Book Only What You Can Prove: Carrier Selection After Montgomery

The old carrier check was built for a quieter world

For years, a broker could treat carrier selection like a quick screen: confirm authority, glance at insurance, maybe look at a safety snapshot, then move the load. That workflow survived because the market rewarded speed and because the liability picture felt distant from the dispatch desk.

That world is gone.

The Supreme Court's May 14, 2026 decision in Montgomery v. Caribe Transport II, LLC changed the operating posture for freight brokers. The Court held that state negligent-hiring claims against brokers are not blocked by FAAAA preemption when the claim concerns motor vehicle safety. Justia summarizes the holding plainly: a claim that one company negligently hired another to transport goods falls within the safety exception to FAAAA preemption. See the case summary from Justia.

This does not mean every bad outcome creates broker liability. State law still matters. Facts still matter. The carrier still owns its own conduct. But the practical question for a broker is no longer whether a carrier had a DOT number. The question is whether the broker can show a reasonable selection process before the truck moved.

The new standard is not more paperwork. It is better memory.

A carrier check has two jobs.

First, it should help the team make the right call in the moment. Second, it should preserve the reason for that call after memories fade, inboxes move on, and a claim file asks what happened.

That second job is where most freight teams are weakest. They do the work, but the proof is scattered across tabs, screenshots, load notes, emails, and dispatch chat. When the record is fragmented, the process looks thinner than it was.

A defensible carrier-selection record should answer five questions without detective work:

• Was the carrier authorized to operate for the load type?
• Was the required insurance or filing evidence visible at the time of booking?
• Were safety signals reviewed, not ignored?
• Were identity signals checked for chameleon or contact-reuse risk?
• Was the final decision timestamped with the evidence the team actually saw?

That is the difference between checking a carrier and proving a carrier was checked.

Authority is a starting line, not a finish line

Active authority matters. It is also only the first layer.

The trap is treating authority as a binary pass. A carrier can be active and still carry risk that deserves review. The profile may show thin tenure, recent authority movement, insurance volatility, out-of-service signals, crash patterns, shared contact information, or a mismatch between the carrier's public identity and the lane being booked.

A strong workflow separates hard stops from review items.

Hard stops are signals that should block dispatch until resolved: inactive authority, out-of-service status, missing required coverage, cancelled filing posture, or a clear identity mismatch.

Review items are not automatic rejections. They are signals that require judgment: a young authority, elevated inspection history, low fleet size for a complex lane, shared phone or address patterns, or safety data that looks acceptable in one table but weak in context.

The point is not to reject more carriers. The point is to stop pretending all active carriers are equally safe to book.

Insurance proof should be read like evidence, not decoration

Insurance and filing data often get reduced to a green check. That is not enough.

The useful questions are specific:

• What filing is present?
• Who is the insurer?
• What date is attached to the evidence?
• Does coverage appear adequate for the operation?
• Is the status active, cancelled, pending, or unclear?

A broker does not need a museum of screenshots. A broker needs a record that shows the source, the posture, and the time the posture was reviewed.

When LongMile surfaces insurance posture, the goal is not to make the page look complete. The goal is to make the booking decision auditable.

Safety data needs translation

Raw safety tables are hard to use under pressure. They are also easy to misuse.

A dispatcher moving fast can see a lot of numbers and still miss the decision. Vehicle out-of-service percentages, driver out-of-service percentages, crash counts, safety rating, inspection volume, and BASIC hints all matter differently depending on the carrier's size and operating profile.

The practical question is not, Is there any negative signal? The practical question is, Does the signal change the booking decision?

A better safety review does three things:

1. It separates normal noise from material risk.
2. It explains why a signal matters.
3. It keeps the source context attached to the final decision.

That is why a single score can help, but only if the score opens into evidence. A number without an explanation is just a decoration. A number with the underlying filings, inspections, crash context, authority posture, and identity checks becomes a decision tool.

Chameleon risk belongs before the score

Fraud and identity reuse are not side issues. They are often the part of carrier selection that decides whether a clean-looking profile is actually bookable.

The signals are familiar to anyone who has been burned:

• Multiple entities sharing a phone number.
• A business address reused across thin or recently opened authorities.
• Officer, email, or contact patterns that connect unrelated-looking companies.
• A carrier identity that does not match the lane, equipment, or history being represented.

These signals should appear before the team commits to the load. If identity risk sits below the fold, in a separate tab, or in someone's memory, it will be missed when the board gets hot.

A carrier-selection record should show not just that the carrier existed, but that the carrier's identity made sense.

The record should be useful before it is defensive

The best compliance systems do not feel like compliance systems. They feel like better operations.

A broker should be able to open a carrier profile and know what to do next:

• Book.
• Review with a manager.
• Ask for more documentation.
• Do not move the load.

That is the operational value. The defensive value comes later because the same workflow creates a record: what the team saw, what mattered, and when the decision was made.

If a tool only creates paperwork after the fact, the team will avoid it. If it helps them make the booking call faster, the record becomes a natural byproduct of good work.

A practical carrier-selection standard

A freight team does not need a 40-step ritual for every load. It needs a repeatable standard that scales with risk.

For normal loads, the standard can be simple:

1. Confirm authority and operating posture.
2. Verify insurance or filing evidence.
3. Review safety score and material safety signals.
4. Check identity and chameleon indicators.
5. Save the decision record.

For higher-risk loads, add review depth:

• New carrier or thin history.
• Expedited freight.
• High-value cargo.
• Cross-border or complex routing.
• Any mismatch between the carrier's stated capability and public data.
• Any identity reuse signal.

The standard should not depend on the most careful dispatcher being on shift. It should be visible, repeatable, and fast enough to use on a bad morning.

What LongMile is building for

LongMile is built around one belief: freight teams should not have to choose between speed and proof.

The product takes raw federal records, filing posture, safety data, identity signals, and source freshness, then turns them into a profile a broker can use before dispatch. The score matters, but the score is not the product. The product is the evidence around the score.

The ideal carrier profile does not bury the operator in tabs. It answers the booking question first, then shows the proof.

That is the new bar.

The takeaway

Montgomery did not invent the need for careful carrier selection. Good brokers already knew the work mattered.

What changed is the cost of having no record.

The winning freight teams will not be the teams with the most screenshots. They will be the teams with the clearest process: authority checked, insurance reviewed, safety translated, identity verified, decision saved.

Book only what you can prove.
