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.

  1. How often are the Safety Measurement System (SMS) results updated? Answer

    SMS results are updated monthly. A snapshot of the data is taken on the third or last Friday of each month and then it takes approximately 10 days to process and validate the data. Once validated, the results are uploaded to the SMS Website. The table below lists a tentative schedule for future releases of SMS results:
