RE: Scales??? = COMMERCIAL VEHICLES
Worded precisely. Size doesn't matter in this situation (pun).
Big motor homes 50 feet long can sail on by, but if you are driving a little Nissan short bed pickup truck with a topper that is carrying "hazmat", that is offically a commercial vehicle, must have a DOT#, and the driver must have a CDL with hazmat endorsment, or else the penalty and fines start a'coming fast and furious.
An unmarked little pickup might make it pass the scale house, but if it was placarded like it was supposed to, and had a commercial name with a DOT number on the doors, and didn't come in - well, we all know the resulting ending scenario on that one.
I can bring that one down even one notch lower. Try a litter subcompact car making a courier delivery of medical hazmat materials; such as radioisotopes or lab specimens. Thats a DOT certified commercial vehicle requiring placarding - and from my point of view, correct me if I am wrong, goes right into that scale house as well.
Each state is different, and runs by their own set of rules. Staying down here in FLorida for the past 10 years, I can only rely on FLorida law. Each scale house is operated by individuals who all have their own opinion of (themselves) and how they should operate their little empire. I call it "roadside justice".
On the side of the road, he who has the gun wins, might makes right.
Only after the fact, in a court of law, can certain travesties (transvestites?)of justice be amended.
