Ive got a DOT question. How many of you actually have USDOT numbers? I know that anything over 10000lbs GVCW requires a USDOT number if its used for interstate commerce. How many of you actually mess with this? Im not trying to get over but I see lots of company vehicles around here that are over 10000 GCWR that dont display numbers. Its not hard to go over GCWR, thats basically a pickup pulling a 7000lbs trailer. Am I missing something or do I not understand exactly what "interstate commerce" is? Im starting a very part time landscaping bus. with no employees and just one truck, an F350 dually w/8' dumpbed (and a trailer). I travel between states with the truck, for the landscaping, but mostly commuting for my full time job. I would really rather not worry with the DOT if I can avoid it.
