So I've searched around a little... But I still have questions.. It seems if you have a tractor atv or golf cart and put the red (slow moving vehicle) triangle on it, it can be on the road legally... 1.If you have the red triangle on the back of the mini bike can it legally be driven on the road? 2. What if you bought a motorcycle (rolling chassis) and put an engine in it and it didn't do over 25mph can you still use the red triangle or does it need to be registered because it has a vin #?
