The Importance of Maintaining an Accurate MCS-150

Do your company’s Unsafe Driving and Crash Indicator Behavior Analysis and Safety Improvement Categories (BASICs) percentiles on the FMCSA’s Safety Measurement System (SMS) look inaccurate to you?  It could be that you are in need of updating your company’s Vehicle Miles Travelled (VMT) and Power Unit (PU) data on your Motor Carrier Registration Form (aka: MCS-150.)

Accurate VMT and PU information is vital to properly asses your level of exposure.  If your VMT data is from 2010 or older, it was not used in your calculations for the January SMS snapshot.  Instead, the level of exposure defaulted to average power units over the last 18 months.  Obviously, this could impact your percentiles in the Unsafe Driving and Crash Indicator BASICs.

To update your MCS-150 with 2012 VMT and PU information, go to:  Under the “Existing Registration Updates” section, choose the first option: “I need to update my USDOT number registration information or file my biennial update”.

You may wish to note that 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
