Do I have to have a DOT #?
If you qualify as a commercial motor vehicle as defined by (
49 CFR 390.5), the answer is YES. All commercial vehicles in Alabama must be marked with either an Interstate USDOT# or an Intrastate USDOT#. However, if you are an Intrastate company operating straight trucks and trucks with trailers having Gross Vehicle Weight Ratings (GVWR) or Gross Combination Weight Ratings (GCWR) of 26,000 pounds or less (other than passenger buses and hazardous material or hazardous waste haulers), you are exempt from all Federal Regulations while operating within the State of Alabama and a USDOT# is NOT required.
