Bicycles are Vehicles

Bicycles are treated as vehicles on public roads in most, if not all, states. Cyclists have rights and responsibilities under the state's vehicle codes. In my state, California, the code can be found on the DMV web site.

"Cyclists have the same right to fair and equitable treatment by the government as other road users. The basis for these rights is expressed through the six Es approach that the League supports: Equality, Engineering, Enforcement, Education, Encouragement and Evaluation. "
