Subject:  USDOT Number Required to Register Commercial Motor Vehicles

Advisory Date:  02/27/09                              Implementation Date:  Immediately                                   

Advisory Number:    MCS 09-01



                        Motor Carriers that operate commercial vehicles transporting passengers or hauling cargo in interstate commerce must be registered with the Federal Motor Carrier Safety Administration (FMCSA) and must have a USDOT Number.


                        Section 320.0715, F.S., was revised during the 2008 legislative session to require the department to withhold registrations and license plates for commercial motor vehicles that have not been issued a USDOT number.  This change only affects commercial motor vehicles operating in interstate commerce.  Vehicles operating intrastate only with a Florida straight plate will not be impacted. 


                        The attached notice will be sent to carriers currently registered under the International Registration Plan (IRP) along with renewal notices to advise them that they will be required to provide their USDOT number prior to being issued an apportioned license plate.


                        Form HSMV 85103, Welcome to the State of Florida’s International Registration Plan, has been updated to include information about obtaining USDOT numbers.  When issuing a Temporary Operational Permit, you should provide the customer with these instructions so they will be aware of the requirement to provide their USDOT number when submitting their application for an apportioned license plate.  If this number is not provided, the application will be rejected.


                        If you have any questions or need further assistance, please call the Bureau of Motor Carrier Services at (850) 617-3711.












USDOT Number Now A Required Part of the IRP Registration Process In Florida


Effective with your April 2010 IRP renewal, or April 1, 2009 new IRP accounts, providing a valid USDOT number will become a required part of the IRP registration process in Florida.


Your IRP credentials will not be issued unless you provide your valid USDOT number.


Section 316.302, Florida Statutes, requires all owners and drivers of commercial motor vehicles operating in interstate commerce in Florida to have a USDOT number in accordance with the rules and regulations contained in 49 CFR Part 390 of the federal regulations. 


A commercial vehicle is generally defined as a self propelled or towed vehicle used on the public highways that 1) has a gross vehicle weight or gross combination weight rating, or gross vehicle weight or gross combination weight of 10,001 pounds or more, whichever is greater; 2) is designed or used to transport more than 8 passengers including the driver for compensation;  3) is designed or used to transport more than 15 passengers including the driver not for compensation; or 4) is used in the transportation of hazardous materials.  For information on the requirements related to the USDOT number and how to register, contact the Federal Motor Carrier Safety Administration (FMCSA) at 800-832-5660 or online at 


The department has been collecting USDOT numbers for several years on a voluntary basis.  As a registrant under the IRP, you may have previously provided your USDOT number or the USDOT number of the motor carrier you were leased to or that was responsible for the safety requirements on your vehicles.  Prior to returning your renewal, please verify that the USDOT number on your renewal form is your USDOT number.  If you have not obtained a USDOT number, you must contact the FMCSA as noted above to get your number.  Your IRP credentials will not be issued unless you provide your valid USDOT number.


Requiring a USDOT number prior to issuing IRP registrations is the first phase in Florida’s implementation of the federal Performance and Registration Information Systems Management (PRISM) program.  Additional information on Florida’s participation and implementation in the PRISM program will be provided as we move forward in the process.
