Long distance dolly towing

years ago i was using a dolly to bring a car back to jersey from rochester ny. drove the entire way with no issue. went to get onto the nj tp and they said no dollies allowed. so i got off and took a different rd home..

a few months ago a friend has an a rv and was getting a dolly so we looked up the laws here. you can have a dolly but it has to be starpped at the tires a also must be chained along with lights on it. most i've seen don't chain the car down. so after some research he found a dolly with a chain. we printed the page out with the law so if he ever gets stopped he should be ok,
