Could go either way. It's a tough pass, and a minor mechanical error can mushroom into a crash like this.
The initial investigation revealed that the semitrailer was speeding, with smoke coming from the brakes and the driver failed to take the runaway truck ramp about 1.5 miles from the scene of the crash.
Seems like a poor choice - maybe no habla ingles? The warning signs on the pass are huge - kind of hard to miss.
Minor mechanic issues on trucks become huge issues because pakis don't maintain their rigs. Going down a steep grade with such an issue, having no experience with air brakes and gearing down, and of course the inability to read signs all makes these dumb pakis ticking time bombs on our roads. Thankfully it didn't kill innocent Americans THIS time.
