Mark your calendars: The Commercial Vehicle Safety Alliance has scheduled its 2027 International Roadcheck for May 11–13.

The annual three-day inspection blitz brings thousands of commercial vehicle inspections to highways, weigh stations, and other inspection sites across the United States, Canada, and Mexico.

CVSA has not yet announced the vehicle and driver violations that will receive special attention during the 2027 event. Those focus areas typically are announced closer to Roadcheck.

What Happens During International Roadcheck?

During the 72-hour enforcement initiative, CVSA-certified inspectors check commercial motor vehicles and drivers for compliance with safety regulations.

Inspectors primarily conduct the North American Standard Level I Inspection, a 37-step procedure that examines both the driver's qualifications and the vehicle's mechanical condition.

On the vehicle side, inspectors check items such as brake systems, tires, lights, steering, suspension, coupling devices, and cargo securement.

Driver inspections include checking commercial driver's licenses, hours-of-service records, medical qualifications, and other required documentation. Inspectors also look for signs of impairment.

Drivers or vehicles with serious violations can be placed out of service until they correct the violations.

Trucks that pass an eligible Level I or Level V inspection without critical vehicle inspection violations may receive a CVSA decal, valid for up to three months.

What Happened During 2026 Roadcheck?

During the May 12–14, 2026, International Roadcheck, inspectors conducted 54,575 inspections of commercial vehicles and drivers across North America.

About 19% of the vehicles inspected and 5.8% of drivers were placed out of service for violations.

The 2026 event placed special emphasis on cargo securement and electronic logging device tampering and falsification.

But some of the most notable findings involved driver qualifications. Medical certification violations topped the list of driver out-of-service violations, while English-language proficiency violations emerged as a significant issue.

CVSA has conducted International Roadcheck annually since 1988, with more than 1.8 million roadside inspections over the program's history.

The organization is expected to release more details about the 2027 enforcement priorities as the event approaches.
