VIDEO: Truck plummets 70 feet over highway

I apologize in advance because this is one of those videos that you're going to re-imagine over and over again for the rest of your life when you're on a highway ramp, especially if snow is involved.

Someone coming around on the ramp appears to hit a snowbank, which then acts as a ramp and throws the truck over the side, and down 70 feet... miraculously, the driver is fine.
