"This massive storm will be with us for the next few days," the radio announcer said. "The cold front has created dangerous driving conditions throughout the area. If you're out on the road, be careful and drive smart. If you can help it, don't go out in this storm at all," she warned. Jesper had to get home, but he wasn't too worried because he had always been a cautious driver. He told himself that he would go slowly and take his time. He didn't have to be home at a specific time, which helped. The first half of the drive went off without a hitch, no trouble at all. Although he did see one car on the side of the road, it didn't seem like they were in distress, so he kept driving along. They probably were just nervous and decided to pull over. However, Jesper wasn't nervous. He had driven in treacherous conditions before, and he knew how to handle his vehicle.

As he turned around a bend in the road, the road got quite a bit icier. He could see a small hill straight ahead. He worried for a minute since he was driving slowly and the ice on the road might prevent him from making it up the hill.
