ATV Trailer width?

I know that in Idaho that an ATV can not have an outside tire width of more that 50 inches. Does this also pertain to a trailer being towed by the ATV . I am looking at buying a trailer, but it measures at 51 inches. Would that be legal? On approved trails?
Answer: 
No, it would not be legal.  The width restriction also pertain to anything towed behind the ATV.  Please contact the appropriate land management agency for more information on allowable uses.
