Being a diesel mechanic, those who say to downshift and put in park are idiots.
A bus/truck that works with airbrakes has to be properly aired in order for the brakes to work. Going down a steep hill like that could easily expend the reserve air.
The hole I see is why doesn't that highway have a runaway truck ramp if it's such a steep grade?
