The LA Times story says:

Pananian was then ejected from the vehicle onto the overhang sign, while his car tumbled back down the embankment and came to a rest in the No. 3 lane, or the second lane to the right, Lynch said.

The Los Angeles Magazine story says:

Pananian was ejected from the car, and unbelievably, the 20-year-old's body ended up on the 5 freeway's Colorado Street exit sign in Glendale.

Both in the first few paragraphs of each story.
