Authorities said it started when a Saturn Ion was hit by another vehicle while trying to exit the highway and that the other vehicle did not stop.

According to investigators, this caused the Ion to spin out of control, which led to an 18-wheeler hitting it. The Ion then stopped in the two left lanes of the highway. Authorities said witnesses stopped to help the Ion’s driver.
