In the early hours of December 4, 1997, 15-year-old Joshua Daniel had the clever idea of throwing baseball-sized chunks of concrete at vehicles on Interstate 5 from the top of a canal levee. He hit three cars before he tossed a 2.5-pound chunk at a big rig driven by William Collins, going through the windshield, hitting Collins in the forehead, and leaving him in a coma. Daniel pled guilty and was sentenced to 12 years.
Collins sued a deep pocket. Guess who?
Yes, the manufacturer of the truck...
The angle of windshields varies by type of vehicle. Heavy trucks are generally 27 degrees from vertical (63 degrees from horizontal), while passenger cars are more sloped at 55 or 65 degrees from vertical (45 or 35 degrees from horizontal).
