  1. Will all motor carriers with safety alerts receive a warning letter before they hear anything else from the Federal Motor Carrier Safety Administration (FMCSA)? Answer

    Not necessarily. Motor carriers will enter the interventions process based on the nature and severity of their safety problems. If a carrier's safety problems are serious, it may enter the process through receiving an Offsite, Onsite Focused, or Onsite Comprehensive Investigation. If a carrier's safety problems are just emerging, FMCSA will issue a warning letter. If a carrier's safety performance does not improve or worsens after it receives a warning letter, the carrier will enter the progressive process and receive an investigation. If performance improves, the carrier will no longer be identified for intervention.
