Why is this update required?
The Federal Motor Carrier Safety Administration (FMCSA) requires all entities with a USDOT number to update their registration information every two years. This ensures that the safety data associated with your DOT number (like fleet size and mileage) is accurate.
Accurate data helps the FMCSA calculate safety scores (CSA scores). If your data is outdated, your safety metrics might be skewed, potentially leading to audits or higher insurance premiums.
Common Questions
When do I need to file an MCS-150 update?
You must file an MCS-150 update every two years (biennial update) based on the last two digits of your USDOT number. You also need to file an update whenever your company details (address, email, fleet size, etc.) change, or when you are reactivating a USDOT number.
What happens if I don't update my MCS-150?
Failure to update your MCS-150 can lead to the deactivation of your USDOT number and potential fines of up to $1,000 per day (capped at $10,000).
How do I know when my biennial update is due?
The second-to-last digit of your USDOT number determines the year (odd/even), and the last digit determines the month. For example, if your USDOT ends in 12, you file in February of even-numbered years.
