What's the difference between SafeStat and the new Safety Measurement System?

There are six important differences between the new Safety Measurement System (SMS) and the Agency's former measurement system, SafeStat:

• SMS is organized by seven specific behaviors (BASICs) while SafeStat is organized into four broad Safety Evaluation Areas (SEAs).
• SMS identifies safety performance problems to determine the intervention level while SafeStat identifies carriers for a compliance review.
• SMS emphasizes on-road performance using all safety-based inspection violations while SafeStat uses only out-of-service and selected moving violations.
• SMS uses risk-based violation weightings while SafeStat does not.
• SMS will eventually be used to propose adverse safety fitness determination based on a carrier's own data while SafeStat has no impact on an entity's safety fitness rating.
• SMS includes two distinct safety measurement system, carriers and drives, while SafeStat assesses only carriers.
