I went through this a few years ago when I bought a new cart which is street
Legal. University policy states that the cart must follow all state rules and regulations. Sounds easy but it's not really that simple. State regulations require headlights, tail lights, turn signals, brake lights, windshield, wipers, and seat belts. It then must be inspected at a highway patrol office just as a rebuilt/ salvage vehicle is to get a certificate to prove its roadworthy. You then take this to your county tax collector to get a tag. You will need an inspection sticker also, plus at least liability insurance just as an automobile. The low speed vehicle is then only legal on roads with a posted speed limit no higher than 30mph. I started all this and the lady at my tax collector told me to save my money until somebody forced me to register it because once it's registered, I would be subject to all laws pertaining to operation of an automobile up to and including DUI. If I was on just a golf cart, the worst I could get was public drunk and operating a illegal vehicle on a public road. I don't know if she knew what she was talking about or just didn't want to do the paperwork but I still haven't registered it and have had zero issues with campus police or game day staff. You aren't required to get a parking pass for the cart but if you park your truck and trailer on campus, you will have to get a pass for both the truck and trailer. If you park off campus you will not need a parking pass. We generally go to Starkville Station, Corkeys, and BWW with no issues from SPD and occasionally go downtown but that's usually on Friday nights. As long as nobody gets hurt, shows there ***, or uses the carts for a baby sitter, then the University is going to let the registration thing slide.
A couple of years ago, I saw a 8 yr old drive daddy's cart into the side of a quarter million dollar motorhome. That could have gotten ugly but dad was very apologetic and the MH owner was very understanding but it wasn't long after that they cracked down on underage drivers in golf carts.
