DOT Blitz Week, Broker Edition: What Your Carriers Are Going Through and How It Hits Your Book

Last Wednesday I had three carriers I'd booked loads with miss their delivery windows. None of them called to tell me ahead of time. All three eventually responded that their truck or driver had been put out-of-service at a Roadcheck inspection, somewhere between the pickup and the consignee. One was OOS for three days while a brake-system issue was fixed. The other two were back on the road within four hours but had to be re-routed around the inspection delay.

That's a normal blitz week if you book carriers across the US. The brokers I know who handle blitz weeks well treat them as a calendar event with predictable disruptions. The brokers who get caught by them treat them as a surprise every year.

CVSA's 2026 enforcement calendar is now set and partly behind us: **International Roadcheck was May 12–14** (just ended), **Operation Safe Driver Week is July 12–18**, **Brake Safety Week is August 23–29**, plus a single-day unannounced Brake Safety Day that floats somewhere in the year. Three more enforcement spikes between now and Labor Day. Here's what each does to your book and how to plan around them.

What Roadcheck did in May (and what's now in your carrier files)

International Roadcheck is 72 hours of heightened enforcement across the US, Canada, and Mexico. This year's vehicle focus was **cargo securement**; the driver focus was **ELD tampering and falsification of duty status records**. Historically, the inspections produce ~20% vehicle OOS and ~5% driver OOS, plus a heavier-than-usual volume of citations that don't quite hit OOS thresholds but still flow into CSA.

Three downstream effects that hit your business right now:

One: the CSA records of the carriers you've been booking are about to update. FMCSA's SMS data refreshes on a monthly cycle. Inspection events from May 12–14 will show up in carrier records sometime in the next 30–60 days, then start affecting BASIC percentile calculations. A carrier you booked through Roadcheck week who picked up a Vehicle Maintenance OOS is going to look meaningfully different on your next vetting pull than they did last month — and that difference stays in their record for 24 months.

Two: late deliveries this week are mostly carrier-side, not service-failure. When a truck or driver is parked at a scale, the load is parked too. Some of the broker rage I see at the end of blitz weeks comes from inexperienced dispatchers treating OOS-related delays as carrier negligence. They're not — they're enforcement events. The right move is to know which of your carriers got hit, document the OOS in their file, and use it as part of your forward-looking carrier evaluation.

Three: the OOS event affects how you should re-vet that carrier next time. A single-event OOS for a brake adjustment that was corrected and the carrier is back on the road in four hours is one thing. A pattern of OOS findings across multiple inspections, or a chronic OOS for the same root cause, is another. The diligence question is "is this a one-off operational miss, or is this evidence of a deeper safety-management problem?"

What's coming July 12–18: Operation Safe Driver Week

This is the BEHAVIOR week. Inspectors focus on roadside-observed driver conduct: speeding, lane changes, following too close, distracted driving, seat belt use, impaired driving. Less weighing-station, more enforcement-on-the-move. Officers in patrol cars looking for actionable behavior.

What this does to your book:

• Capacity tightens in your busy lanes. Drivers who get cited (or worse, OOS'd) for behavior are off the road for that day or longer. Spot-market rates typically rise 5–8% during Safe Driver Week, more on lanes with heavy enforcement presence (Texas-California, the Northeast Corridor, I-40).
• Driver-side BASIC alerts spike. Unsafe Driving and (to a lesser extent) Driver Fitness BASIC categories see a surge of violations during this week, which flows into the SMS over the following months. If you have carriers with already-elevated Unsafe Driving percentiles, expect the next refresh to make them worse.
• The carriers that pass clean send you a signal. Carriers whose drivers DON'T get cited during Safe Driver Week have safety culture. They're the carriers worth booking heavier loads with going forward.

What's coming August 23–29: Brake Safety Week

Brakes are the single most-cited vehicle OOS category. Year after year. Brake Safety Week is the week inspectors do extra-deep Level I inspections with emphasis on brake adjustment, ABS lights, hose condition, slack adjuster stroke.

What this does to your book:

• Bigger OOS impact than Roadcheck. Brake Safety Week typically produces vehicle OOS rates above the Roadcheck average because the focus is so narrow. A carrier that passes Roadcheck might still fail Brake Safety Week.
• More multi-day delays. Brake repairs that need parts can take 2-3 days. Capacity on lanes where carriers get parked tightens harder than during Safe Driver Week.
• The Vehicle Maintenance BASIC is going to move. Carriers with vehicle-maintenance issues get exposed during this week. Your post-week vetting pull on those carriers will show it.

Plus the unannounced **Brake Safety Day** — one calendar day somewhere in 2026, location and date not pre-announced. Same enforcement intensity as the August week, no warning.

A concrete scenario

You're a broker, you have a high-value load tendering on August 25 — middle of Brake Safety Week. A carrier you've booked twice before, MC-1247893 / DOT-3567102, quotes the load at a rate below market. Authority is two years old, BASICs clean except for Vehicle Maintenance at 49% (below threshold, but not great). Their last roadside inspection 4 months ago found an out-of-adjustment brake (not OOS at the time, but a citation).

What do you do? The default-broker move is "tender, hope for the best, deal with delays if they happen." The post-Montgomery move is different:

1. **Reconsider the timing.** If the load can move on August 22 instead of August 25, do that. Tendering an at-risk carrier into Brake Safety Week is like loading a leaky boat in a storm.

2. **If timing is locked,** require the carrier to send a signed inspection record from the last 30 days as part of the safety attestation. Specifically the brake-adjustment status from their last DOT inspection or independent shop visit.

3. **Document the decision.** Carrier file should include: "Booked MC-1247893 for load LD-2026-0825 during Brake Safety Week despite Vehicle Maintenance BASIC at 49% based on the following mitigation: required and received recent brake-system inspection record; no out-of-adjustment findings as of 2026-08-18; carrier acknowledged increased enforcement window."

If the truck does get hit at a scale on the 25th, the file shows you knew about Brake Safety Week, vetted the carrier specifically against that risk, required additional documentation, and made a reasoned tender decision. That's a defensible file. The alternative — "didn't think about it, just booked" — is the negligent-selection plaintiff's argument written in advance.

The attestation language for blitz weeks

The standard pre-load safety attestation you should already be collecting (pre-trip done, driver qualified, vehicle safe, cargo secured, etc.) covers the basics. For blitz weeks, two specific items I add:

For Roadcheck week (May 12–14):

"The driver, vehicle, and cargo on this load are in compliance with the cargo securement requirements of 49 CFR Part 393 Subparts I and J, and the driver's ELD records reflect actual duty status with no falsification or manipulation."

For Brake Safety Week (August 23–29) AND for any load tendered to a carrier with elevated Vehicle Maintenance BASIC during this period:

"The vehicle's brake system has been inspected within the last 30 days, all required adjustments have been performed, and the carrier is aware of no condition that would result in an out-of-service finding under the CVSA North American Standard Out-of-Service Criteria."

These representations are the carrier's independent statutory duty — they're not asking the carrier to commit to anything new. They're asking the carrier to AFFIRM, in writing, the facts only the carrier can speak to. Standard pattern: a false representation here is both a breach of your broker-carrier agreement AND an independent FMCSR violation. Combined, that's the post-Montgomery liability-shift mechanic.

The regulation, in plain English

CVSA enforcement weeks aren't an FMCSR section. They're cooperative enforcement initiatives between CVSA, FMCSA, state DOTs, and (during Roadcheck) Transport Canada and Mexico's SCT. The underlying authority is FMCSA's general safety-enforcement mandate under 49 U.S.C. § 31100 et seq. The OOS criteria CVSA uses are documented in the CVSA North American Standard Out-of-Service Criteria handbook (revised April 1 each year).

What this means at load-tender time: blitz-week dates are PUBLIC, well in advance. There's no excuse for a broker to be surprised by them. If your file shows you booked through a blitz week without acknowledging the increased risk, the plaintiff's lawyer will ask why.

How I document this

For every load tendered during a CVSA enforcement week, the carrier file includes:

1. **The enforcement-week designation** (e.g. "Tendered during CVSA Brake Safety Week, 2026-08-23 to 2026-08-29").

2. **The carrier's CSA snapshot** as of the day of tender, with explicit note of any BASIC at or near threshold relevant to the week's focus (Vehicle Maintenance for Roadcheck and Brake Safety Week; Unsafe Driving and HOS for Safe Driver Week).

3. **The week-specific attestation** the carrier signed (cargo securement / brake system / driver behavior).

4. **A rationale paragraph** for tendering during the enforcement window — what mitigation steps were required, what alternatives were considered.

The brokers who do this aren't being paranoid. They're being the brokers who win the negligent-selection deposition when it eventually happens. After Montgomery v. Caribe Transport II eliminated FAAAA preemption as an early exit, the file IS the case.
