While driving his sports car negligently, Mark Mahoney crashes into a streetlight. The streetlight shoots out sparks that ignite barrels of gasoline sitting out in the open at a nearby construction site owned by Acme Construction. The percussion from the explosion causes Jim to fall off of a ladder where he was working four blocks away. Does Acme Construction have a viable negligence claim against Mark for the damage to its construction site? Does Mark have any viable defenses? Does Jim have a viable negligence claim against anyone?
