How to Use a Bike Box (educational video)
How to Use When Biking: When the light is red, use the bike lane to proceed to the front of the intersection and move into the bike box. Stop before the crosswalk and position yourself directly in front of waiting automobiles. When the light turns green, move through the intersection ahead of traffic. Use hand signals to tell drivers which way you’re turning, and move into the bike lane or to the right side of the street once you have passed through the intersection.
The bike box should only be used when the light is yellow or red. If you approach the intersection when the light is green, use the bike lane to approach the intersection and proceed normally.
How to Use When Driving: If you approach the intersection and the light is yellow or red, stop at the white stop line behind the green bike box. Keep the bike box clear to allow cyclists to use it. If people on bikes are in front of you in the bike box, allow them to travel first through the intersection.
