Best bet is to visit the FMCSA web site and FMSCA SAFER to determine when you need what credentials FEDERALLY...Remember though, you still have to contact each state.
there are servi e provixers out tbere that claim to know all this for you...they don't.
And keep in mind, Federal regulations in this regard only apply if one crosses state lines. Within a state, state regulation apply. Many states follow the FMCSA stuff, but some really go their own way when it comes to intrastate.
