Safety Measurement System
['Compliance, Safety, Accountability CSA']

- SMS is used to judge carrier and driver performance.
- It includes two separate measurement systems.
The Compliance, Safety, Accountability (CSA) program relies on the Safety Measurement System (SMS) to judge carrier and driver performance. The SMS is a tool for assessing (measuring) the on-road safety performance of carriers and drivers to:
- Determine where specific safety problems exist;
- Identify candidates for interventions, in which the Federal Motor Carrier Safety Administration (FMCSA) or state enforcement personnel contact a carrier or driver and attempt to correct unsafe behaviors; and
- Monitor whether safety problems are improving or getting worse.
The SMS includes two separate measurement systems:
- The Carrier Safety Measurement System (CSMS), and
- The Driver Safety Measurement System (DSMS).
