As questions come in through the website, FMCSA adds them to the database along with their answers.

  1. How long does a carrier remain in the Compliance, Safety, Accountability (CSA) intervention process? Answer

    Generally speaking, a motor carrier remains in the CSA intervention process until the carrier no longer has Behavior Analysis and Safety Improvement Categories (BASICs) exceeding the threshold. In the event that a carrier's BASIC percentile ranks fall below the threshold during an investigation or other intervention, the Agency will complete its work.
