Possible deactivation of your DOT number or an out-of-service order.

I Have Just Recently Opened My Business. Do I Need To File?
This is one of the most frequently asked questions. The answer is yes, one must file a Biennial Update on a specific month and year combination regardless of when the DOT numbered was opened.
Biennial Update filings must be completed every 24 months. If you miss your initial filing deadline, your next scheduled update will have been more than 24 months from the date you had established your DOT number. As such, if you have recently opened your business you may have to file the initial Biennial Update sooner than two years. For more information please reference regulation FMCSR 390.201T.
