What is a "Bike box"?

A bike box is a designated area at the head of a traffic lane designed to prevent bicycle/car collisions. This holding area allows cyclists a safe and visible way to get ahead of waiting traffic during a red light. The bike box is a green box on the road with a printed white bicycle symbol. Green bicycle lanes approach and lead from the bike box.

Why is the box green?

Green is the standard color approved by the Federal Highway Administration for bicycle lanes and boxes.

What cyclists should know

Enter the bike box as the traffic signal is yellow or red. Stop before the crosswalk and position yourself in the box according to the direction you are intending to go. Note: If the traffic signal is green, cyclists should proceed through the intersection as normal.

What motorists should know

When the traffic signal is yellow or red, motorists must stop at the white line before the green bike box. Motorists should not stop on the bike box so it remains clear for cyclists to use. Right turns on red are prohibited when bike boxes are present. When the signal turns green, motorists should allow cyclists to move through the intersection first.

Benefits of bike boxes

  • Cyclists become more visible to motorists and pedestrians.
  • As motorists are turning right, the bike box reduces the risk of "right-hook" conflicts.
  • Bike boxes allow a larger area for pedestrians to transit.
  • Reduces signal delay for cyclists.
  • Intersections are cleared more quickly because the area allows cyclists to be grouped together.
  • Encourages more cycling by establishing a safer road environment.
