Negligent Carrier Selection: What Brokers and Shippers Need to Know

By CarrierLens Compliance Team • Last updated: 2026-05-19

The legal doctrine of negligent carrier selection holds that a freight broker, shipper, or freight forwarder can be held liable for damages caused by a motor carrier when the hiring party knew — or should have known — that the carrier had safety deficiencies at the time of selection. In 2026, the Supreme Court significantly expanded broker exposure under this doctrine, creating an urgent compliance issue for every licensed broker and in-house logistics team in the United States.

What Is Negligent Carrier Selection?

Negligent carrier selection is a tort claim under state law. It holds that a party who hires a motor carrier has a duty of reasonable care in making that selection — specifically, a duty to review the carrier's publicly available safety record before booking a load. When a carrier with known safety deficiencies causes injury, death, or property damage, the hiring party can be joined as a defendant on the theory that their negligent selection of that carrier was a proximate cause of the harm.

The key evidence in these cases is almost always FMCSA public data: the carrier's safety rating, CSA BASIC scores, crash history, and operating authority status at the time of the load. Plaintiffs' attorneys routinely pull this data for the date of the incident and compare it to what was available at the time of booking. Brokers who booked carriers with Conditional safety ratings, CSA scores above alert thresholds, or elevated crash histories without documentation of their review are in a difficult evidentiary position.

Montgomery v. Caribe Transport II (2026): What Changed

For years, freight brokers defended negligent carrier selection claims by arguing that the Federal Aviation Administration Authorization Act (FAAAA) preempts state tort law claims related to broker services. Courts were divided on whether this preemption applied to negligent hiring claims. The First and Ninth Circuits held that it did; the Fifth and Eleventh Circuits held that it did not.

In Montgomery v. Caribe Transport II, No. 24-1238 (2026), the Supreme Court resolved the split, holding that the FAAAA preemption does not bar state-law negligent carrier selection claims against freight brokers when the broker's selection of an unsafe carrier was the proximate cause of injury or death. The Court distinguished "service" regulations (which are preempted) from safety-based tort liability arising from a specific carrier selection decision (which is not).

The practical effect of the ruling is nationwide: freight brokers in all 50 states are now fully exposed to state negligent carrier selection tort claims, with no FAAAA preemption defense available. Plaintiffs' attorneys, who had been waiting for this ruling, began filing an increased volume of negligent selection claims immediately following the decision.

What Constitutes Adequate Carrier Vetting After Montgomery

The ruling does not define a specific standard of care for carrier vetting — that is developed through case law and expert testimony in individual cases. However, courts and expert witnesses have consistently identified the following elements as minimum reasonable due diligence:

  1. FMCSA operating authority verification — Confirming the carrier holds active, authorized operating authority in the correct category at the time of booking
  2. Safety rating check — Reviewing any formal safety rating and not booking Unsatisfactory-rated carriers
  3. CSA BASIC score review — Reviewing all six BASIC category percentiles relative to FMCSA alert thresholds
  4. Crash and inspection history review — Noting any recent crash history, particularly fatal crashes
  5. Insurance verification — Confirming the carrier maintains at least the FMCSA minimum BIPD insurance
  6. Documentation of the review — Creating a contemporaneous record of what was checked, what was found, and who made the booking decision

Brokers who can produce contemporaneous vetting documentation for the specific load and carrier involved are in a significantly stronger legal position than those who must reconstruct their process from memory or general policies.

The Importance of Contemporaneous Documentation

In negligent carrier selection litigation, the timing and specificity of documentation matters enormously. A general policy document stating "we check FMCSA before booking" is far less valuable than a timestamped vetting certificate for the specific carrier, reviewed by a named employee, on the date of the booking decision.

Courts look for:

Manual processes — printing screenshots, saving PDFs, recording notes in a spreadsheet — can satisfy these requirements but are inconsistent and difficult to maintain at scale. Purpose-built systems like CarrierLens BrokerShield generate this documentation automatically for every vetting session and store it in a permanent, searchable audit log.

Who Is at Risk Beyond Licensed Brokers

While freight brokers are the primary defendants in most negligent carrier selection cases, the doctrine extends to any party that exercises meaningful control over carrier selection:

Insurance Is Not a Substitute for Due Diligence

Many brokers assume that carrier liability insurance requirements in their carrier agreements eliminate their vetting obligation. This is incorrect. Insurance provides financial coverage if an accident occurs, but it does not eliminate the broker's independent duty of care in carrier selection. Courts have held that requiring a carrier to carry insurance is not equivalent to exercising due diligence regarding the carrier's safety fitness — particularly when publicly available FMCSA data showed the carrier was unsafe at the time of booking.

Frequently Asked Questions

What is negligent carrier selection?
Negligent carrier selection is a legal tort claim under which a freight broker, shipper, or freight forwarder is held liable for damages caused by a motor carrier they hired when that carrier had known safety deficiencies at the time of booking. The claim holds that the hiring party knew — or should have known — that the carrier was unsafe, and that selecting them anyway was negligent. Evidence used to establish the carrier's dangerous condition typically includes FMCSA safety ratings, CSA BASIC scores above alert thresholds, crash history, and operating authority status — all of which are publicly available and expected to be reviewed by any competent broker.
What did the Supreme Court decide in Montgomery v. Caribe Transport II?
In Montgomery v. Caribe Transport II, No. 24-1238 (2026), the Supreme Court held that the preemption provisions of the Federal Aviation Administration Authorization Act (FAAAA) — which generally preempt state laws related to broker services — do not bar negligent hiring tort claims against freight brokers where the broker's selection of an unsafe carrier was the proximate cause of injury or death. The ruling resolved a circuit split and significantly expanded broker and shipper exposure to state-law negligent carrier selection claims. The practical effect is that brokers who cannot document a reasonable carrier vetting process are now exposed to multi-million-dollar personal injury verdicts when a carrier they selected causes an accident.
What carrier vetting documentation protects brokers from negligent selection claims?
To build a defensible vetting record, brokers should document: (1) the FMCSA operating authority status at time of booking; (2) the carrier's safety rating; (3) CSA BASIC scores and whether any exceeded alert thresholds; (4) crash and inspection history reviewed; (5) insurance verification (BIPD minimum confirmed); (6) the identity of the person who performed the check; and (7) the timestamp of the check. Timestamped, carrier-specific vetting records stored in a system of record are far more defensible than after-the-fact reconstructions. CarrierLens generates signed, timestamped vetting certificates for every carrier vetting session.
Does checking a carrier's FMCSA safety rating protect a broker from all liability?
Checking a carrier's safety rating is necessary but not sufficient for a complete vetting defense. A carrier can have no safety rating (the default for most carriers who have not undergone a compliance review) and still have alarming CSA scores, a recent crash history, or authority issues. A complete vetting defense requires reviewing FMCSA operating authority, safety rating, all six CSA BASIC category scores relative to alert thresholds, crash data, and insurance status — and documenting that review with a timestamped record. Brokers who rely solely on 'they had a valid authority number' have lost negligent carrier selection cases.
Are brokers the only parties at risk for negligent carrier selection?
No. Shippers who exercise significant control over carrier selection — rather than delegating fully to a broker — also face negligent carrier selection exposure under the post-Montgomery legal landscape. In-house logistics teams at manufacturers, retailers, and distributors who select or approve specific carriers for freight movements should implement the same vetting discipline as licensed brokers: documented FMCSA safety checks, CSA score reviews, and timestamped records of the vetting session before booking or load tender.
