Towing Issues: Towing a double, tow dolly, legal answer

Question
Can you tow a car on a tow dolly that has a utility trailer hooked to the vehicle being towed? Hagerstown, Maryland

Answer
While this question is mostly out of my area of expertise, I will try to point you in a direction and offer an answer...

If I understand your question you want or need to tow a vehicle on a tow dolly with a trailer behind the vehicle..

Now if you look at this closely you will find that that that would be considered 4 units going down the road.  

While you would think it could be done, even a  truck driver would have laws regarding this issue and have to have a special endorsement on his drivers license to haul "triples"

Now the link below says it is legal but again most laws are also interputed by the officer who stops you and writes the tickets.
Best answer I can give is to check with the state police and ask them as they will provide you a much more "correct and legal" answer than I can provide you ...

Hope this helps but again it's not my real area of expertise.
