The Commercial Vehicle Safety Alliance (CVSA) confirmed that 10,350 commercial vehicles and 3,184 drivers were placed out of service during the 2026 International Roadcheck campaign. This three-day enforcement sweep, conducted from May 12 to 14 across the United States, Canada, and Mexico, resulted in 54,575 total inspections. The figures mark a slight increase in vehicle out-of-service orders compared to the 2025 campaign, which saw 10,148 trucks immobilized.

For fleet managers and independent operators, these numbers highlight persistent compliance gaps that threaten revenue and safety records. The data underscores that regulatory scrutiny remains intense, particularly regarding mechanical integrity and driver qualification documentation. Failure to address these issues can lead to costly downtime and potential penalties from the FMCSA.

What This Means for Truck Drivers

Brake defects continue to be the primary reason for vehicle immobilization, with 3,379 violations specifically cited for brake systems and another 2,072 for brakes with over 20% wear. Together, these issues accounted for nearly 40% of all vehicle out-of-service orders. On the driver side, missing medical examiner certificates were the top cause for disabling drivers, representing 27% of all driver violations. Every single one of those medical certificate violations occurred in the United States. Other significant driver citations included hours-of-service violations, operating without a valid CDL, and issues with English language proficiency. Electronic logging device tampering also resulted in 146 out-of-service orders, indicating that digital compliance is under close watch.

Key Takeaways

• Inspect brake systems thoroughly before every trip, as brake defects caused the highest number of vehicle out-of-service orders in 2026.
• Verify that your medical examiner’s certificate is valid and physically accessible, as missing documentation was the leading cause for driver out-of-service violations.
• Review electronic logging device usage to ensure no tampering or falsification occurs, as this remains a specific focus area for inspectors.
• Cargo securement was a designated emphasis area, with 1,724 violations serious enough to pull trucks from service.
