This is a video walk through the Vigillo CSA Red Flag Scorecard for Motor Carriers. What are Red Flag Violations? According to the Federal Motor Carrier Safety Administration: When investigating a motor carrier, a Safety Investigator (SI) looks at driver history for egregious violations of the Federal Motor Carrier Safety Regulations (FMCSRs). These violations are referred to as Red Flag Violations and are always investigated as part of a carrier investigation. The Safety Investigator conducting the investigation looks to see if the violation has been corrected. At present, the FMCSA lists 12 red flag violations.
