Over the past three years, Vermont weigh stations and roadside inspection points have processed 24,211 commercial vehicle inspections. That's a large dataset. And buried in those numbers is a specific picture of what's failing on the roads in Vermont—and what that means for operations running through the state.
Here's the headline: Vermont's out-of-service rate is 20.2%. That's three percentage points above the national average of 17.6%. What does that mean? When an inspector finds a violation in Vermont, it's more likely to be serious enough to warrant pulling a vehicle from service. That's not a small distinction. It tells you something about the condition of trucks being inspected, or the enforcement intensity, or both.
Where the Violations Cluster
The violation breakdown reveals what inspectors are actually finding. Of 29,559 total violations documented, 19,909 were vehicle violations. That's 67% of everything written up. Vehicle violations generated 4,528 out-of-service citations.
Driver violations—logbook falsification, improper licensing, safety restraint violations—totaled 8,653, with 1,435 resulting in OOS. Hazmat violations were rare: 238 total, 48 OOS.
The picture is clear: mechanics, not behavior, drive the shutdown rate. The failures are in the trucks themselves: brake defects, lighting problems, tire separations, coupling failures, structural issues. These are exactly what 49 CFR Part 396 is designed to catch. More importantly, they're preventable.
Conversion Rate: Violations to OOS
One specific metric worth examining: 20.2% of violations found in Vermont result in out-of-service status. The national average is 17.6%.
This means Vermont violations are disproportionately serious. You can read this a few ways. Vermont inspectors might apply the standards more strictly. Vermont trucks might have more severe defects. Or some combination. Regardless of cause, the practical implication is the same: when something goes wrong at the scale house in Vermont, it's more likely to stop your truck.
Vermont averaged 1.22 violations per inspection over the 37-month period (August 2023 through August 2026). That's actually lower than the national average. But of those violations, a higher percentage trigger OOS status. In other words, Vermont finds fewer problems per truck, but the problems it finds are more serious.
What This Means for Operations
If you operate in Vermont, the data points to one control: vehicle maintenance. When two-thirds of violations are mechanical, not behavioral, that's where your prevention effort goes.
You can't prevent inspections. But you can prevent the defects inspectors find. Brakes, lights, tires, couplings, structural integrity—these aren't subjective standards. They're measurable. You can test them before an inspector does. You can establish maintenance thresholds based on what inspectors are actually citing.
The vehicles being pulled from service aren't failing abstract regulations. They're failing specific mechanical tests. If your roadside OOS rate is running high, the solution usually starts with the truck itself.
Key Takeaways
- Vermont's 20.2% out-of-service rate exceeds the national 17.6%
- Vehicle violations comprise 67% of all violations (19,909 of 29,559)
- When vehicle violations occur, 22.7% result in OOS status
- The pattern is consistent across three years of inspection data
- Maintenance defects dominate over driver or operational violations
Next Steps
The numbers tell the pattern. To actually reduce OOS rates, you need the specifics: Which violations code are cited most frequently? Which vehicle components fail repeatedly? What maintenance gaps are showing up in the data?
That granular information exists in Vermont's roadside inspection records. You can see exactly what inspectors are finding, match it to your fleet's maintenance practices, and close the gaps before the scale house finds them.
