Cooperative Safety Plan (CSP)
A voluntary plan a carrier may implement with the help of SIs to address safety problems. This plan may be used alone or with a Notice of Violation (NOV), but it cannot replace a Notice of Claim (NOC).
Notice of Violation (NOV)
A formal notice that violations are severe enough to warrant formal action, but not civil penalties. To avoid further intervention from FMCSA, the carrier must take corrective action and provide evidence of it, or contest the violations.
Notice of Claim (NOC)
A formal notice that violations are severe enough to warrant assessment and civil penalties.
Operation Out of Service Order (OOSO)
An order requiring the carrier to immediately cease all motor vehicle operations.
