In 1997, I was ticketed for being 1100lbs over-weight while traveling a Kentucky interstate highway. I was hauling a tractor on a trailer behind a 1-ton truck. The truck was well under it's tagged weight (which also includes weight scaled on trailer) I was safely under my tagged weight rating. The trailer was rated at 10,000 (Manufacturers rating) It scaled 11,100 (and change) (Truck was running 22,000lb tags)
I recieved a citation, was forced to re-position the load so as to comply with ratings on truck and trailer. (All took place at scales) I didn't challenge the citation, because, quite simply, I was in the wrong. There was no need to take anything to court. I merely paid the fine and went on, a bit wiser, and a bit poorer.
I was told at the time, that Kentucky Vehicle Enforcement Officers were looking for this particular violation, on this particular date. I drove right into a trap....
I was as nice as possible, no way the Officers were "ticked off" at me. They were just doing their jobs. I wasn't mad. (Other than at myself) They weren't mad.
Once again, I stick behind what I said earlier. Be 110% completely legal, be safe, and you don't have to worry about "what you can get away with".
