Just to throw something out here, you don't have to be over weight to be sued in a civil case. You could be empty and still be sued. They don't have to prove you were overweight all they have to prove is you bear some of the responsibility for the accident. Based on the amount of the responsibility is how much they well receive form the total amount being sued for. Somebody can sue you for virtually anything they want to. All they have to find is a lawyer that is willing to take the case.
Also in Arkansas they do not register by weight. They just charge you for the vehicle and what you put on it is up to you. I asked when I registered my truck before this one. I wanted to make sure I was licensed for what I was going to be carrying.
I have little story to tell about weigh stations, I had a Volvo semi tractor that I singled out and had it titled as Motor Home. It had a bed on it and I used it to pull my 5er. Well I was rolling up I5 empty north of Seattle and went by one of those in motion sensors that they have and it told me I had to exit. I was registered as a MH so I rolled on by. I kept looking for a chase car to pull me over but they never sent anyone after me. I think after I was going by they seen by the truck I was not commercial and just let me go.
