The North American Standard Out-of-Service Criteria for commercial motor vehicles and their drivers is developed and maintained by the Commercial Vehicle Safety Alliance (CVSA), which represents the enforcement community. Each year, CVSA committees consider and recommend modifications to the Out-of-Service Criteria, which are accepted or rejected by a vote of the CVSA member jurisdictions. The Out-of-Service Criteria are not part of the U.S. DOT regulations.
In years past, the OOS Criteria was developed and managed by the former Bureau of Motor Carrier Safety, which was a part of the former Interstate Commerce Commission.
