Bicyclists turning left from bicycle lanes on the right of
multi-lane roadways can face difficulty from high volumes of fast moving
traffic. Instead of changing lanes multiple times to access a turn lane, a
two-stage turn queue box allows bicyclists to get through the intersection in two
stages without merging into traffic.
Two-stage turn queue boxes are optional. A sign ahead of the
intersection informs the left-turning bicyclist to choose between merging into
traffic and staying in the bike lane. At the intersection, another sign directs
left-turning bicyclists in the bike lane to the turn box. There are two simple
steps to use a turn box:
- Enter the intersection on a green light and wait
in the turn box. Orient your bicycle to the left your new direction.
- Wait for the cross-traffic light to turn green then
continue through the intersection.
