Car Hauler Truck Accidents in Illinois: Unsecured Vehicles, Loading Ramps and Carrier Liability

Were you struck by a vehicle that broke loose from a car hauler, or hurt when a loaded carrier hit a low Chicago viaduct? You may be entitled to compensation from more than one party — and the evidence that proves it starts to disappear within days.

A car hauler, also called an auto transporter or car carrier, is a tractor-trailer built to stack passenger vehicles on hydraulic decks, commonly carrying somewhere between seven and ten cars depending on the rig and the load. That design puts tons of cargo several feet above the roadway, held in place by straps, chains, and wheel nets that must be applied correctly every single time.

We understand that a collision with one of these rigs can be a catastrophic and traumatic event for you and your family. This guide explains the federal securement rules that govern car carriers, why height strikes happen on Chicago corridors, and how liability splits among the driver, the motor carrier, and the terminal that loaded the vehicles.

Most semi-trailers enclose their cargo inside a box, so a loading mistake usually stays inside the trailer. A car hauler carries its cargo in the open, and every vehicle on the upper deck becomes a potential projectile if a tiedown slips or a deck fails.

Car carriers also come in several configurations, and each one carries its own risks. Some of the most common setups include:

• Stinger-steer haulers. The tractor itself carries vehicles over the cab, with the coupling mounted low behind the rear axle so the trailer can sit closer to the ground and fit more cars under the height limit.
• High-mount haulers. These use a conventional fifth-wheel position, which simplifies the coupling but generally leaves less vertical room for loaded vehicles before the rig reaches its legal height.
• Wedge and gooseneck trailers. Smaller car haulers pulled by heavy-duty pickups often carry three or four vehicles and are frequently run by small operators, which can affect how much training and oversight the driver received.

Because of that open, stacked design, car hauler crashes tend to follow a handful of recognizable patterns. These include but are not limited to:

• Vehicle ejection. A car breaks free of its straps or chains on a curve, during hard braking, or after a pothole impact, and falls into adjacent or following traffic.
• Overpass and viaduct strikes. A top-deck vehicle clips a bridge or railroad viaduct, sending debris onto the roadway and sometimes stopping the rig abruptly in a live lane.
• Deck and ramp failures. A hydraulic deck drops or a rear loading ramp is left extended or unsecured, creating a low, poorly lit hazard for following drivers.
• Rollovers. Loaded upper decks raise the center of gravity, and a rig taken too fast through a ramp or interchange can tip in a way similar to tanker truck rollovers.
• Rear-end and underride impacts. The sloped rear of a car carrier can sit at an angle that allows a passenger vehicle to slide beneath it, a risk we cover in depth in our guide to underride crashes.

All of these crash types share one feature — they usually trace back to a decision made before the rig ever left the terminal. This is why the loading process, and the rules that govern it, sit at the center of almost every car hauler case.

The Federal Motor Carrier Safety Regulations devote an entire subpart of 49 CFR Part 393 to cargo securement, running from § 393.100 through § 393.136. Those rules apply to commercial motor vehicles in interstate commerce, and Illinois extends the federal regulations to many intrastate carriers through 625 ILCS 5/18b-105, with certain exceptions.

Every load must first meet the general performance criteria in § 393.102. In plain terms, the securement system must withstand forces of 0.8 g decelerating forward, 0.5 g accelerating rearward, and 0.5 g sideways — the kinds of forces a rig experiences in a hard stop or an emergency swerve.

On top of those general criteria, § 393.128 sets specific rules for automobiles, light trucks, and vans that individually weigh 10,000 pounds (4,536 kg) or less. Here is how that section applies to a typical car carrier load:

• Two-tiedown minimum. Each vehicle must be restrained at both the front and rear against lateral, forward, rearward, and vertical movement using a minimum of two tiedowns.
• Designated mounting points. Tiedowns attached to the structure of the vehicle being hauled must use the mounting points designed for that purpose, rather than a suspension arm or exhaust hanger chosen for convenience.
• Wheel restraints. Straps and nets that fit over or around the wheels are permitted, but they must still provide restraint in the lateral, forward, rearward, and vertical directions.
• Heavier vehicles. Any vehicle over 10,000 pounds falls outside § 393.128 and must instead be secured under the heavy vehicle and equipment rules in § 393.130.

The equipment itself is regulated as well. Under § 393.104, tiedowns and their components must be in proper working order without damaged or weakened parts that would affect performance, and § 393.108 governs the working load limits those components must carry.

Securing the load once at the terminal does not end the driver's obligations. Under 49 CFR § 392.9, the driver must inspect the cargo and securement devices within the first 50 miles of a trip, then again whenever the driver changes duty status, after three hours of driving, or after 150 miles, whichever comes first.

Keep in mind that regulations are amended over time, and the current text published on the federal eCFR controls over any summary — including ours. That said, a car that leaves a deck on the Dan Ryan Expressway is strong evidence that at least one of these duties was not met.

Federal law does not set a uniform height limit for trucks, so each state sets its own. In Illinois, 625 ILCS 5/15-103 caps vehicle height at 13 feet 6 inches, and car haulers are routinely loaded to sit close to that ceiling.

The difficulty is that legal height and available clearance are two different numbers. Chicago is laced with older railroad viaducts, and many of them post clearances below 13 feet 6 inches, along with lower-level streets such as Lower Wacker Drive where posted clearances limit tall vehicles.

Car haulers face a particular risk on these corridors for several reasons. Some of them include:

• Variable load height. A carrier loaded with sedans on Monday may carry tall SUVs or pickups on the upper deck on Tuesday, changing the rig's overall height from trip to trip.
• Deck positioning. If the upper deck is not fully lowered and locked after loading, the top vehicles can ride higher than the driver expects.
• Navigation shortcuts. Consumer GPS apps may route a truck onto city streets that truck-specific routing software would avoid.
• Last-mile deliveries. Dealer and auction deliveries often pull a full-size car carrier off the interstate and onto neighborhood streets lined with low viaducts.

Accordingly, a driver who knows the load is near 13 feet 6 inches has a duty to measure it, plan around posted clearances, and stay on designated truck routes. When a strike happens, the debris — glass, body panels, sometimes an entire vehicle — lands on the drivers, cyclists, and pedestrians below.

Height and speed hazards are not limited to city streets, either. Interchange ramps and toll plazas along the interstates carry their own clearance and congestion risks, which we discuss in our coverage of Tri-State Tollway crashes.

Car hauler cases rarely involve a single defendant. The vehicles may be loaded at a port, rail ramp, auction yard, or dealership by one crew, hauled by a driver employed or leased by a second company, and arranged through a broker that never touches the load.

Potentially liable parties include but are not limited to:

• The driver. A driver who skips the inspections required by § 392.9, drives too fast for a loaded rig, ignores posted clearances, or exceeds hours-of-service limits may be directly negligent — fatigue issues we explore in our guide to driver fatigue crashes.
• The motor carrier. Under respondeat superior principles, a carrier is generally responsible for the negligence of drivers acting within the scope of their work, and it can also be directly liable for negligent hiring, training, supervision, or maintenance under 49 CFR Part 396.
• The parties to a lease arrangement. Many car haulers are owner-operators leased to a larger carrier, and the federal leasing rules in 49 CFR Part 376 can bear on which company controls the equipment and answers for the driver.
• The loading terminal or shipper. When a terminal crew, rather than the driver, positions and straps the vehicles, that crew and its employer may share fault for an improper securement under ordinary negligence principles.
• The equipment manufacturer. A failed hydraulic cylinder, cracked deck, or defective ratchet may support a product liability claim against the company that designed or built it.
• The broker. In some cases, a broker that selected a carrier with a poor safety record may face a negligent-selection claim, although this area of law is unsettled and depends heavily on the facts.

Illinois then divides responsibility among these parties. Under the modified comparative fault rule in 735 ILCS 5/2-1116, an injured person may recover as long as their own fault is not more than 50 percent of the proximate cause, with damages reduced by their share.

What's more, 735 ILCS 5/2-1117 affects how much each defendant must actually pay. Generally, a defendant found less than 25 percent at fault is only severally liable for damages other than medical expenses, which is why identifying every responsible party — not just the most obvious one — matters so much.

Liability questions also overlap with other failure modes. A car hauler that loses a steer tire, or a driver who is on a handheld phone, raises the same carrier-responsibility issues covered in our guides to tire blowout crashes and trucker phone violations.

The evidence in a car hauler case is split across the carrier, the terminal, and the equipment itself. Much of it is electronic or routinely overwritten, so it must be identified and preserved quickly.

Here is a list of the records that often matter most:

• Electronic logging device data. ELD records show when the rig stopped, which can confirm or refute whether the § 392.9 securement checks happened on schedule — a point we cover in our guide to ELD data preservation in Chicago.
• Engine control module data. The truck's ECM may record speed, braking, and throttle position in the seconds before a load shift or impact.
• Bills of lading and condition reports. Car carriers typically document each vehicle's position on the trailer and its condition at pickup, which helps reconstruct where a loose vehicle was riding.
• Terminal loading records. Work orders, crew assignments, and yard video can show who strapped each vehicle and when.
• Driver vehicle inspection reports. Reports prepared under 49 CFR § 396.11 may reveal prior complaints about decks, hydraulics, or tiedowns.
• The physical tiedowns. Straps, chains, ratchets, and wheel nets should be preserved for expert inspection before a carrier repairs or discards them.

As a result, a written preservation demand sent early can make the difference between a provable claim and a disputed one. Our step-by-step guide to the first 72 hours after a semi crash explains what injured people and their families can do in those early days.

Time limits in Illinois are strict. Most personal injury claims must be filed within two years under 735 ILCS 5/13-202, and wrongful death actions generally carry a two-year limit under 740 ILCS 180/2.

Be aware that a shorter deadline may apply if a local public entity shares fault, for example over a missing or inaccurate clearance sign. The Local Governmental and Governmental Employees Tort Immunity Act, 745 ILCS 10/8-101, generally requires those claims to be filed within one year.

If you or a loved one were injured, the damages available in a car hauler case may include:

• Medical expenses. Current and future treatment, including care for traumatic brain injuries and the crush and amputation injuries that can occur when a falling vehicle strikes a passenger compartment.
• Lost income. Wages already missed and any reduction in your ability to earn in the future.
• Pain and suffering. Physical pain, emotional distress, and the loss of enjoyment of life that follow a life-altering crash.
• Property damage. Repair or replacement of your vehicle and personal property.

Every case is different, and no lawyer can promise a particular result. Our guides to Illinois truck accident settlement value and the Chicago settlement timeline explain the factors that shape both the amount and the pace of a recovery.

While nothing can undo what happened, we also know that you may be entitled to compensation from every party whose choices put that load on the road. Our team works with accident reconstruction and cargo-securement experts, and we move to preserve evidence in the first 30 days.
