The golf carts here you must register get tag and be at least 15 to drive insurance is not required but recommended.
stop someone driving a golf cart and ask them, or call your local police department and ask them
If it’s a town of about 500, then I would just not behave in unpredictable ways/badly while driving. Don’t drive like a moron, pull over and let cars pass, etc and it shouldn’t be a problem. Markers, by reflective tape packages sold in many stores, should be put on your cart. And one of those slow moving vehicle (orange triangle) signs is probably a very smart if not required thing to have.
CHECK YOUR LOCAL CITY ORDINANCE
The sheriffs office and ask.
