FMCSA adds violation to the SMS

The Federal Motor Carrier Safety Administration (FMCSA) is committed to continually updating the Safety Measurement System (SMS) to align with its regulations and IT systems to effectively identify large truck and bus companies with the highest safety risk and prioritize them for an intervention.

As part of this effort, FMCSA added a brakes out-of-service (OOS) violation, also known as cite 396.3A1BOS, to the SMS. The brakes OOS violation differs from other violations in the SMS. The brakes OOS violation relates directly to underlying brake violations that are already used in the SMS. It signifies an OOS condition based on the underlying violations noted under other cites. When these underlying brake violations indicate that 20% or more of the total brakes are defective, 396.3A1BOS is cited and recorded as an OOS violation. The brakes OOS violation provides carriers and Safety Investigators with a clearer picture of the brake issues that lead to an OOS condition.

The brakes OOS violation took effect in the SMS as of April 1, 2017 and has not been implemented retroactively. Violations cited before April 1 will not be used. Impacted carriers will see this change reflected in their Vehicle Maintenance Behavior Analysis and Safety Improvement Category (BASIC) with the early May release.
