Nearly one in five commercial trucks on U.S. roads fails to meet basic roadworthiness standards—the top predictor of fatal accidents. As freight recovery accelerates, a backlog of deferred maintenance from the 2022–2026 recession is resurfacing. Enforcement data shows a 21.6% Vehicle Out-of-Service rate across 3.3 million inspections, resulting in over 700,000 vehicles removed annually. However, regulatory audits cover only 1.5% of carriers yearly, meaning the average carrier won’t face a full audit for 65 years. In April 2025, President Donald Trump issued an executive order targeting English proficiency and non-domiciled CDL irregularities to combat 'chameleon carriers.' A J.J. Keller study also indicates declining executive commitment to fleet safety culture. The full SONAR report explores maintenance feedback loops, regulatory shocks, leadership gaps, and predictive safety tools like OTRI, OTVI, and ELP Enforcement Index.
Nearly one in five commercial trucks currently on U.S. roads fails to meet basic roadworthiness standards – a metric that stands as the #1 predictor of fatal accidents.
Deferred Maintenance Crisis Amid Freight Recovery
As the freight cycle recovers and utilization rises, the industry is confronting a massive accumulation of deferred maintenance from the prolonged freight recession of 2022–2026. During that time, a squeeze on carrier margins forced widespread deferral of equipment upkeep. As high-frequency data confirms, that risk is now coming back online.
Enforcement Data Reveals Escalating Safety Risks
This maintenance crisis is showing up clearly in enforcement data. High-frequency SONAR indices, including the ELP Enforcement Index, track a tightening regulatory environment. The current Vehicle Out-of-Service (OOS) rate has hit 21.6% across 3.3 million inspections, resulting in over 700,000 vehicles being removed from the road annually.
Regulatory Enforcement Lag Exacerbates the Crisis
The risk is compounded by an enforcement lag. The system currently audits just 1.5% of carriers per year, meaning the average carrier will not face a comprehensive audit for 65 years at current staffing levels.
Policy Shifts and Executive Engagement Challenges
This technical crisis is unfolding alongside the most consequential stretch of safety policy in a generation. In April 2025, President Donald Trump signed an executive order which fundamentally shifted the focus to English proficiency and non-domiciled CDL irregularities to prevent catastrophic failures caused by “chameleon carriers.”
A recent fleet management study by J.J. Keller also shows that visible executive commitment to fleet safety culture has declined over the past two years.
The Full Report Includes Deeper Dives Into:
- The Maintenance Feedback Loop: The economics of deferred maintenance during freight recessions and how that risk manifests as utilization rises.
- Regulatory Compliance Shocks: Deeper analysis of the 2025 Executive Order’s impact on carrier operating authority and driver credentials.
- C-Suite Safety Visibility Gap: Why executive engagement is the thread separating fleets that adapt from those that fall behind.
- Actionable Safety Forecasting: Using SONAR’s OTRI, OTVI, and ELP Enforcement Index to anticipate market-wide safety risks.
