    Analysis

    · as of September 15, 2026

    Highlights

    • Driver out-of-service rate reached 7.5% in July 2026, more than double the 4.68% recorded in April 2023.
    • The trailing 12-month average driver OOS rate of 7.1% is 270 basis points above the prior 12-month average of approximately 4.9%.
    • April 2026 posted a 59.39% violation rate, the highest single-month figure in the 60-month dataset.
    • Total inspections in the trailing 12 months reached 2,562,951, down from 2,936,498 in the prior 12-month period.
    • Vehicle OOS rate has held in a narrower band of 13.3%–16.5% over five years, while the driver OOS rate has roughly doubled since mid-2023.

    The most pronounced shift in the dataset is not in violation rates or inspection volumes but in driver out-of-service rates, which have nearly doubled over roughly two years without a corresponding move in vehicle OOS rates. The driver OOS rate averaged approximately 5.0% through most of 2022 and 2023, then began climbing steadily from early 2025, reaching 7.12% in July 2025 and remaining elevated through the most recent months with a trailing 12-month average of 7.1%, compared to roughly 4.9% in the prior 12-month period. Vehicle OOS rates, by contrast, have stayed within a comparatively tight range: the trailing 12-month average is 15.7%, versus approximately 14.9% in the prior period, a much smaller proportional shift. This divergence between driver and vehicle OOS trends is the clearest structural change visible in the data. The overall violation rate has also drifted upward. In Q1 2026, the three-month average violation rate was approximately 57.6%, compared to roughly 55.0% for Q1 2025, a year-over-year increase of around 2.6 percentage points. April 2026 recorded the dataset's peak violation rate of 59.39%, and several subsequent months remained above 58%, levels not seen earlier in the series. The volume picture is more mixed. Monthly inspections in 2026 have generally run in the 215,000–256,000 range, with the two partial months at the beginning and end of the series excluded from rate comparisons, and total trailing 12-month inspections of 2,562,951 are below the 2,936,498 logged in the prior period, suggesting enforcement activity by count has not expanded uniformly even as rate-based measures have risen. The persistent elevation in driver OOS rates is consistent with tighter Hours of Service and licensing enforcement priorities, though the data alone cannot establish cause. Viewed against the full five-year window of roughly 11.2 million inspections and 18.4 million violations, the recent driver OOS escalation represents a structural departure from the relatively stable 4.6%–5.3% band that characterized the 2022–2024 period.
