316.2065 Bicycle regulations.—
(5)(a) Any person operating a bicycle upon a roadway at less than the normal speed of traffic at the time and place and under the conditions then existing shall ride in the lane marked for bicycle use or, if no lane is marked for bicycle use, as close as practicable to the right-hand curb or edge of the roadway except under any of the following situations:
1. When overtaking and passing another bicycle or vehicle proceeding in the same direction.
2. When preparing for a left turn at an intersection or into a private road or driveway.
3. When reasonably necessary to avoid any condition or potential conflict, including, but not limited to, a fixed or moving object, parked or moving vehicle, bicycle, pedestrian, animal, surface hazard, turn lane, or substandard-width lane, which makes it unsafe to continue along the right-hand curb or edge or within a bicycle lane. For the purposes of this subsection, a “substandard-width lane” is a lane that is too narrow for a bicycle and another vehicle to travel safely side by side within the lane.
