OK, today I am driving down the road in a regular one ton pickup (GMC 3500 single rear wheels) pulling my JD4720 tractor on a 20 flatbed. I get pulled over by the State Police and get a warning ticket for not having my "DOT Registration Numbers" on the side of the truck. I was told that the US Dept. of Trans via Homeland Security now mandate any commercial vehicle with a combination weight over 10,000lbs must have their DOT number on the side of the truck. Now granted it cost nothing for the number and can be done online. My question is; has anyone else run into this situation? I went ahead and had the number added today below the new logo. What a PIA.
