Wide Right Turns and Squeeze-Play Truck Crashes in Chicago: Who Is at Fault?

Have you ever pulled alongside a tractor-trailer at a Chicago intersection and watched it drift toward the centerline just before the light changed? If so, you have seen the opening move of one of the most common and least understood truck crashes on the city's grid.

Drivers call it the squeeze play. The truck swings left to buy room for a right turn, a gap opens along its passenger side that looks exactly like an open lane, and a car, a cyclist, or a delivery scooter moves into that space seconds before the trailer sweeps back across it.

What follows is almost always the same question. Who is at fault when a vehicle is crushed in a gap the truck itself created?

The answer rests on three things: physics that no tractor-trailer can escape, duties the driver accepted when they earned a commercial license, and video evidence that in many cases is overwritten within days. Keep in mind that those three elements run on very different clocks, and the one that expires fastest is usually the one that would have settled the argument.

A squeeze play unfolds as a sequence, and that sequence begins well before the truck starts to turn. The order matters, because liability attaches at a point most people overlook — the moment the driver chose to swing left instead of holding the curb.

The vehicle caught in the gap is rarely doing anything exotic. In most of these collisions the motorist is traveling straight, at ordinary city speed, occupying what appears to be a legitimate right-hand lane or a marked bike lane.

The pattern is consistent enough that a reconstruction expert can often read it off a few seconds of intersection footage. The typical stages include but are not limited to:

• The pre-swing. The tractor moves left, sometimes across the centerline, while the right turn signal is active. To a driver behind and to the right, that leftward drift reads as a left turn or a lane change.
• The false lane. The space between the trailer and the curb widens to roughly the width of a travel lane, and on Chicago arterials that space frequently overlaps a bike lane, a parking lane, or a right-turn-only lane that genuinely exists.
• The mirror interval. Between initiating the swing and committing to the turn, the driver has a window in which the right-side mirrors show the developing hazard. That interval is short, but it exists, and it is usually what decides the case.
• The sweep. The tractor turns right and the trailer's rear axles cut inside the tractor's path, closing the gap sideways rather than from behind.
• The pin. The occupant vehicle is forced into the curb, a light pole, a parked car, or a building line, often with the trailer's side or landing gear riding over the hood or roof.

Every stage in that sequence except the last one is controlled by the truck driver. That is what separates a wide-turn crash from a rear-end collision or a routine lane-change sideswipe, where fault often turns on who moved first.

It is also a distinctly urban crash. The expressway network produces a different profile entirely, closer to the high-speed patterns we cover in our guide to Tri-State Tollway truck crashes, while the squeeze play belongs to signalized corners with tight curb radii.

Offtracking is the reason a tractor-trailer cannot turn like a sedan. Because the trailer's rear axles pivot around a kingpin set well forward of the trailer's tail, those rear wheels follow a tighter arc than the steer axle and cut inside the corner the tractor just rounded.

The practical consequence is a swept path considerably wider than the vehicle itself. Highway design references model a standard interstate tractor-semitrailer with a minimum turning radius in the mid-forties of feet and an inside rear-wheel radius closer to twenty, which describes a swept path well over twenty feet across.

Chicago travel lanes generally run ten to twelve feet. As a result, a 53-foot trailer physically cannot complete a ninety-degree turn from a single lane at many of the city's older intersections, and no amount of driver skill changes that.

Here is the point that defense counsel would prefer you skip past. Offtracking explains why the turn must be wide; it does not explain why the swing must go left first.

Commercial driver training addresses the distinction directly. The standard commercial license curriculum instructs drivers to turn wide as they complete the turn while keeping the rear of the vehicle close to the curb, and it warns explicitly against turning wide to the left at the start, because doing so invites another driver to pass on the right.

Illinois law codifies the same instinct. Under 625 ILCS 5/11-801, both the approach for a right turn and the right turn itself must be made as close as practicable to the right-hand curb or edge of the roadway.

Read together, the training standard and the statute produce a clean liability question. Did the driver keep the trailer against the curb and take the extra room on the far side of the intersection, or did they open a lane-width gap on their right and then close it with fifteen tons of steel?

Note that curb radius matters to the analysis as well. Many Chicago corners predate modern design vehicles, so a carrier that routes 53-foot trailers through them without route planning has made a decision the jury is entitled to hear about.

A wide right turn is a planned maneuver executed at low speed. That is what makes the duty analysis in these cases comparatively clean, unlike a drift-out-of-lane event where the central question becomes impairment or driver fatigue.

Federal equipment rules give the driver the tools to see the hazard. 49 CFR 393.80 requires two rear-vision mirrors, one on each side, each with at least 10.75 square inches of reflective surface, positioned to show the driver a view of the road along both sides of the vehicle.

Most tractors in Chicago service carry considerably more than that minimum. A flat mirror, a convex spot mirror, and frequently a fender-mounted mirror cover the right side, and a growing share of fleets add side-object detection or camera systems that log an alert when a vehicle enters the right-side zone.

That equipment cuts both ways for the defense. If the mirrors and sensors were adequate and functioning, then the hazard was visible, and the case narrows to the simple question of whether the driver looked.

Signaling is a separate duty, and it is a lower bar than most people assume. 625 ILCS 5/11-804 requires a continuous signal during at least the last 100 feet traveled before the turn in business and residence districts, but a signal communicates intent only.

Remember that a turn signal does not reserve the space to the driver's right. Blocking the gap with the trailer does, which is precisely what the wide-at-completion technique is designed to accomplish.

Federal rules also fold state traffic law into the federal safety scheme. 49 CFR 392.2 requires that a commercial motor vehicle be operated in accordance with the laws of the jurisdiction in which it is operated, so an Illinois turning violation is simultaneously a violation of the federal regulations the carrier is audited against.

The carrier's obligations matter as much as the driver's conduct. Entry-level driver training standards at 49 CFR Part 380 cover vehicle control and space management, and the driver qualification file required by 49 CFR Part 391 frequently reveals whether this driver had prior turning or sideswipe events before the collision at issue.

These cases are won and lost on what the gap looked like from inside the cab. Physical evidence at the scene rarely answers that, because crush patterns show where the vehicles ended up rather than how the space opened.

Video does answer it. Chicago intersections are unusually well covered by a mix of municipal traffic cameras, transit vehicle cameras, private business and parking-garage systems, residential doorbell cameras, and other motorists' dashcams.

Retention is the problem. Many of those systems overwrite on a rolling cycle measured in days rather than months, and no operator has any obligation to preserve a file until somebody asks in writing.

The truck own data has a longer but still finite life. Under 49 CFR 395.22(i), a motor carrier must retain electronic logging device records and a backup copy for at least six months, a window our guide to ELD data preservation after a Chicago truck crash walks through in detail.

Other record classes run on their own timers. A carrier must retain up to eight supporting documents for each 24-hour on-duty period under 49 CFR 395.11, while the accident register required by 49 CFR 390.15(b) must be maintained for three years after each crash.

Engine control module data is the most volatile of all. ECM and telematics records can capture road speed, brake application, steering input, and throttle position in the seconds before impact, yet that data may be overwritten once the tractor returns to service, or simply lost when the unit is repaired or sold.

This is why a preservation letter goes out first and questions come later. Note that a spoliation claim is a poor substitute for the footage itself, and while Illinois courts recognize negligent spoliation as a theory, no court makes it an easy one.

Crash reports also tend to understate the pattern. These collisions are generally coded under broader headings such as turning right or same-direction sideswipe, so the squeeze play rarely appears in the data as its own category.

The standard defense in a squeeze-play case is that the injured party passed a signaling truck on the right. Expect that argument, because it is close to the only argument available once the trailer's path is established on video.

Illinois law does not treat passing on the right as an automatic bar. Under 625 ILCS 5/11-704, overtaking on the right is permitted in defined circumstances, including on a roadway with unobstructed pavement of sufficient width for two or more lines of moving vehicles in each direction, which describes most Chicago arterials.

Lane markings complicate the defense further. If the gap the truck created overlapped a striped bike lane, a right-turn-only lane, or a through lane, then the motorist or cyclist was occupying a lane the city painted rather than a space they invented.

Even where the injured party carries some responsibility, Illinois applies modified comparative fault. Under 735 ILCS 5/2-1116, a plaintiff's recovery is reduced in proportion to their share of the fault and barred entirely only if that share exceeds fifty percent.

Remember that comparative fault is a jury question, not a screening rule an adjuster applies over the phone. An early recorded statement is frequently the tool used to manufacture that percentage, which is why counsel routinely asks clients to route insurer calls through the firm.

Cyclists face a sharper version of the same fight. Illinois requires at least three feet of clearance when passing a bicycle under 625 ILCS 5/11-703(d), and a trailer that sweeps laterally across a marked bike lane during a right turn is difficult to reconcile with that requirement.

The first days after a squeeze-play collision matter more than they do in most crash types, precisely because the decisive evidence is video and video expires. Here is a list of the steps that protect your options:

• Get evaluated the same day, even if you walked away. Lateral crush injuries and head injuries frequently present hours later, and a same-day record removes the gap in treatment that insurers use to argue the harm came from something else.
• Photograph the intersection, not only the vehicles. Lane striping, curb radius, signal placement, and the final rest position of the trailer all establish the geometry that the reconstruction will depend on.
• Write down every camera you can see. Storefronts, light poles, parking structures, buses, and rideshare dashcams each hold a few days of footage, and the list is far easier to build at the scene than a month later.
• Decline a recorded statement until you have advice. The carrier's insurer will call quickly, and the questions are built around the passing-on-the-right defense described above.
• Capture the police report number, the USDOT number, and the trailer number. Tractors and trailers are often owned by different entities, and that split determines who receives the preservation demand.
• Send written preservation demands in the first week. Demands should reach the carrier, the tractor owner, the trailer owner, and every third party holding video.

Taken together, those six steps preserve the two things that decide a wide-turn case: the geometry of the intersection and the record of what the driver could see. Everything else in the claim can be reconstructed later.

Injury severity in these collisions runs to the extremes. Because the trailer closes sideways rather than from behind, an occupant vehicle can be pushed beneath the trailer in a side underride sequence, and even at low intersection speeds the rotational forces involved produce the kind of truck crash brain injuries that do not present at the scene.

The filing clock is generous compared with the evidence clock, though it is not forgiving. Illinois generally allows two years for personal injury under 735 ILCS 5/13-202 and two years for wrongful death under 740 ILCS 180/2, while a claim involving a local public entity can drop to one year under 745 ILCS 10/8-101.
