Left Turn From Bike Lane
Bicyclists must make left turns from within the bike lane.
Used at intersections with a left-side bike lane to direct cyclists to complete left turns from the bike lane rather than merging into the adjacent travel lane. It also alerts motorists to expect bicycles turning left from that position.
