Miami Bike Scene reports that bicyclists are being written up by Miami police for riding on the street in the center of a lane when there's not room for a car to pass safely. Such tickets reflect a common misunderstanding of Florida law. You'll often hear people say we must ride as far right as possible, but that's not necessarily safe and it's not what Florida requires. See Florida Statutes on roadway position.
