While stopped behind another vehicle at a signal on a hill, how much space should you leave in front of you?

Pick an answer

1. Enough space to see the other vehicle's rear tires touch the road, in case it rolls back or you need to move around it
2. None, since staying close prevents other vehicles from cutting in
3. Enough room to see the rear tires of the vehicle ahead touch the pavement, though that's not how front actually works
4. Space in front only matters when the vehicle ahead is a motorcycle
