The Pre-Trip Attestation Is Evidence — Most Brokers Don't Know That

A driver signs a piece of paper before every trip. Says the truck is roadworthy. Nobody in the broker world thinks much about that signature — it's the carrier's business, not ours. Except after Montgomery, it became our business too.

Let me explain what I mean.

What the regulation actually says

Under 49 CFR § 396.13, before driving a commercial motor vehicle, a driver must: (a) review the previous driver vehicle inspection report (DVIR), and (b) sign that report if defects were noted and that those defects were repaired or that repair was not necessary. That's not optional. It's required by federal regulation on every trip.

Paired with that is § 392.7, which requires the driver to satisfy themselves that the vehicle is in safe operating condition before moving it. And § 396.11, which requires the driver to complete a written report covering at minimum brakes, steering, lights, tires, horn, windshield wipers, mirrors, and coupling devices. After each trip.

The carrier then has to retain those DVIRs for three months, per § 396.11(c).

So what? The carrier does the paperwork, the driver signs it, the broker sees none of it. That's mostly true. But here's where it gets interesting.

What high Vehicle Maintenance BASIC scores are actually telling you

The Vehicle Maintenance BASIC on SAFER doesn't measure whether a carrier does paperwork. It measures whether drivers and roadside inspectors are finding defects — brake issues, tire failures, lights out, coupling problems — during actual inspections. When that BASIC percentile is high (over 65, and definitely over 80), you're looking at a carrier where defects are surfacing in the field.

Now think about what that means for the pre-trip. Either the drivers are doing thorough pre-trips and consistently finding problems (the carrier has a real maintenance culture problem), or drivers are not doing thorough pre-trips and defects are getting caught by troopers on the side of the road instead. Both are bad. The second is worse.

I've talked to defense attorneys who've handled cases after Montgomery. One thing they told me: they always pull the DVIRs. Not from the broker — from the carrier, during discovery. What they're looking for is whether drivers were signing off on trucks that then got put OOS at a scale. If the truck failed inspection on a Tuesday and the DVIR from Monday shows "no defects found," that's a problem for the carrier. It's also a problem for the broker who tendered to that carrier while knowing their Vehicle Maintenance BASIC was at the 82nd percentile.

That last sentence is the part that changed after the Supreme Court's ruling in Montgomery v. Caribe Transport II, LLC. Before May 14, 2026, most courts in the 7th and 11th Circuits would have said the FAAAA preempts a broker's state-law negligence claim. Now that preemption argument is gone, unanimously. Justice Barrett's opinion makes clear that a broker's duty to exercise reasonable care in carrier selection is a legitimate state-law claim. The standard of care includes what you knew or should have known. A carrier's maintenance BASIC at the 82nd percentile is something you should have known.

A scenario worth sitting with

MC-1247893 / DOT-3567102. Running 28 power units out of Memphis. Dry van, primarily Midwest lanes. Their Vehicle Maintenance BASIC is at the 79th percentile. Their OOS rate for vehicle inspections is 14.8%, against a national average of around 20% — so not outright disqualifying on the surface. They've been operating for 26 months. Safety rating: not rated.

You look at that carrier and maybe you don't pass on them. 26 months of authority, MC is active, insurance showing current on L&I, bond in place. Reasonable broker could tender there.

Six weeks later, one of their drivers misses the pre-trip on a split trailer and the brake adjustment on the rear axle is way out of spec. There's a rear-end collision on I-55. A passenger in the struck vehicle dies. The suit names your brokerage alongside the carrier.

Plaintiff's attorney pulls discovery. Among the items they request: your carrier qualification file for MC-1247893. They find you screened the carrier and noted the 79th percentile VM BASIC. Your screening note says "borderline, tendered anyway." Now they're asking what additional due diligence you did given that specific BASIC score. Did you look at the underlying violation codes? Did you call the carrier? Did you ask about their DVP process?

Most brokers don't do any of that. Most brokers see a number and make a binary pass/fail decision. That's the gap that shows up in deposition.

What the violation codes under the BASIC actually contain

This is worth a minute because most brokers stop at the BASIC percentile number. If you drill into the underlying violations on FMCSA's SMS portal, you'll see the actual inspection items that produced the BASIC score. Brake adjustment violations. Brake lining and pad issues. Tire tread depth. Lighting. Coupling devices. These map directly to what a driver is supposed to catch on a pre-trip.

If a carrier's top violation category is brake adjustment defects, repeatedly, across multiple inspections at roadside — that tells you something specific. Not just that their maintenance is marginal, but that their pre-trip process is not catching brake adjustment before the truck rolls. That's a 49 CFR § 392.7 failure at the driver level, and it reflects on the carrier's internal compliance culture under § 396.3 (the carrier's duty to inspect, repair, and maintain vehicles).

This matters in a post-Montgomery world because "what the broker knew or should have known" now includes what the broker could have learned by looking one level deeper than the headline BASIC number. I'm not saying every broker needs to run a forensic audit on every carrier. I'm saying that if the headline number is elevated, you should look at what's underneath it before you decide to tender.

The "Conditional" rating carrier and the pre-trip

There's a specific scenario that keeps coming up in my conversations with attorneys: a carrier with a Conditional safety rating. Under 49 CFR Part 385, a Conditional rating means the FMCSA found the carrier did not have adequate safety management controls in at least one regulatory area. They found something. They documented it. The carrier kept running.

Here's the thing about Conditional carriers and pre-trip attestation: if the Conditional rating was issued based on maintenance violations (which is common), you're dealing with a carrier where the feds have officially documented that their vehicle maintenance practices are inadequate. That documentation exists in the FMCSA's investigation files. Their drivers are still going out every day and signing DVIRs saying the truck is safe.

Tendering to a Conditional carrier on a high-value lane or a time-sensitive shipment isn't automatically negligent. But it raises the bar on what you need to document about why you made that decision. "We checked and they were Conditional but their insurance was current" is not going to hold up if the accident involves a brake failure.

How I document this

When I'm vetting a carrier with a Vehicle Maintenance BASIC above 65, my screening record needs to include more than the BASIC number. Here's what I log:

The specific BASIC percentile and the date I pulled it. The top two or three underlying violation categories visible in SMS. Whether the OOS rate for vehicle inspections is above or below the national average. The carrier's safety rating. Any notes from a call with the carrier — even a quick T-call where I confirm they have an internal DVP process and that drivers are required to complete pre-trips on every dispatch. That last one matters. Carriers with a real pre-trip culture will tell you about it. Carriers that don't have one will usually get vague.

If the carrier is at the 80th+ percentile, I want to see that we had a conversation before I tender. Not because it guarantees nothing goes wrong. Because it shows I took an elevated risk signal seriously and did something about it other than just check a box.

The file should be timestamped and stored with the load. Not in a general "carrier file" that can't be linked to a specific shipment. The screening that matters is the screening you did for that load, that date. That's what survives deposition.

What this means in practice

The pre-trip attestation is not your responsibility. You're not the one signing the DVIR. But the maintenance culture that produces good pre-trips — or terrible ones — is something you can see signals of in the BASIC data before you tender. After Montgomery, ignoring those signals isn't a business decision, it's a legal exposure.

Brokers who've spent years treating carrier vetting as a checkbox exercise are going to have a rough time in deposition when the plaintiff's attorney asks them to explain what "79th percentile" meant to them at time of tender. The honest answer is usually "I didn't really think about it." That's not the answer you want to give under oath.

You don't have to be perfect. You have to be reasonable. And reasonable, post-May 2026, means understanding what the signals are actually telling you — including the maintenance signals that trace directly back to what a driver did or didn't do before pulling out of the yard.

How I document this (quick reference)

For any carrier with VM BASIC ≥ 65th percentile:

• Log the percentile, pull date, and the carrier's OOS rate for vehicle inspections.
• Open SMS and note the top 2-3 violation categories (be specific — "brake adjustment" is more useful than "brakes").
• Note the safety rating and when it was last issued.
• Record any direct communication with the carrier, including a T-call asking about their DVP/pre-trip process.
• Tie all of this to the specific load and date. Not the general carrier file — the load record.

If the carrier is Conditional and the Conditional rating was maintenance-related, add a note explaining why you tendered anyway. That note is your defense, written at the time, before anything went wrong.
