Renee Williams (plaintiff) ran out of gas five miles from home, on a route she knew included heavily trafficked interstate, with her two children in the back seat. Her car stalled in the middle of four lanes in a spot hidden from the view of approaching traffic by shadows. An eight-ton truck owned by Steves Industries, Inc. (defendant) hit her car from behind. Williams suffered injuries, and both children died. A jury found Williams negligent for failing to ensure that she had enough gas for the trip and that her negligence contributed 25 percent to the accident. Williams appealed, arguing her negligence was not a proximate cause of the accident as a matter of law.
