The ONLY REASON for seatbelts is for a “Slow Moving Vehicle Tag”. I do know that the sunshade I have on mine is just that ! I’m not a fan of being “interviewed” by the Police. Also on the roads maintained by the US Forest service require all vehicles be street legal and this would finish mine out per the requirements. I have headlights, front turn signals, taillights with turn and stop signals, a tag mount with lamp for a European Gator I found and the “Orange Triangle”. As far as a windshield it says “appropriate eye protection” can substitute for it. No helmet required for this type of vehicle.
