The Federal Motor Carrier Safety Administration (FMCSA) has announced fees for the 2020 Unified Carrier Registration Plan (UCR): https://www.fmcsa.dot.gov/safety/fees-unified-carrier-registration-plan-and-agreement.
UCR fees for the 2020 registration period can only be accepted after the ruling is published in the Federal Register. This should take place within the next few days.
The UCR National Registration System (www.ucr.gov) will be ready to handle registrations when the final rulemaking is published. If you are a Maine carrier, you may also use the following link to pay online: https://apps1.web.maine.gov/cgi-bin/online/ucr/
State enforcement of the UCR registration requirements commonly begins January 1. But since the opening of the 2020 registration period was delayed several months, UCR is requesting states delay enforcement until May 1, 2020.
MMTA will make another announcement when the above sites are ready for the 2020 registrations.
