Law enforcement and the DOT will use a reference from the CVSA for Out-of-Service criteria. It's more a compilation of WHAT is being referenced. It directly references the FMCSR that is being looked at.
Here is a place to get a 2016 version of the OOS criteria.
The CVSA most current copy is available here if you care to get the latest and greatest.
