Safety Audit

By Korey Sharp-Paar · Reviewed by the Fast Trucking Compliance team

Definition

A safety audit is the on-site review FMCSA or state-partner investigators conduct of a motor carrier's safety management system. Two flavors: the New Entrant Safety Audit during the first 18 months of operation under 49 CFR §385.305, and the full Compliance Review for established carriers under §385.7. Audits inspect MCS-150 currency, insurance, drug and alcohol program, driver-qualification files, hours-of-service records, vehicle maintenance, and accident register. Failing the new-entrant audit can extend the new-entrant period or revoke authority; failing a compliance review can result in a Conditional or Unsatisfactory rating. Audits are scheduled by mail with a window for document preparation.
