VMTs are used to calculate Unsafe Driving and Crash Indicator Behavior Analysis and Safety Improvement Category (BASIC) percentiles. If the VMT data is from 2009 or later, it will not be used in the calculations when the January Safety Measurement System (SMS) snapshot is posted at the beginning of February.
Motor carriers that currently receive a VMT-based adjustment due to high truck utilization (i.e. more VMT per PU than the average) will cease receiving that adjustment if they do not update their MCS-150 form to reflect more recent data (i.e. VMT year of 2010 or 2011).
