GREENBELT, Md. — The Commercial Vehicle Safety Alliance (CVSA) has officially released the comprehensive findings from its 39th annual International Roadcheck, casting a revealing light on the state of commercial motor vehicle safety across North America. The data, compiled from a high-intensity, three-day enforcement blitz conducted this past May, underscores both the persistent mechanical vulnerabilities and the ongoing compliance challenges present within the commercial trucking and bus industries.
While the vast majority of commercial motor vehicle (CMV) operators and carriers continue to meet rigorous safety benchmarks, the sheer volume of out-of-service violations discovered during the 72-hour event serves as a stark reminder of the critical importance of proactive maintenance, stringent administrative compliance, and unwavering adherence to hours-of-service (HOS) regulations.
Main Facts
The 39th annual International Roadcheck was a massive, coordinated continental effort involving thousands of CVSA-certified local, state, provincial, and federal inspectors stationed at weigh stations, traffic checkpoints, and mobile patrol units throughout North America.
During the three-day operational window, inspectors conducted nearly 55,000 visual and physical inspections on commercial motor vehicles, ranging from heavy-duty tractor-trailers to passenger-carrying motorcoaches. The rigorous evaluation process focused heavily on standard mechanical components—such as brake systems, lighting, tires, suspension, and steering mechanisms—alongside driver credentials, operating hours, and substance compliance.
The core takeaways from the 39th annual event include:
- Total Inspections: Approximately 55,000 commercial trucks and buses evaluated over a 72-hour period.
- Vehicle Out-of-Service (OOS) Rate: 19.0% of inspected vehicles were pulled off the road immediately due to critical safety violations.
- Driver Out-of-Service (OOS) Rate: 5.8% of inspected drivers were prohibited from operating commercial vehicles due to disqualifying infractions.
- Top Vehicle Deficiencies: Brake systems (24.3%) and tires (20.9%) remained the leading mechanical culprits.
- Top Driver Infractions: Lack of a valid medical examiner’s certificate (27.0%) and hours-of-service violations (23.4%) topped the driver OOS list.
- Special Enforcement Focus: Electronic Logging Device (ELD) tampering/falsification and proper cargo securement were spotlighted, yielding significant enforcement statistics.
Chronology of the 72-Hour Enforcement Blitz
To fully understand the magnitude of the International Roadcheck, it is essential to examine the operational timeline and the coordinated framework that makes such a massive continental sweep possible.
Pre-Event Planning and Coordination (Months Leading Up to May)
Planning for the annual International Roadcheck begins months in advance. The CVSA, in partnership with federal regulatory bodies in the United States, Canada, and Mexico, establishes the dates and central themes for the upcoming enforcement period. Law enforcement agencies at all levels undergo specialized training updates, ensuring that inspection protocols remain uniform across jurisdictions. Carriers and drivers are given advance notice through industry publications and safety campaigns, allowing fleets to conduct preemptive maintenance checks and review compliance records.
Days 1 through 3: The Operational Window (May)
The enforcement blitz itself unfolds over 72 continuous hours.
- Hour 0–24: As the event kicks off, inspection stations experience an immediate surge in volume. Specialized teams zero in on high-traffic freight corridors. Early reports on Day 1 typically highlight routine maintenance oversights, such as worn wiper blades, minor lighting failures, and tires approaching tread depth limits. However, more serious brake and suspension discrepancies quickly emerge as inspectors utilize specialized diagnostic tools and crawl beneath vehicles.
- Hour 24–48: Moving into the second 24-hour cycle, the focus shifts toward more complex administrative and technical compliance. Inspectors rigorously audit Electronic Logging Devices (ELDs) to detect manipulation, unauthorized edits, or attempts to bypass federal hours-of-service limits. Cargo securement is heavily scrutinized as long-haul trucks transit state and provincial borders, with inspectors ensuring that tie-downs, chains, and blocking devices meet North American Cargo Securement Standard requirements.
- Hour 48–72: The final stretch of the Roadcheck often reveals fatigue-related infractions as drivers push to complete routes before the conclusion of the enforcement window. Inspectors maintain high visibility until the final hour, ensuring that every vehicle cleared through the check meets the stringent safety thresholds mandated by law.
Data Compilation and Analysis (Post-Event Phase)
Following the conclusion of the 72-hour event, local and regional agencies submit their inspection data to central databases. The CVSA aggregates, cleans, and analyzes this vast dataset to identify macro-trends, emerging mechanical vulnerabilities, and shifts in driver compliance patterns. The release of these finalized findings provides the foundational metrics used by policymakers, safety advocates, and fleet managers for the remainder of the year.
Supporting Data and Breakdown
A granular examination of the data gathered during the 39th annual Roadcheck reveals specific areas where the commercial transportation industry excels, as well as critical zones requiring immediate corrective action.
Vehicle Out-of-Service Violations
Out of the tens of thousands of commercial motor vehicles inspected, nearly one in five (19.0%) was deemed unsafe to continue operating and was placed out of service until necessary repairs could be completed. The leading mechanical violations driving this statistic were:
- Brake Systems (24.3%): Brake-related infractions continued their historic reign as the number one vehicle violation. These included out-of-adjustment pushrods, cracked brake drums, leaking air chambers, and worn-out friction material. Given the immense stopping distances required for heavy commercial vehicles, compromised braking systems pose a catastrophic risk to all motorists.
- Tires (20.9%): Ranking second, tire-related deficiencies included tread depth falling below legal minimums, exposed cords, sidewall cuts, and improper inflation pressures, which can lead to dangerous blowout incidents at highway speeds.
- Cargo Securement (12.4%): Ranking fourth overall among vehicle violations, improper or inadequate cargo securement accounted for a significant share of OOS orders. Unsecured or shifting freight poses an extreme hazard, capable of causing vehicle rollovers or spilling onto active roadways, endangering trailing traffic.
Driver Out-of-Service Violations
While the vast majority of commercial drivers proved compliant, 5.8% were placed out of service for safety-critical infractions. The distribution of these violations highlights ongoing administrative and behavioral challenges within the driving workforce:
- No Medical Card (27.0%): The leading driver OOS violation involved operators failing to possess, or maintain a current, valid medical examiner’s certificate. Ensuring that drivers meet physical and mental fitness standards is a foundational element of CMV safety.
- Hours of Service (23.4%): Fatigued driving remains a pervasive industry concern. HOS violations occur when drivers exceed maximum allowable driving hours, fail to take mandatory rest breaks, or operate outside designated duty-status windows.
- Electronic Logging Device (ELD) Tampering (3.7%): While representing the seventh-leading driver OOS violation, ELD tampering, falsification, or manipulation remains a critical focus for enforcement personnel. Unscrupulous operators resort to software hacks, phantom logging, or manual overrides to conceal illegal driving hours.
Official Responses and Industry Stakeholder Perspectives
The release of the 39th annual International Roadcheck data prompted widespread commentary from regulatory leaders, safety advocates, and industry associations across North America.
Regulatory Collaboration
The International Roadcheck is a truly international endeavor, underscoring the collaborative framework established between the Federal Motor Carrier Safety Administration (FMCSA) in the United States, the Canadian Council of Motor Transport Administrators (CCMTA), Transport Canada, and Mexico’s Ministry of Infrastructure, Communications and Transportation (SICT).
In joint statements released alongside the data, representatives from these agencies emphasized that cross-border cooperation is vital for maintaining uniform safety standards. "Commercial motor vehicle safety does not stop at international or state boundaries," a senior FMCSA spokesperson noted. "Our shared commitment through the International Roadcheck program ensures that sub-standard equipment and non-compliant operators are identified and removed from our roadways, regardless of where their journey began."
CVSA Leadership Insights
CVSA President and enforcement officials highlighted the dual nature of the Roadcheck results. On one hand, officials expressed satisfaction that the vast majority of commercial vehicles and drivers pass inspection without receiving out-of-service orders, reflecting a strong baseline culture of safety among professional fleets.
On the other hand, leadership voiced persistent concern over recurring mechanical issues, particularly regarding braking systems and tires. "It is disappointing to see that basic maintenance items like brakes and tires continue to account for nearly half of all vehicle out-of-service violations," a CVSA spokesperson stated. "These are components that can—and should—be caught during routine pre-trip and post-trip inspections. Professional drivers and motor carriers have a shared responsibility to ensure their equipment is road-ready before turning the ignition key."
Motor Carrier and Driver Associations
Representing the commercial trucking industry, various carrier associations responded to the data by calling for increased investment in preventive maintenance technology and driver wellness programs. Industry representatives noted that supply chain pressures and driver shortages can sometimes create an environment where shortcuts are tempting, making structured compliance management more critical than ever.
Implications for the Future of Commercial Transportation
The findings of the 39th annual International Roadcheck carry profound implications for the future of commercial motor vehicle safety, regulatory enforcement, and fleet management practices.
The Shift Toward Advanced Digital Enforcement
The prominence of ELD tampering and data manipulation in this year’s data highlights a broader evolution in compliance monitoring. As commercial vehicles become increasingly digitized, enforcement techniques must keep pace. Inspectors are now equipped with advanced hardware and specialized training to interrogate ELD systems, detect software modifications, and identify falsified logs in real-time.
This trend signals that traditional roadside inspections are no longer limited to mechanical walk-arounds; they are increasingly sophisticated digital audits conducted on the side of the highway. Fleets that rely on outdated logging methods or attempt to subvert digital mandates face a drastically higher probability of detection and severe penalties.
Economic and Supply Chain Ramifications
While safety enforcement is designed to save lives, out-of-service orders have immediate operational and economic consequences for motor carriers. A truck sidelined for a severe brake defect or an HOS violation incurs costly repair bills, towing fees, missed delivery windows, and potential CSA (Compliance, Safety, Accountability) score degradation.
For smaller fleets and independent owner-operators, a single major OOS event can severely impact profitability. Consequently, the Roadcheck data serves as a powerful financial argument for proactive fleet maintenance. Carriers are increasingly turning to predictive maintenance software, telematics, and automated vehicle health monitoring to catch worn tires and failing brake components before they result in a costly roadside citation.
The Ongoing Battle Against Fatigue
The high ranking of hours-of-service violations and the persistent threat of driver fatigue reinforce the need for comprehensive industry reform regarding driver well-being. Regulatory bodies, shippers, and carriers are under mounting pressure to address the structural causes of driver fatigue, including lengthy loading/unloading delays at shipping facilities, rigid delivery schedules, and compensation models that do not adequately account for non-driving duty time.
Conclusion
The 39th annual CVSA International Roadcheck is far more than a statistical snapshot; it is a vital diagnostic tool for the North American transportation sector. By identifying specific areas of vulnerability—ranging from neglected brake drums and worn tire treads to administrative lapses and ELD manipulation—the data provides a clear roadmap for regulatory bodies, law enforcement agencies, and motor carriers alike.
As the industry looks ahead to future enforcement cycles, the message from safety advocates is unmistakable: continuous vigilance, rigorous preventive maintenance, and strict adherence to regulatory standards are non-negotiable prerequisites for operating on our shared continental highway system.
