  1. The Safety Measurement System (SMS) Methodology document states that a carrier can receive no more than 30 severity points in a single inspection. If a carrier has more than 30 severity points, which points are carried over to SMS? Answer

    This statement is not entirely correct. The SMS Methodology document states that the sum of all severity weights yielded by any one inspection for violations in any one Behavior Analysis and Safety Improvement Category (BASIC) is capped at a maximum of 30. The inspection cap of 30 applies to the sum of violation severity weights within a BASIC, not summed across all BASICs. This rule prevents one bad inspection from overwhelming the evaluation of a particular BASIC and allows SMS to assess a motor carrier's safety performance across several inspections.
