At a flashing red signal with no stop line, where does MUTCD-style stopping guidance tell you to stop before proceeding under stop-sign rules?

1. Before entering the near-side crosswalk, or if there is no crosswalk, at the nearest point with a view of approaching traffic
2. Halfway through the intersection
3. Wherever your front bumper is when you first see the light
4. Only after crossing all lanes of traffic
