The most pronounced shift in this dataset is not in vehicle mechanical compliance but in driver out-of-service rates. The driver OOS rate sat at 4.57% in January 2024 and climbed to 7.15% by July 2025, a rise of roughly 57% in 18 months, before easing modestly to 6.56% in January 2026. Over the same period, the vehicle OOS rate moved far less, ranging between 13.5% and 16.1% without a clear directional trend. This divergence between the two OOS series is the central feature of the data and suggests the compliance pressure is concentrated in driver-related violations rather than equipment defects. April 2025 illustrates the gap clearly: driver OOS events totaled 20,457 compared to 11,700 in April 2023, a 75% increase, while vehicle OOS events rose 36% over the same comparison. The overall violation rate has also edged higher. The trailing 12-month average of 56.5% compares to 55.3% in the prior 12-month period, and July 2025 posted the highest single-month violation rate in the dataset at 57.35%. The February 2026 observation covers only 55,734 inspections against a typical monthly run rate above 220,000, indicating partial-month or partial-reporting data that should not be interpreted as a trend break. Inspection volumes have grown over the window; several months in mid-2025 exceeded 260,000 inspections, levels not seen earlier in the series, which means absolute OOS counts are rising faster than rates alone would imply. The pattern of rising driver OOS rates is consistent with enforcement prioritization shifts or changes in the driver labor pool composition, though the data alone does not establish causation. Placed in the five-year context of roughly 9.5 million total inspections in this dataset, the recent driver OOS acceleration represents a meaningful departure from the relative stability that characterized 2022 through mid-2024. ### Key Statistics 7.15% Driver out-of-service rate July 2025 (series high) 4.57% Driver out-of-service rate January 2024 (recent series low) 24,450 Driver OOS events July 2025 56.5% Average violation rate (inspections with at least one violation) Trailing 12 months 55.3% Average violation rate Prior 12 months 15.2% Average vehicle out-of-service rate Trailing 12 months 6.6% Average driver out-of-service rate Trailing 12 months 474,194 Total violations recorded July 2025 (monthly high in dataset) 9,476,766 Total roadside inspections Full 60-month window 86,438 Total out-of-service events (vehicle + driver) July 2025 2,686,451 Total inspections Trailing 12 months 16.1% Vehicle out-of-service rate August 2025 (recent high) Cite this data AlphaLoops.
