The Shipper Liability Problem: Why Your Carriers and Brokers Are No Longer Your Only Risk

Most of the post-Montgomery commentary has focused on freight brokers. That's understandable — the case was about a broker, and the holding most directly affects broker liability. But the legal theory that powered Montgomery is older and broader than the brokerage industry, and it applies just as forcefully to shippers. Companies that ship freight in the United States now face exposure on three distinct fronts, and most of them don't have a plan for any of them.

This article walks through the shipper liability landscape post-Montgomery: the direct-tender theory, the negligent-broker-selection theory, and the contractual-control theory. We'll explain each, look at the cases driving the trend, and finish with what your shipping department should be doing differently starting next Monday.

Three Theories of Shipper Liability

Theory 1: Direct Negligent Carrier Selection

If you, as a shipper, tender a load directly to a motor carrier — without going through a broker — you are in the shoes of the broker for liability purposes. The duty of ordinary care that Montgomery confirmed for brokers applies equally to shippers who select carriers directly. There is no special carve-out for "shippers." The theory is the same: you chose this carrier, you owed a duty to exercise reasonable care in choosing them, and if your choice fell below that standard, you are liable for foreseeable harms.

The FAAAA preemption argument was never available to shippers in the first place — the statute applies to motor carriers, freight forwarders, and brokers, not to the shipper-customer side of the equation. So shippers have been exposed to direct negligent-selection claims for years. Montgomery doesn't change that. What it does change is the climate: a unanimous Supreme Court decision affirming negligent-selection theory against the most preempted defendants will make the theory even more aggressive against shippers, who never had the preemption defense to begin with.

Practical takeaway: if your company tenders loads directly to carriers, you need a carrier-selection process that mirrors the one a broker would need post-Montgomery. Authority, insurance, safety rating, BASIC status, crash history, OOS rates, documented at the time of tender.

Theory 2: Negligent Broker Selection

The more interesting — and more rapidly expanding — theory is negligent broker selection. The argument runs like this: even if you used a broker, you chose the broker. A reasonable shipper exercises ordinary care in choosing transportation intermediaries the same way a reasonable broker exercises ordinary care in choosing carriers. If you tendered loads to a broker who themselves had no vetting process, no policies, no documentation, and no qualifications to safely match loads with carriers, you failed in your duty as a shipper.

This theory was already being tested before Montgomery. Several federal cases over the past three years have allowed negligent-broker-selection claims to survive motion-to-dismiss stages, and at least two have produced significant settlements. Post-Montgomery, the theory accelerates dramatically. Plaintiffs' attorneys reason: if a broker can be sued for not vetting carriers, then a shipper who hired the broker can be sued for not vetting the broker. The chain of duty extends back through the supply chain to whoever ultimately controls the choice of who hauls the load.

Practical takeaway: if you ship through brokers, you need a broker-vetting process. Real diligence. Documented. Auditable. Renewed annually.

Theory 3: Contractual Control / Joint Venture

The third and least-discussed theory is contractual control. When a shipper exerts substantial control over how its freight is moved — specifying carriers, specifying lanes, specifying drivers, specifying equipment — courts have sometimes found that the shipper and carrier have, in effect, a joint venture or principal-agent relationship. In those cases, the shipper can be vicariously liable for the carrier's negligence even without a separate negligent-selection finding.

The contractual-control theory is fact-intensive and depends heavily on the specific language of shipper-carrier or shipper-broker agreements. Shippers who include hard requirements about specific carriers, specific drivers, or specific routes are taking on more risk than shippers who delegate those choices to qualified brokers.

Practical takeaway: review your transportation contracts. If you are exerting carrier-specific control, you are taking on carrier-specific liability. That may be the right tradeoff for some loads, but you should make it deliberately.

What Plaintiffs Are Looking For

Plaintiffs' attorneys in trucking cases have a checklist. After they identify the carrier and the driver, they look upstream:

Who tendered the load? If a shipper tendered directly, the shipper is a defendant.

If a broker, who did the broker work for? The shipper that hired the broker is a candidate defendant under negligent-broker-selection theory.

What does the shipper's transportation policy look like? A robust policy with documented vetting practices is a defense. A nonexistent policy is an admission.

Did the shipper specify or require anything? Specific carriers, specific drivers, specific equipment, specific routes — any of these can support a contractual-control claim.

What's the shipper's insurance picture? Plaintiffs are not pursuing parties without recoverable assets. Large shippers are attractive defendants because they have deep liability coverage and balance sheets.

The Insurance Landscape

Most shippers carry general liability and commercial auto insurance. Neither typically covers negligent-selection claims arising out of transportation activities. The right product is transportation contingent liability insurance — a specialty product that covers shipper exposure when carriers cause harm.

Many shippers have this coverage; many do not. Even those who do are often underinsured for the post-Montgomery threat environment. Verdicts of $25 million, $50 million, $100 million are no longer outliers. Several recent verdicts have exceeded $500 million against trucking defendants.

If you are a shipper of any meaningful volume, talk to your broker or your insurance counsel about transportation contingent liability coverage. Verify the limits are adequate. Verify the policy responds to negligent-selection theories specifically.

The Specific Documentation Plaintiffs Will Demand

When a major accident happens on a load your company tendered, the discovery requests will arrive within weeks. Expect to be asked to produce:

• Your written transportation policy and any updates over the relevant time period
• Your broker-vetting documentation, including initial qualification files and annual renewals
• Communications with the broker for this specific load and over the prior 12 months
• Any internal audits of broker performance, including any noted deficiencies
• Carrier-specific documentation if you tendered directly or specified the carrier
• Your insurance policies and any tender of defense correspondence
• All emails referencing this load, this broker, this carrier, this driver
• Any prior incidents on loads involving the same broker, carrier, or driver
• Your Do Not Use list, exclusion list, or equivalent — if you have one. If you don't, that absence will be highlighted.

The pattern is the same as for brokers. The cases turn on what you can produce and what you cannot.

The Broker-as-Vendor Audit

A meaningful and increasingly common practice among sophisticated shippers is to audit their brokers the way they audit any other vendor. This typically includes:

Initial broker qualification. Verify the broker's operating authority, surety bond, errors-and-omissions coverage, and references. Review their written carrier-selection policy. Ask for documentation of how the policy is applied. Confirm they retain records.

Annual broker requalification. Refresh the qualification documentation annually. Verify nothing has lapsed. Ask for changes since the last review.

Performance metrics. Track each broker's claim frequency, claim severity, on-time performance, and incident history. Brokers with elevated metrics get extra scrutiny.

Compliance verification. Require that brokers document their carrier-selection process for every load. Require that they retain records. Some shippers require that brokers use a specific screening platform — and audit usage.

Contract language. Update broker contracts to require explicit compliance with carrier-selection due diligence, retention of records, indemnification for selection-based claims, and additional-insured status on the broker's E&O policy.

What This Means for Your Transportation Procurement

For shipping departments, the work post-Montgomery breaks into three buckets.

Bucket 1: Direct-tender loads. If you ever tender directly to a carrier — even occasionally, even for backhaul or expedited or critical loads — you need a carrier-vetting process equivalent to what a broker needs. Authority, insurance, safety rating, BASIC status, crash, OOS, documented at the time of selection. This is non-negotiable.

Bucket 2: Broker-tendered loads. The broker is the front line; you are the second line. Your broker-vetting process is your defense. Documented qualification, annual renewals, performance tracking, contract language.

Bucket 3: Specialty or controlled loads. If your business model includes any carrier-specific requirements — dedicated lanes, dedicated drivers, hazmat-specific routings, white-glove or high-value freight with mandated security carriers — you have additional contractual-control exposure. Talk to counsel about how to structure those relationships.

A Word About Small and Mid-Sized Shippers

Big shippers have the resources for procurement teams, compliance officers, and legal counsel. Small and mid-sized shippers often do not, and there's a temptation to assume the post-Montgomery world is a problem only for the Fortune 500.

That's wrong. Smaller shippers are arguably more exposed, because they have fewer redundant safeguards and less institutional knowledge. A single bad accident on a single tender can put a small shipper out of business if the verdict exceeds the company's net worth. Insurance is critical. Process is critical. Documentation is critical.

The good news: the same tools that have transformed compliance for brokers — automated screening, attestation collection, audit-trail generation — are equally available to shippers. A shipper that uses a platform like DOTScreener to vet carriers and brokers gets the same documented-due-diligence defense the broker community is building toward.

The Strategic Question

The deeper question for shippers post-Montgomery is what role transportation procurement should play in the company. For the past two decades, transportation has often been a cost-minimization function. Cheaper carriers, leaner brokers, less paperwork. Montgomery is forcing a re-balancing. The cheapest broker who has no documented vetting process is no longer the cheapest choice when you factor in litigation exposure. The cheapest carrier who is in Alert status on Unsafe Driving is no longer the cheapest choice when you factor in catastrophic claims.

Smart shipping departments are reframing transportation as a risk-management function as much as a cost function. The right broker is the qualified broker. The right carrier is the safe carrier. The right documentation is the documentation that defeats a claim three years later in front of a hostile jury.

The Bottom Line

Montgomery v. Caribe Transport II is a broker case in name. In reality, it's a transportation-liability case, and the legal theories it endorses apply with equal force to shippers. If your company moves freight in the United States — by any mode, in any volume — you have post-Montgomery exposure. The defense is the same as it has always been: documented, consistent, reasonable processes applied at the moment of every decision.

If you ship freight, here is your one-line homework: by Monday morning, identify the person in your organization who owns broker-vetting and carrier-vetting. Make sure they have a policy, a process, and the documentation infrastructure to prove the process was followed. If that person doesn't exist, appoint one this week.

Litigation post-Montgomery is not a matter of if. It is a matter of when and how prepared you are when it arrives.
