In Florida, the operation of a golf cart upon public roads is determined by the Department of Transportation or a local government. If the local government's ordinances are more restrictive than than those enacted by the state, the more restrictive ordinances are legal.
All provisions in state law that allow this stipulates that appropriate signage must be posted. Examples include signage allowing the carts on certain roadways or to cross certain roadways and other traffic signs.
So, if carts are being operated in appropriate areas, the signage would determine who has the right-of-way and any other appropriate laws. That is how I read the law.
