While it is certainly preferable for cyclists to use roadways with marked bike lanes to avoid a Chicago bike accident, bikes are permitted to ride along all City streets with the obvious exception of Lake Shore Drive and expressways.  The City of Chicago publishes a fairly easy to use bike map that can aid cyclists in planning their routes.  As Chicago cyclists become more accustomed to their routes, the existence of streets Chicago bike lanes will become easier to recall.   While marked bike lanes are preferred, bike commuters need may lawfully use streets without bike lanes.  Following a collision that caused a Chicago bike injury, the offending driver told the sufferer of the bike injury that he was not at fault because the cyclist was not on a marked bike lane.  The driver’s statement was incorrect, which he will discover when he meets the Chicago bike lawyer.
