Absolutely, I have a licence plate on my DS, and ride it everywhere, day and night.
All manufacturers say the quads are not for street use, and so do the tires. But all that means is that they will not cover anything under warranty, or you can't sue them if you have an accident on a street.

 

The manufacturers also say do not do wheelies, jumps, or dangerous maneuvers on your quad too.

 

NotuRaptor, I have seen many street legal dune buggies, and have seen a Warrior for sale that was street legal, and there is a guy called myketryke up in Portland that I have talked to, he makes kits for banshee's and stuff to make them street legal, by making a 1 wheel in the back and 2 in the front. I don't remember his site but type in mike trike or mike tryke in Yahoo or something and you should find it.

 

And I am a little confused, you can ride them on a regular Highway, but not something like a freeway.

 

Man that is awesome. I only get to ride on the roads for extended distances when we get a really good snow storm. A set of Holeshots would wear out in no time on pavement.

Well I guess urban legend is really true sometimes. More power to those of you in a friendly state. Maryland restricts everything.
