About Violation Codes

Each violation found during a roadside inspection is assigned a code from the Federal Motor Carrier Safety Regulations (49 CFR Parts 350-399) or Hazardous Materials Regulations (49 CFR Parts 171-180). These codes map to one of seven BASIC categories used in the FMCSA Safety Measurement System (SMS).

Violations flagged as Out-of-Service (OOS) indicate conditions severe enough to remove a vehicle or driver from service until corrected. OOS violations carry more weight in SMS percentile calculations.

Carriers and drivers who believe a violation was recorded in error can file a Request for Data Review (DataQs) through the FMCSA DataQs system.
