New entrant registration
New entrant registration is the registration (US DOT number) granted a new entrant before it can begin interstate operations in an 18-month monitoring period. A safety audit must be performed on a new entrant's operations within 12 months after receipt of its US DOT number for motor carriers of property and 120 days for motor carriers of passengers, and it must be found to have adequate basic safety management controls to continue operating in interstate commerce at the end of the 18-month period.
