A 19-year-old California native, Siegel was in the midst of a third lap during a simulated qualifying run when his No. 18 Dale Coyne Racing Honda snapped around and hit the outside wall on the exit of Turn 2.
After making contact with the wall, the back of the car lifted off the ground, getting almost inverted, and skated down the backstretch on its left side before coming to a stop in the middle of the track.
