Bicyclists who are turning right must use the right turn lane if one is available, and may use available left turn lanes. At intersections with turn lanes, turning movements should not be made from the through bike lanes. And about shared use paths - Shared use paths, sometimes called trails or bike paths, are used by pedestrians, skaters and bicyclists. Although bicyclists frequently use them as an alternative to riding on the roadway, bicyclists may still use the roadway adjacent to the path. There are numerous reasons a cyclist may not wish to ride on the path.
Roadways typically have fewer stop signs.
Higher speed cyclists may wish to avoid conflicts with pedestrians, skaters, and slower cyclists. Frequently, a cyclist's destination may be on the side of the roadway opposite the pathway and accessible only from the roadway. Not withstanding other provisions of this chapter, every driver of a vehicle shall exercise due care to avoid colliding with any pedestrian or any person propelling a human-powered vehicle and give warning when necessary and exercise proper precaution upon observing any child or any obviously confused or incapacitated person. Any person operating a vehicle upon the streets or highways within the state shall drive the same in a careful and prudent manner, having regard for the width, grade, curves, corners, traffic, and all other attendant circumstances, so as not to endanger the life, limb, or property of any person. The driver of a vehicle overtaking another vehicle proceeding in the same direction shall pass to the left thereof at a safe distance and shall not again drive to the right side of the roadway until safely clear of the overtaken vehicle.
