I have read these requlations at
http://www.flsenate.gov/Statutes/ind...316/ch0316.htm
and I can't find any that refer to passing slower golf carts.
Local govermental authorities can add additional restrictions to these Statues, but according to you the Sumter county sheriff and the Lady Lake Police Department have given you conflicting information. These are two different local governmental authorities, so I would think maybe they could possibly have different regulations.
Where in the statues are the passing restrictions addressed?
