CVSA
NOTE: All inspections are to be identified as a Level IV inspection.

NOTE: The statistics will require a count of automatic slack adjuster vs. manual slack adjuster brakes and their respective adjustment (or out of adjustment). Jurisdictions will need to capture this information on their CVSA inspection sheets or on some other form in order to compile the statistics. If the jurisdiction doesn’t normally capture this information on their inspection sheet, officers will need to know ahead of time that they are required to record this somewhere on the sheet.
