Steps

  1. Check gross vehicle weight rating (GVWR) or gross combination weight rating (GCWR): a USDOT number is required if it is 10,001 lbs or more and the vehicle is used in interstate commerce
  2. Confirm whether operations cross state lines or otherwise meet FMCSA's definition of interstate commerce (including trips that start or end outside the state even if the truck itself stays in-state)
  3. If operating strictly intrastate, check your state's own requirements — many states listed by FMCSA (including Texas, Arizona, and California) require a USDOT number for intrastate carriers even though federal law alone would not
  4. Use FMCSA's online USDOT number wizard to get a definitive yes/no determination for your specific vehicle and route pattern
  5. If hauling in interstate commerce for-hire, apply for both a USDOT number and MC/operating authority via the FMCSA URS registration portal; intrastate-only carriers generally only need the state-required USDOT number, not MC authority
