Frequently Asked Questions

The Frequently Asked Questions (FAQs) are questions and answers about Compliance, Safety, Accountability (CSA) that the Federal Motor Carrier Safety Administration (FMCSA) compiled to assist the public. As questions come in through the website, FMCSA adds them to the database along with their answers. If you do not see your question or topic addressed, please contact us by submitting a feedback form. We will respond to you directly and consider your question for inclusion in the FAQs.

The FAQ area has recently been enhanced. Users can now search FAQs by stakeholder group, topics (displayed on the left side of the page), or by entering a keyword below. Choosing “Show All” will display the entire collection of FAQs.

  1. What is the revised terminology used in the Safety Measurement System? Answer

    The Federal Motor Carrier Safety Administration (FMCSA) gave motor carriers a preview of the revised terminology as well as the crash breakout for eight months. FMCSA encouraged feedback on the terms before they were released publicly in December. Additionally, the crashes category is broken out from the previous "crashes with fatalities and injuries" into two separate categories: “crashes with fatalities” and “crashes with injuries.”  The table below outlines the terms that are used for each Behavior Analysis and Safety Improvement Category (BASIC).
