Understanding the Montgomery v. Caribe Transport II Decision for Illinois Truck Accident Victims

Personal Injury,Truck Accident - August 20, 2026 by Horwitz, Horwitz & Associates

Truck accident cases often involve more than just the driver behind the wheel. Depending on how a shipment was arranged, multiple companies may have played a role in putting that truck on the road. A recent unanimous decision from the U.S. Supreme Court has clarified an important question about when one of those companies (a freight broker) can be sued after a serious crash.

In Montgomery v. Caribe Transport II, the Court held that federal law does not automatically prevent injured people from bringing state-law negligent hiring claims against freight brokers. While the decision does not make brokers responsible for every trucking accident, it confirms that these claims can move forward when they fall within a state’s authority to regulate motor vehicle safety.

For Illinois truck accident victims, the ruling removes a significant legal obstacle that had previously prevented some negligent hiring claims from being heard.

What Happened in Montgomery v. Caribe Transport II?

The case arose from a devastating crash on Interstate 70 in Illinois in December 2017.

After experiencing mechanical problems, Shawn Montgomery pulled his vehicle onto the shoulder of the highway. While stopped, his vehicle was struck from behind by a tractor-trailer that had apparently left the roadway. The collision caused catastrophic injuries, including the amputation of Montgomery’s leg and permanent disfigurement.

The truck was operated by Caribe Transport II, an interstate motor carrier. The shipment itself had been arranged by freight broker C.H. Robinson Worldwide.

Montgomery alleged that C.H. Robinson should not have selected Caribe Transport II to haul the load because the company had previously received a “conditional” safety rating from federal regulators. According to the lawsuit, that rating identified deficiencies involving driver qualifications, hours-of-service compliance, and crash history.

Rather than focusing only on the trucking company, Montgomery argued that the broker had been negligent in choosing an allegedly unsafe carrier.

What Is a Freight Broker?

A freight broker is not the company that owns or operates the truck.

Instead, a broker arranges transportation by matching shipments with motor carriers. In other words, the broker helps connect companies that need freight moved with trucking companies that will transport it.

Because brokers select the carriers that perform the work, lawsuits sometimes allege that a broker failed to exercise reasonable care when choosing a motor carrier.

Why Was the Lawsuit Challenged?

C.H. Robinson argued that Montgomery’s lawsuit could not proceed because of the Federal Aviation Administration Authorization Act of 1994 (FAAAA), specifically 49 U.S.C. § 14501(c), which limits certain state laws relating to the prices, routes, or services of motor carriers and freight brokers.

The dispute centered on whether Montgomery’s negligent hiring claim fell within the statute’s motor vehicle safety exception found in 49 U.S.C. § 14501(c)(2)(A).

Both the federal district court and the Seventh Circuit Court of Appeals agreed with the broker’s position and dismissed the negligent hiring claim.

The Supreme Court, however, reached a different conclusion.

What Did the Supreme Court Decide?

In a unanimous opinion written by Justice Amy Coney Barrett, the Court concluded that the FAAAA contains an important exception that applied to Montgomery’s claim.

The law specifically preserves a state’s authority over motor vehicle safety. The Court explained that state common-law duties (such as the duty to exercise reasonable care when selecting a contractor for work that creates physical risks to others) are part of that safety authority.

The Court further concluded that a negligent hiring claim involving the selection of a trucking company concerns the operation of motor vehicles used to transport property. Because of that connection to motor vehicle safety, the claim falls within the statute’s safety exception rather than being automatically preempted.

As a result, federal law did not bar Montgomery from pursuing his negligent hiring claim against the freight broker.

What Arguments Did the Court Reject?

The broker raised several arguments for why the safety exception should not apply.

One concern was that allowing negligent hiring claims would effectively eliminate the FAAAA’s preemption protections. The Supreme Court disagreed, explaining that the safety exception applies only to state laws concerning motor vehicle safety. Other types of state regulation (such as laws governing carrier pricing or highway routing) remain subject to federal preemption.

The broker also argued that the Court’s interpretation created unnecessary overlap within the statute. The Court concluded that the different provisions could still operate together because route controls and weight restrictions may serve purposes other than safety.

Finally, the broker pointed to another section of the FAAAA involving intrastate shipping that does not contain the same safety exception. Although the Court acknowledged that the statutory structure raises questions, it emphasized that the language Congress actually enacted controlled the outcome.

A Separate Opinion Offered an Important Reminder

Justice Brett Kavanaugh, joined by Justice Samuel Alito, agreed with the Court’s result but wrote separately to explain that the issue was a close one.

He observed that Congress enacted the FAAAA primarily to promote economic deregulation of the trucking industry, not to eliminate state authority over motor vehicle safety.

At the same time, Justice Kavanaugh emphasized that the decision should not be read as exposing freight brokers to automatic liability. Brokers that act reasonably and select reputable motor carriers, he noted, should still be able to defend themselves successfully against negligent hiring claims.

What Does This Decision Mean for Illinois Truck Accident Victims?

The Supreme Court’s decision does not mean every freight broker is responsible for every truck accident.

Instead, it means that federal law does not automatically prevent injured people from bringing negligent hiring claims against brokers when those claims concern motor vehicle safety. Whether a broker is ultimately liable will still depend on the specific facts and evidence in each case.

For Illinois truck accident victims, the ruling is significant because it allows courts to evaluate these claims on their merits rather than dismissing them solely because of federal preemption.

The Bottom Line

Montgomery v. Caribe Transport II clarifies an important aspect of truck accident litigation. The Supreme Court unanimously held that the FAAAA’s preemption provision does not automatically shield freight brokers from state-law negligent hiring claims involving motor vehicle safety.

For injured victims, the decision preserves the opportunity to argue that a broker failed to exercise reasonable care when selecting a motor carrier. It does not guarantee success, nor does it impose liability in every case. Instead, it ensures that these claims may be heard under applicable state law rather than being barred at the outset by federal preemption.
