500
The van was packed full, and some things were attached to the luggage rack on top. My mom and dad, two sisters, and I left early Saturday morning for a one week vacation. We were going about halfway, 400 miles, the first day. My dad had made a reservation at a motel just off the highway. We were moving along on schedule, when all of a sudden there was a bang, and the car lurched. My father grasped the steering wheel tightly to keep the car under control, and then drove it onto the shoulder of the road out of the way of traffic.
