I took the mtb out for a short road ride yesterday, only 8.5 miles. While riding a car passed me and the oh so well informed driver shouted "get on the sidewalk". Do you guys that ride the roads get this kind of crap a lot?
The person who yelled at you needs to go back and retake the Florida Driver License exam. Florida is a 'Share the Road" State, which means that bicycles have the same right to be on the road as cars do.
That means of course that when we are riding on the road that we are supposed to follow all of the same traffic rules that cars do. For example, stop at stop signs and traffic signals.
Driver's are required to maintain a minimum distance of 3 feet from you as they pass.
Unless there is a specific bike lane, then you are allowed to be on the right side of the lane of traffic. Also, unless it is specified to be a bike path, Sidewalks are not for bicycles.
