Further, using the example of Pennsylvania above, their regs say;
"Regardless of size, the following vehicles are subject to inspection and weigh station examinations: (1) agriculture vehicles when using public highways; (2) passenger and specialty vehicles towing large trailers; (3) large recreational vehicles, and (4) trucks."
So then again by your idea only vehicles carrying passengers for hire AND towing a "large trailers" would need to be inspected?
Actually, those same regulations usually specifically exempt taxis. Pennsylvania does exactly that. If you're really interested in the facts you can go to each states commercial vehicle page and get them. You'll also find the legal definition of a passenger vehicle in those pages. Alternatively, why don't you try stopping at every weight station you come to and see how fast they tell you to go away.
Commercial vehicle weight stations are for commercial vehicles. Simple as that. Ag inspections are a whole different matter and in fact, sometimes the ag inspections and weight inspections use the same facilities. Also, some states may have special rules for RVs exceeding #26,000 which may make them subject to some of the commercial codes.
The confusion seems to stem from the fact that recreational vehicles that also appear to be commercial are sometimes stopped and the anecdotal repeating of those events morph into "RVs have to stop at weight stations". For instance, if you are hauling a trailer with "Joe's Racing Team" emblazoned all over it you will, in some instances, be considered a commercial vehicle.
Recreational vehicles are not required to stop in any commercial vehicle weight station. It's really not that hard. But, if you have any doubt, feel free to stop at any and every one and find out for yourself.
