Use the box left turn if you can’t merge left before you reach the intersection. Here’s how:

1. Stay in the right lane and ride across the intersection on the left side of (not in) the crosswalk.
2. Just be-fore the opposite corner, check whether there’s room for you in the traffic lane to the right of the crosswalk, behind the stop line. If there is, go there and align your-self with traffic.
3. If there’s no room behind the stop line, stop on the intersection side of the crosswalk and align yourself with traffic.
4. When the traffic light changes, move with traffic.
