  1. How can a carrier allow multiple employees to see its non-public data without giving them the password to change the company's MCS-150 data? Answer

    Those motor carriers that want multiple employees to access their Safety Measurement System (SMS) data can do so using a Federal Motor Carrier Safety Administration (FMCSA) Portal account. Motor carrier Portal accounts contain a link to the SMS data. To set up an FMCSA Portal account, do the following:

    • Go to the FMCSA Portal and follow the instructions to request an FMCSA Portal account.
    • The first user generates an account using the company's U.S. DOT PIN and designates himself or herself as the Portal administrator for that company.
    • Additional employees can then set up Portal accounts.
    • The company Portal administrator (from Step 2) can approve anyone from the company requesting an account.
    • All Portal users the administrator has approved will have access to the company's SMS data, but only the administrator can update the MCS-150 registration data.

    For additional assistance with FMCSA Portal accounts, please call the Help Desk at 800-832-5660.
