Motor carrier data used to calculate SMS scores, such as Vehicle Miles Travelled and Power Unit data needs to be updated.


If your VMT data is 2009 or older, it will not be used in your calculations when the January Safety Measurement System (SMS) snapshot is posted at the beginning of February. The Motor Carrier Registration form, known as the MCS-150, is used to calculate your Unsafe Driving and Crash Indicator Behavior Analysis and Safety Improvement Category (BASIC) percentiles.

FMCSA urges carriers to update MCS-150 forms with 2010 VMT/PU information now or shortly after January 1, 2012 with 2011 data to ensure FMCSA is using the most accurate data available to calculate percentiles.

To update your MCS-150 information, visit

Under the "Existing Registration Updates" section, choose the first option - "I need to update my USDOT number registration information or file my biennial update."

PLEASE NOTE: The SMS website is updated monthly, so your MCS-150 changes will not be reflected on that site until the next monthly update. You can find the schedule of SMS updates at http://ai.fmcsa.dot.gov/SMS/InfoCenter/#question5

MCS-150 updates show up faster on SAFER and the FMCSA Portal websites.
