Turn Box

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.
