to 49 USC 31144. Readers should not draw conclusions about a carrier's overall safety
condition simply based on the data displayed in this system. Unless a motor carrier
in the SMS has received an UNSATISFACTORY safety rating pursuant to 49 CFR Part
385, or has otherwise been ordered to discontinue operations by the FMCSA, it is
