(Salem, OR)  --  A move to allow motorcyclists to travel between cars is advancing in the Oregon Legislature.  The Senate has approved a bill allowing motorcycles to pass between cars or trucks during highway traffic jams.  Supporters of the measure say if motorcyclists are allowed able to move between cars during traffic tie-ups, it will reduce congestion and help keep them out of harm's way without having to break the law.  The bill now moves on to the House.
