Any for-hire motor carrier operating under an FMCSA MC number - Property carriers, Household Goods carriers, and Passenger carriers - needs a BOC-3. Private carriers hauling only their own goods exclusively within one state do not. ### Do owner-operators leased to a carrier need their own BOC-3? No. If you operate under another motor carrier's MC number via a lease agreement, that carrier's BOC-3 covers your operations. You only need your own BOC-3 when you file for your own authority and run independent. ### Does a single-state intrastate carrier need a BOC-3? No. BOC-3 is specifically an FMCSA requirement for interstate operations. If you operate exclusively within one state under an intrastate certificate (issued by your state DMV / PUC), you are outside FMCSA jurisdiction and do not file. ### When do I file BOC-3 relative to getting operating authority? Best practice is to file BOC-3 within 1-2 business days after the FMCSA accepts your OP-1 application - once the MC number is assigned. The BOC-3 must be on file before the 21-day FMCSA vetting window closes for your authority to activate on time.
