1. Any person operating a bicycle upon a roadway at a speed less than the normal speed of traffic moving in the same direction shall ride as close as practicable to the right-hand curb or edge of the roadway except under any of the following situations:
A. When overtaking and passing another bicycle vehicle proceeding in the same direction.
B. When preparing for a left turn at an intersection or into a private road or driveway.

When reasonably necessary to avoid conditions, including (but not limited to) fixed or moving objects, vehicles, bicycles, pedestrians, animals, surface hazards, or substandard width lanes, which make it unsafe to continue along the right-hand curb or edge.

2. Any person operating a bicycle upon a roadway which carries traffic in one direction only and has two or more marked traffic lanes, may ride as near the left-hand curb or edge of such roadway as practicable.
3. When so riding upon any multi-use trail with other cyclists, there shall not be more than two abreast.
4. This section does not apply to the use of a bicycle in a parade or special event authorized by the City.
