MCS-150

Also: biennial update, biennial update form

The MCS-150 is the form a carrier files to update its information with FMCSA. Every carrier with a USDOT number must update it at least once every two years on a schedule set by the last two digits of the number, even if nothing changed. Filing the MCS-150 with FMCSA is free.
