Ace got lost on his way to make a gasoline delivery at the Mayville Gas Station, and parked his gasoline truck on a residential street next to Tim's home. Ace knocked at several doors in the neighborhood until he found someone home who let him use the telephone. He called the gas station and got directions. However, while Ace was on the phone, Speedy came speeding along the street and ran into Ace's truck. Fire crews responded promptly, but Tim's house was totally destroyed by the fire. A large portion of the asphalt road was also consumed by fire or badly damaged. A city ordinance prohibited vehicles over two and one-half tons in weight from entering residential neighborhoods, and Ace had seen and disregarded the signs warning of this ordinance. Ace's truck weighed three tons when empty.
