scenario is known in the trucking industry as a "Right Hook" accident. When the police arrive, the truck driver will almost always blame the passenger car, claiming the car illegally tried to pass on the right or entered their blind spot. However, commercial driving rules dictate exactly how a right turn must be executed. Determining who is at fault when a semi-truck makes a wide right turn and crushes a passenger car requires proving that the truck driver failed to "buttonhook" the turn properly to protect that right-side gap.
The CDL manual explicitly instructs drivers on how to turn right. They are supposed to use a "buttonhook" method: keeping the rear of the trailer tight to the right curb while the cab swings wide into the intersection, preventing cars from passing on the right. When a driver gets lazy, they use a "jug handle" turn: swinging the entire truck into the left lane *before* reaching the intersection, leaving the right lane completely wide open. The jug handle turn is considered a dangerous, improper maneuver because it practically invites cars to pull up beside the trailer.
Proving the Truck Driver's Negligence
To win a wide right turn case, a specialized plaintiff's attorney must prove that the truck driver created an inescapable trap. Liability is established through three key failures:
If the truck driver initiates a jug handle turn, they are technically leaving their lane of travel. Traffic laws dictate that a vehicle cannot turn right from a left or middle lane. If dashcam footage or witness testimony proves the driver swung completely out of the right lane without keeping their trailer tires close to the curb, they are at fault for abandoning their lane and then cutting back across it.
Commercial trucks are equipped with specialized fender mirrors and convex spot mirrors designed specifically to eliminate the right-side blind spot. Even if a passenger car enters the blind spot, the truck driver has a legal duty to check their mirrors constantly during the turn. Squeezing a car requires ignoring the mirrors for several seconds while the trailer closes the gap.
Most trucking companies apply bright yellow stickers to the back right corner of the trailer that read, "Caution: Makes Wide Right Turns." If the company failed to maintain these decals, or if they were obscured by mud, the victim can argue they were not provided adequate warning of the truck's intended maneuver.
Don't Accept the Blame
Insurance adjusters rely on the police report, and police often side with the truck driver in right hook accidents because the car appears to be illegally passing on the right. An attorney will use accident reconstruction, tire marks on the curb, and intersection cameras to prove the truck driver abandoned the lane and created a lethal trap.
