On April 25, 1996, a Mack truck with a concrete mixer body, unable to stop, proceeded through an intersection at the bottom of an exit ramp. It collided with and overrode a Subaru passenger car near Plymouth Meeting, Pennsylvania.
The driver of the car was fatally injured, and the truck driver sustained minor injuries. The weather was clear and dry. No fire ensued.
