One in Three Trucks Failed. What the 2026 CVSA Blitz Number Means for Your CSA Score and Your Insurance Renewal.

What Actually Happened During Blitz Week and What the Numbers Mean The 2026 CVSA International Roadcheck ran May 12 through May 14, a 72-hour enforcement initiative across the United States, Canada, and Mexico. The surrounding DOT Blitz Week extended from May 10 through May 17, producing 15,952 total inspections and the 32.

8 percent out-of-service rate that is the subject of this article. One accuracy point worth establishing before the analysis: CVSA stated that final official results were still being finalized as of mid-May, as Transport Topics reported in its Roadcheck coverage. The 32.

8 percent figure reflects the full blitz week data tracked through FMCSA’s inspection system and reported by inspection data aggregators, compared to CVSA’s official 2025 Roadcheck result of 18. 1 percent over 56,178 inspections.

On Day 1 of the 2026 event, FMCSA inspection records showed 1,580 inspections, 2,637 violations, and 496 out-of-service orders, a 31. 4 percent OOS rate from day one, already substantially above the 2025 full-event benchmark. The 2026 focus areas were ELD tampering and cargo securement on the vehicle side.

But as The Brake Report noted in its Roadcheck coverage, brake system failures, tire violations, and lighting defects generated the highest volume of actual OOS orders. Focus areas signal where inspectors spend additional time. They do not narrow what inspectors check.

A Level I inspection is a 37-step procedure covering every critical system on the truck and every component of the driver’s operating qualification. Trucks were not failing disproportionately because of ELD issues. They were failing because of the violations that always produce OOS orders: brakes, tires, and lights.

There is also a significant contextual factor in the 2026 blitz numbers.

Drivers who were uncertain about their credentials or operating status had reason to avoid inspection sites during the blitz, which means a selection effect may have reduced the denominator of well-compliant trucks available at weigh stations during the event period while leaving the numerator of trucks with issues proportionally higher.

This does not fully explain a jump from 18. 1 percent to 32. 8 percent, but it is part of the honest picture. What the number means, regardless of the specific mix of causes, is that roughly one in three trucks inspected during the enforcement period had at least one violation serious enough to ground it on the spot.

Every one of those violations is in FMCSA’s system. How Blitz Week Violations Become CSA Points and How Those Points Move Your Score The first thing to understand about CSA scoring is that every violation from blitz week enters FMCSA’s Safety Measurement System exactly as every other roadside inspection violation does. Roadcheck is not a separate category.

The inspections are logged, the violations are coded, and the points accumulate in the relevant BASICs. The SMS scores carriers see in the FMCSA SMS public portal are calculated on a sliding 24-month window with time weighting.

Violations in the most recent six months carry the highest weight, violations from seven to 12 months carry a reduced weight, and violations from 13 to 24 months carry the lowest weight before aging off.

Out-of-service violations generally carry higher severity weights than non-OOS findings, and multiple violations within a single inspection can increase the overall impact on a carrier’s score. The seven BASICs and the violations that feed them are specific. Brakes are the primary driver of the Vehicle Maintenance BASIC.

Tire condition and tread depth violations also feed Vehicle Maintenance. Lighting violations, specifically inoperative required lights, feed Vehicle Maintenance. Hours-of-service violations feed the HOS Compliance BASIC. ELD falsification or tampering violations, the 2026 driver focus area, feed the HOS Compliance BASIC directly.

Cargo securement violations feed the Cargo-Related BASIC. FMCSA does not publish the full severity weight tables publicly, but the general principle is documented across multiple compliance resources: OOS violations carry a severity multiplier of 2.

0 in the SMS calculation, meaning a violation that grounds the truck scores twice as heavily as the same type of violation that does not produce an OOS condition.

A carrier who received multiple OOS violations in a single blitz week inspection, which is common given that brake, tire, and light issues often travel together, is looking at a significant point accumulation in the Vehicle Maintenance BASIC that will show up in their SMS score for the next 24 months.

The BASICs percentile ranking is the number that matters for insurance purposes. The SMS calculates each carrier’s violation rate per inspection relative to all other carriers in a similar category, producing a percentile score from 0 to 100. A carrier in the 75th percentile in Vehicle Maintenance scores worse than 75 percent of comparable carriers.
