CVSA truck inspection results

On May 4-6, 2021—as part of the Commercial Vehicle Safety Alliance’s (CVSA) International Roadcheck—40,000+ truck inspections were conducted, removing 6,710 commercial vehicles and 2,080 drivers from roads across the US and Canada.

The International Roadcheck is conducted annually and is meant to remove unsafe commercial motor vehicles (CMV) and drivers from roads. During this 72-hour inspection, 16.5% of vehicles and 5.3% of drivers were placed out of service. In comparison, last year’s Roadcheck in late September 2020 had a vehicle out-of-service rate of 22.2% and a driver out-of-service rate of 5.3%.

The basis for violations comes from the CVSA North American Standard Out-of-Service Criteria.

What are the levels for CVSA Truck Inspections?

There are eight different levels of inspection that the CVSA follows, however the truck inspections in this roadcheck were only subjected to the North American Standard (NAS) Level I, II, and III Inspections.

  • NAS Level I Inspection—includes a 37-step procedure examining the driver operating requirements and vehicle mechanical fitness.
  • NAS Level II Inspection—includes anything that can be inspected without getting under the CMV.
  • NAS Level III Inspection—includes a review of driver requirements, such as the license, cargo and vehicle documentation, record of duty status, seat belt usage, etc.

There were over 23,135 Level I Inspections conducted, removing 5,048 vehicles (21.8%) and 1,200 (5.2%) drivers from roadways.
