  1. What is included in the Carrier Registration Information? Answer

    The Carrier Registration Information contains a summary of the registration information provided by the motor carrier to the Federal Motor Carrier Administration (FMCSA). This information is current as of the Safety Measurement System (SMS) data snapshot date. If a motor carrier updates its registration information after the SMS data snapshot date, the changes will be reflected in the next monthly SMS results.

    The most up-to-date registration information for a motor carrier can be obtained from FMCSA's SAFER system at http://safer.fmcsa.dot.gov .

    The date of the last update to the registration information is also listed. Motor carriers are required to update this data at least every two years. A message is displayed if the registration data has not been updated within the two-year requirement period.

    Instructions for updating motor carrier registration information are displayed by selecting the Update Registration Information button.

    Selecting the View Carrier Registration Details button will display additional details of the motor carrier's registration information, including contact information, operation classification, and type of cargo carried.
