The database is updated every business day between 11 AM and 1 PM. FMCSA will release new authorities with dates going back 2-4 business days, so they may not show correctly when they release them and that will reflect on this list as well. This list reflects their newly granted MC authorities and it may not co-relate with other databases from FMCSA. They update each database using different parameters.
