Kansas sidepath law?

Cyclists who ride in Kansas may know that Kansas has a "mandatory sidepath law":

8-1590(d) Wherever a usable path for bicycles has been provided adjacent to a roadway, bicycle riders shall use such path and shall not use the roadway.

Most cyclists would take this at face value. And it is bad and discriminatory law for cyclists--most paths paralleling roadways are awkward for cyclists traveling a long distane to use, and research shows that more often than not, they are less safe than cycling on the roadway.

The choice whether to use the roadway or a path should be left to the cyclist.

The Missouri Bicycle Federation went to considerable trouble a few years ago to repeal Missouri's mandatory sidepath law.

But it turns out that a Kansas Supreme Court ruling negates the Kansas mandatory sidepath language. According to a post by Kansas cyclist Dale Crawford, the reference is Schallenberger v. Rudd, 244 Kan. 230, Supreme Court of Kansas(1989):

My understanding of the decision is a bicyclist may use the road when even if a parallel sidepath exists unless the sidepath is for the "exclusive use" of bicyclists, then the bicyclist must use the roadway. I do not know of any such "exclusive" sidepaths in Kansas. All I'm aware of are "shared-use paths" or wide sidewalks available of pedestrians, roller bladders, skateboarders, runners, moms & baby strollers, dogs on leashes, etc.
