From wikipedia:

Aguilera Mederos's claim that his brakes failed to work could not be fully investigated due to the semi being completely destroyed in the flames.[12]The company Aguilera Mederos was working for, Castellano 03 Trucking LLC, had received 30 safety violations in the two years prior to the crash. Some of the violations included employing truck drivers unable to understand English highway signs.[12] Interstate 70 in Colorado contains many signs, only in English, between Genesee and Colorado Mills Parkway warning truckers of the steep grades, sharp curves, gear shifts, and locations of runaway truck ramps.[22]

Maybe don’t blame the young kid who was just doing his job and instead blame the company who put him into that situation?
