A wide turn or "squeeze play" accident happens when a big rig swings left before turning right, and a vehicle or cyclist moves into the gap on the truck's right. As the trailer tracks inward it crushes them against the curb. Liability usually rests with the driver for failing to signal or check the right-side blind spot, and with the carrier for inadequate training.
Because a tractor-trailer's trailer wheels track a tighter arc than its cab, commercial drivers are trained to swing wide before completing a right turn — sometimes moving left into an adjacent lane first. This creates a well-documented hazard known as the "squeeze play": a vehicle or cyclist alongside the truck, believing the truck is turning left or simply not anticipating the maneuver, gets trapped and crushed between the trailer and the curb as the truck completes its turn.
The underlying mechanism is called off-tracking: the rear wheels of a long trailer cut inside the path the tractor takes, by several feet on a 53-foot trailer. Off-tracking is physics, not negligence. What turns a wide turn into a claim is the driver's conduct around it — whether the maneuver was signaled, whether the right-side blind spot was checked before the trailer began tracking in, and whether the driver was trained on the turning behavior of the specific trailer being pulled.
How wide turn accidents happen
- The squeeze play at intersections. A car pulls up beside a truck signaling right, not realizing the truck must swing left first, and is squeezed against the curb or a fixed object.
- Failure to check the No-Zone before turning. The same right-side blind spot involved in blind spot accidents hides vehicles and pedestrians directly in the turn path. FMCSA's Our Roads, Our Safety guidance on large blind spots identifies the right side as the largest No-Zone on a tractor-trailer, extending across more than one lane.
- Inadequate or misaimed mirrors. 49 CFR § 393.80 requires rear-vision mirrors on both sides giving a view along each side of the vehicle. A mirror knocked out of adjustment and never reset is a maintenance and training failure, not bad luck.
- Turning too sharply for the trailer length. A driver who misjudges the trailer's swing radius can run the rear wheels over a curb, into a crosswalk, or into a vehicle in the adjacent lane.
- Pedestrians and cyclists in crosswalks or bike lanes are especially vulnerable, since they are often positioned exactly where a trailer's rear wheels track during a tight turn.
Who is liable?
- The driver — failing to signal the wide-turn maneuver, failing to check mirrors and blind spots before turning
- The trucking company — inadequate training on turning procedure for the specific trailer length in use
- A municipality — in rare cases, intersection design that doesn't accommodate commercial turning radii may add a government defendant, with its own shorter notice deadlines
The carrier's own records frequently decide the case. 49 CFR Part 391 governs driver qualification and requires the carrier to maintain a qualification file — including road test and training documentation. Where that file shows a driver never demonstrated competence with a 53-foot trailer, the claim moves from the driver's momentary inattention to the carrier's hiring and training practice, which is both better insured and harder to defend. A carrier's prior violation record is public through the FMCSA Safety Measurement System. See who can be held liable.
What evidence proves the claim
Squeeze-play cases turn almost entirely on lane position and signal timing in the final seconds — facts that eyewitnesses reconstruct badly and cameras record precisely:
- Intersection and traffic signal camera footage, which shows the truck's position and turn signal. This is the highest-value evidence in the case and is typically overwritten within days.
- Nearby business security cameras, which often cover the corner from an angle the city camera does not.
- The truck's electronic control module, for speed and steering input through the turn.
- Driver qualification and training records under Part 391, on off-tracking procedure for the trailer in use.
- The trailer length and configuration, which determines how far the rear wheels tracked inward.
Because the footage that decides these cases has the shortest life, preservation demands should go out within days. Learn what to do next, see how this evidence is obtained on our FMCSA regulations & evidence page, and start a free case review.
Injuries and compensation
Squeeze-play victims are crushed rather than struck, which produces a distinct injury pattern: crush injuries to the lower body, amputation, spinal cord injury, and for cyclists and pedestrians caught under the trailer wheels, frequently wrongful death. See what a truck accident settlement covers.
