Who knows if he would've made it home (Lucky)? Who knows what would've happened later down the highway if the truck just let him pass? Driving drunk you lose all judgment, so realizing you drive 2 tons of metal goes out the window, so in a way since everyone walked away from this is a better result for that matter, though probably not a pleasant experience for anyone.
And not that the driver of the pickup knew this, but no license and drunk...more than likely means his paperwork wasn't up to snuff on insurance either, good luck trying to get money out of him. You're on the bill financially now with your own insurance for uninsured motorist which still leaves you paying out of pocket. Would I just move out of the way and hopefully save myself the $1000+ to make myself whole again with another vehicle? You bet your ass I would.
