Hint: Save lives on jump:
There is a house that has a dog that runs through a broken part of the fence. There is also a jump at that location. To avoid crashing when trying to make the jump, hit your brakes when you are about to pass it You should now see a care approaching. After it passes, go on the street and return to the sidewalk.
