Thats right. USDOT covers all states. There is a State DOT number you can get as long as you aren't leaving the state but it still adheres to USDOT regs. I'm not planning on doing business outside the state but its possible I could go to Delaware to purchase some equipment so I got the USDOT number to cover me. Not trying to hijack the thread but since we are on the DOT topic what DOT paperwork do you guys carry with you in your truck in case you get stopped.
