Crossing State Lines as a Private Carrier hauling your own products: If you cross state lines as a Private Carrier hauling your own products, you will need a USDOT number and will be subject to the Unified Carrier Registration (UCR) process. But you will not need to register for ICC Authority, MC Authority, DOT Authority or Trucking Authority (they all mean the same thing). If the vehicle crossing state lines has a Gross Weight of 26,000-lbs or less and has 2 axles, you will not be required to register for an IRP license plate, nor for IFTA fuel tax. If the truck crossing state lines has 3 axles or more with a Gross Weight of 10,001-lbs or higher, or is pulling a trailer, you will be required to register for an IRP license plate and for the IFTA fuel tax with the state and for the Unified Carrier Registration (UCR) process. If the truck or truck and trailer combination / semi-tractor and trailer weigh 26,001-lbs or more crossing state lines, you will need to register with the state of Kentucky for both an IRP License plate and for IFTA fuel tax and for the Unified Carrier Registration (UCR) process. If you are crossing state lines as a Private carrier in a vehicle with a Gross Vehicle Weight Rating of 10,001-lbs or greater, or a vehicle pulling a trailer where the Gross Combined Vehicle Weight Ratings are 10,001-lbs or greater, you will be subject to a New Carrier Entrant Safety Audit. If you are both crossing state lines with loads and picking up and delivering loads inside Kentucky without crossing state lines with these loads, you may need to register for a Kentucky DOT Number (also known as Kentucky DOT, KY DOT, and DOT Kentucky )
