I think this was the stopping exercise. You can't really see it in the photo, but above each of the three cone-marked lanes is a stoplight. When we begin, the three stoplights are green. Then right when we're almost passing under them they turn red and we have to stop. We practiced stopping with and without engaging the ABS system. In the changing lanes exercise, the three lights would start off green, but at the last minute, two would turn red and one would stay green: we had to swerve into the green lane, which was randomly on the left or right lane so that we wouldn't try to guess. Bri tried to guess and ended up in the wrong lane a few times. One time they turned them all red to throw me off, which worked: I didn't swerve but also didn't stop right away. The point of this was to be prepared for anything. We all "killed" a few cones on these exercises.
