CSA 2010 introduces a new Safety Measurement System (SMS) that assesses carriers' safety performance based on their violations in 7 Behavior Analysis and Safety Improvement Categories (BASICs) over the past 24 months, and identifies carriers for interventions based on their BASIC percentiles compared to similar carriers. The SMS aims to improve FMCSA's ability to identify safety problems and employ a range of interventions rather than just compliance reviews. Carriers can monitor their own data and address violations to improve their BASIC percentiles over time and avoid interventions.
