To be technically legal, I should remove my guide poles, but never have. If a Trooper really wanted to call you out on that, I'm sure that wouldn't be a cheap ticket. Not all boats are that wide, so your matching trailer might not have that problem of excess guide pole width.
I have a 2010 X-15. It does not have any such sticker. A good thing. What a trooper does not know, will not hurt him.
