In accordance with FMCSA MCS-150 regulation 49 CFR Part §390.19,
every two years
all motor carriers are required to update their MCS-150 information with the FMCSA. This update must be completed in the appropriate month, every even or odd year, based on your DOT#, even if none of your information has changed, and regardless of when you last updated. Failure to complete a biennial update in your assigned month may cause deactivation of your USDOT number and could result in civil penalties of up to $1,000 per day (not to exceed $10,000).
If your DOT number ends with the number 9, your MCS-150
need to be updated. If the number before the 9 is an
odd number, you must renew by the end of September this year. If the 9 comes after an
even number, you are not due for an update until September of next year.
