The 48-Hour Clock: What to Do With Your Carrier File the Minute You Hear About an Accident

The call came on a Wednesday morning. An operations manager I know — seven years in freight, good instincts — heard from a shipper that one of their carriers, MC-1247893 (DOT-3567102), had been in a serious accident on I-70 outside Columbus. Two people hospitalized. The truck had moved three of their loads in the past four months.

His first question to me: "Should we call the carrier to see what happened?"

My answer: Don't call anyone. Go pull your carrier file right now.

He found it. A SAFER snapshot dated three months before the last load. An insurance confirmation with a handwritten date in the margin. A T-call note that said "spoke with dispatch — truck looks good" but no date, no name of who he spoke with, no documented MC pull at the time of that call.

That file was about to be subpoenaed, and it wasn't ready for what was coming.

What happens to your file in the first week

Post-Montgomery v. Caribe Transport II, LLC (decided May 14, 2026), the Supreme Court made it clear that FAAAA preemption doesn't shield freight brokers from state-law negligent selection claims. That ruling changed the calculus on something brokers rarely think about: how fast plaintiff's counsel moves after a serious accident.

In significant cases — fatalities, catastrophic injuries, multi-million-dollar exposure — plaintiff's attorneys often retain accident reconstruction firms within 48 hours. Preservation letters go out to everyone in the chain within the first week. Those letters — sometimes called litigation hold letters — are a formal demand to stop destroying, altering, or purging any records related to the incident. If you receive one, you're already on the timeline.

The problem: normal business operations in the first 48 hours can contaminate your record before the hold letter arrives. A dispatcher calls the carrier to find out what happened and documents it in the TMS. Someone pulls a fresh SAFER snapshot "to see if anything changed." An internal email thread starts speculating about whether the carrier was properly vetted. All of that is now discoverable. All of it happened after the accident. None of it is helpful.

You have about 48 hours to get your file in order before it becomes everyone else's problem too.

Stop doing two things immediately

Do not go back and update the file. The instinct is understandable. Your file has a SAFER snapshot from three months ago and no clear timestamp on the T-call note — so you want to add context, fill in dates, annotate. Don't. Whatever your file contains right now is the record. The moment you add anything after learning about the accident, you create a credibility issue that your defense counsel cannot work around: did this entry exist before the accident or after? A plaintiff's lawyer who finds a vetting note that looks freshly written will make that question the centerpiece of your deposition.

Do not delete anything. Under 49 CFR § 371.3, brokers are required to retain records of each transaction — carrier name, date of shipment, bill of lading number, compensation amounts — for three years. That retention obligation isn't contingent on whether the load resulted in a claim. If you've been routinely purging carrier files before the three-year mark, that's a problem worth solving now, not after you've gotten the preservation letter. And if your standard practice is to purge, the fact that you deleted this carrier's file shortly after hearing about the accident is going to look exactly like what it might or might not be.

Do three things instead

Snapshot the file as it exists right now. Export every document, every note, every system record associated with this carrier. Print to PDF, ZIP the directory, whatever your system supports — and make sure the export carries a system-generated timestamp showing when you created it. The goal is to lock the record. If your vetting platform automatically updates carrier status when FMCSA data changes, or if your TMS timestamps get modified during normal record maintenance, you want a point-in-time capture before any of that happens.

Document when and how you first heard about the accident. Write it down now: date, time, who called, what they said. This is simple but it matters. "When did you first learn about the accident involving MC-1247893" is a question that comes up in every deposition in cases like this. You want to answer it from a note you wrote within an hour of the call, not from memory eighteen months later.

Call your attorney before you call the carrier. I know how this sounds. Most brokers have never called an attorney over a carrier incident, and it feels like you're escalating something that might not need escalation. But the call you make to the carrier in the first 48 hours can create obligations and admissions you don't intend. If the carrier says "your dispatcher told us to push through that delivery window even though the driver was running long" — that conversation now happened. Get counsel first. It doesn't mean you expect to be sued. It means you're treating a serious accident like a serious situation.

Run an honest audit of what you actually have

Once the file is locked and you've briefed the right people, you need to understand exactly what your file contains. Not what you wish it contained — what's actually there.

• Is there a dated SAFER snapshot at or near the time of the last load?
• Is there documentation of insurance verification, and does it have a system-generated timestamp or just a date you added manually?
• Is there a contemporaneous note from a T-call — and does it record who you spoke with, when, and what you confirmed?
• If you used a third-party vetting tool, can you export a report with a system-generated audit trail showing when you ran the check?

Whatever's missing, note it now. Not to construct a cover story — you can't fix the gap and you shouldn't try — but because your defense counsel needs an accurate inventory before they can help you. "Here's what I have and here's what I don't" is the starting point for a real defense. Walking into that first attorney call without knowing your own file is not.

What the carrier's file will show in discovery

When this goes into litigation, one of the first things plaintiff's counsel will request is the carrier's own accident register — the document motor carriers are required to maintain under 49 CFR § 390.15, which covers every accident involving death, bodily injury, or a tow-away for three years. If the carrier had prior incidents that never made it into SAFER's crash table — sub-threshold events, incidents that weren't reported — they're in that register.

If you vetting this carrier never included a request for the accident register — and almost no broker makes this request — you're going to be asked why. The answer "I didn't know it existed" is true for most brokers and it's not a good answer.

The practical takeaway isn't retroactive. You can't go back and fix the vetting you already did. But if the accident register becomes part of this case, and it shows a pattern of prior incidents you had no way of knowing about through standard FMCSA checks, that's context your defense counsel needs to understand before trial.

The 49 CFR § 371.3 issue most brokers don't know about

The broker records retention rule — 49 CFR § 371.3 — is one of those regulations that sits in the background until it suddenly matters. It requires brokers operating under federal authority to maintain a record of each transaction for three years, containing the carrier's name and address, the bill of lading or freight bill number, the amount of compensation received, and the amount of any freight charges collected or remitted.

What the regulation doesn't specify is format. Paper, digital, exported PDFs — all acceptable. What it does require is that the records be complete, retained for three years, and available for inspection.

Post-Montgomery, this retention rule takes on a different practical meaning. Any load you tendered in the past three years to a carrier who is now in litigation is potentially subpoena-able. If you retained complete files per § 371.3, you have a foundation to work from. If your records are inconsistent — some loads with full files, some with nothing, some with records you can't locate — the first accident call is when that inconsistency becomes a problem you have to solve under pressure.

Why 48 hours and not 48 days

I've talked to brokers who heard about a crash on a Tuesday and didn't treat it urgently until they got a letter from plaintiff's counsel three weeks later. By then, a dispatcher had called the carrier twice and documented those calls in the system. Someone had pulled a new SAFER snapshot and updated the carrier's record. An internal email chain existed that contained phrases nobody would want to defend in deposition.

All of that happened during three weeks of normal business. None of it was intentional. All of it is now discoverable and all of it happened after the accident.

In serious accidents — fatality, permanent injury, commercial vehicle — plaintiff's counsel moves fast because the evidence degrades and the defendants can be slow to understand what's at stake. The 48-hour window matters because by hour 72, you've already made decisions you can't unmake.

How I document this

When I hear about a serious accident involving a carrier I've worked with, here's the immediate sequence:

1. Export and timestamp the carrier file as it currently exists. No changes.

2. Document the date, time, and source of how I first learned — handwritten in my notebook if nothing else.

3. Brief ownership and legal counsel — not the carrier, not the shipper, nobody outside the organization until legal weighs in.

4. Pull the FMCSA record and screenshot it with today's date — the accident investigation will update the SAFER record over the coming weeks; the Day 1 snapshot is a separate data point.

5. Create a clean incident log — separate from the carrier file itself — where every post-accident action is recorded chronologically.

The goal is not to manufacture a defense. It's to have an accurate, timestamped record of what you had before the accident and what you've done since learning about it. If you did your job right during vetting, that record is your defense. If you didn't, your lawyer needs to know the truth before opposing counsel does.

I'm not a lawyer and I'm not giving legal advice. What I'm doing is telling you what I've seen go wrong and what I wish more brokers had in place before the call came. If a serious accident involves a carrier you've worked with, make the first call to your attorney. Make the second call after you've looked at your file.
