When will the Safety Measurement System (SMS) stop flagging a motor carrier?
Answer
The SMS will stop flagging motor carriers whose on-road safety performance is above
the Intervention Threshold when their Behavior Analysis and Safety Improvement Category
percentile ranks are below the Intervention Thresholds. This can happen in one of
two ways:
- Clean inspections at roadside demonstrate improved performance; and/or
- Poor inspections count less over time and eventually fall outside of the 24-month
timeframe.
Motor carriers may still be flagged for an intervention for a year if they receive
Serious Violations during an investigation or compliance review.
