Got pulled over at a weigh station by Pa.DOT.They are enforcing the combination weight licence requirments.They said that's it's be in the news papers and on the radio for the last 4 days,(never heard of it)If your combination weight exceeds the gross weight of your truck(regestered)then you must retitle and register your tow vehicle for your combination gross weight.If your gross weight exceeds 26,000 lbs then you also meed a CDL licence,if your trailer exceeds 10,000 lbs,you need a CDL licence.At any rate 90% of the truck/trailer combos are illegal and they will be enforcing the regulations.I got off easy,$1100 fine,I have a CDL,now I have to re-register my truck for the combo weight.They were nailing,horse trailers,open trailers,and box trailers.The state wants the extra revenue,now we must stop at all weigh stations,there is no more recreation/private use status unless your plated recreational or motorhome.Be aware.
