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. When does the Safety Measurement System (SMS) update? Answer

    The data in the SMS updates once a month. 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 before it is updated on the website. It states in the upper right-hand corner in the search box of the SMS homepage the date upon which the current data is based.

    However, the MCS-150 data updates happen much faster in SAFER and roadside inspections are updated faster in the Federal Motor Carrier Safety Administration’s Portal. If the MCS-150 data is up-to-date in SAFER, then it will likely be updated in SMS the next month. Here is the schedule of when SMS updates.
