Bike Etiquette and Common Sense
V. Our public roads are for shared use
Since the inception of the "Good Roads" campaign by the League of American Bicyclists (formerly the League of American Wheelmen) in the 1890s, public roads across the land have been for shared use.
The L.A.W.'s lobbying paved the way for cars. Today, laws are still clear that roads are for all users. On roadways, might doesn't constitute right. See California Vehicle Code
