I want to buy a 4 wheeler for the express purpose of driving it around town/roads to save gas for my car. I can't seem to find any RCW's regarding 4wheeler usage on public highways, (snow mobile is prohibited unless the road is closed) (RCW 46.10.110). But I can't find anything about 4wheelers/quads. Dirt bikes are legal on the roads so long as you have a plate, what about 4 wheelers? The reason I'm asking is because I'm contemplating buying one for local transits, (long transits during summer), and I want to know if I can drive one on the public highway?
