Dave age 15 is anxious to learn to drive a car. Dave does not have either his learners' permit or a driver's license. On Saturday, while his parents are on an all day shopping trip, Dave decides to practice backing his parents' other car out of the garage and into the driveway. Dave successfully backs the car onto the drive way. However, when he pulls the car back into the garage, Dave misjudges the length of the front of the car and runs over the next door neighbor's lawn mower that Dave's dad had borrowed.

Did Dave breach his general duty, special duty, both, or neither? Explain your answer.
