Our small mountain valley town recently Ok'ed golf-type carts on city streets. Very nice. The electric ones are dead quiet and quite quick. Most now are licensed. Do not know if legal on the big highway. Some are very very small. Pictures on the way I hope. HB
Theyre are lots of towns here in N.H that you can drive atv/snowmobiles legally on city streets . (As long as it is registered for off road through state ) and no inspection!
Under DOT regs, anything that does not meet ALL Safety Standards is not legal to be driven on any public street, road or highway or licensed for such use or sold as being capable of such use. Lots of people do what they want to, but that's the Federal law, going back to the Nixon administration.
It looks like the government made new rules FMVSS 500 that addresses "low speed vehicles". Making some smaller golf cart type vehicles legal if they meet the new rules.
