Did You Know…As a motor carrier, recent Vehicle Miles Travelled (VMT) and Power
Unit (PU) data from your Motor Carrier Registration form, known as the MCS-150,
are required and must be up to date to properly assess your level of exposure in
the Unsafe Driving and Crash Indicator Behavior Analysis and Safety Improvement
Categories (BASICs) in FMCSA’s Safety Measurement System (SMS).

If your VMT data in FMCSA’s database is from 2010 or older, it will not be used
in your calculations when the January SMS snapshot is posted at the beginning of
February. Instead, the level of exposure will default to average PUs over the previous
18 months which can impact your percentiles in the Unsafe Driving and Crash Indicator
BASICs. View the SMS Methodology for addition details on BASIC percentile calculations.

Update your MCS-150 now with 2011 VMT/PU information or shortly after January 1, 2013 with your 2012 data to ensure that FMCSA is using the most accurate data available to calculate your percentiles.

Visit to
update your MCS-150 information. 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 MCS-150 updates show up faster on SAFER and the FMCSA Portal websites.
