It was so dark that she couldn't see anything but headlights. There was no guardrail along the steep drop to the riverbank, but Megan pulled over as close to the edge as possible to allow the car to pass. It didn't pull out to pass but continued to ease up closer to the rear of her car. Then, Megan and Roberta were thrown forward as it bumped the rear of her car. Roberta screamed, and Megan yelled, "Mama, tighten your seat belt " She was trying to pull her own belt tighter when they were bumped again. She tried to speed up, but the other vehicle stayed right on her bumper. Then she tried to slow down, and it finally pulled out to pass. But when it pulled even with the left rear of Megan's car, it swerved into her car. Megan had no room to move over since she was already right on the edge of the steep embankment. She tried to speed up again, but the right front fender of the other vehicle hit her left rear side again and caused her to lose control. Megan's car fishtailed back and forth across the narrow road and then went over the steep embankment .
