When a New York driving instructor teaches a student about pedestrian right-of-way at crosswalks, what is the rule?

1. Pedestrians have the right-of-way only at crosswalks marked with painted lines
2. Drivers must yield to pedestrians in both marked and unmarked crosswalks at intersections
3. Pedestrians must always yield to vehicles, even after entering an intersection crosswalk
4. Crosswalk right-of-way applies only during daylight rather than at night or in rain
