  1. Will the severity weights in the Safety Measurement System (SMS) change and can stakeholders comment on them? Answer

    The Federal Motor Carrier Safety Administration (FMCSA) invites all stakeholders to submit comments on the severity weights to the FMCSA Compliance, Safety, Accountability Docket.

Comments submitted to date have been reviewed and, where possible, suggested changes were tested for their impact on the SMS output.
