What is MCS-150?
The MCS-150 is the FMCSA Motor Carrier Identification Report, the form a carrier uses to get a USDOT number and must update at least every 24 months.
It reports the company's address, operation type, power units and drivers. FMCSA can deactivate a USDOT number that is not updated on time.
The update rule is 49 CFR 390.19T.
