A bike box in front of the stop line is meant to give cyclists a safer start in the intersection. For you as a driver, that means your position and stopping point must be precise, especially during rush hour and in dense traffic.

What you need to know

  • The stop line applies even when you feel you could roll a little farther forward.
  • The bike box makes cyclists more visible before the light turns green.
  • Wrong positioning can block cyclists or create conflict when traffic moves off.

Typical situations

Common mistakes

  • Thinking the box only matters if cyclists are actually standing there.
  • Stopping too late because you follow the flow of the queue.
  • Overlooking that the bike box is connected to lane choice and indicator use.
