Depends, because what if the bus driver looked at the road then got distracted, if he remembered what was in front of him then he would stop normally or a little over the street cross walk. (Pretending he is the only one on the road.) But if he wasn't distracted then he would stop before the line. So therefore time would be 4 seconds over the line and no overtime for the second part :p
