I live at the foot of that highway and drive it regularly towing and not. I can say the wrecks are real. I rarely go over without seeing a truck or car fire or wreck due to weather or speed or sleep/distraction or imparement. I've personally seen a car full of people drive off a cliff up there. First snow up there last weekend was sheer ice on all lanes and littered with wrecks. Semis and cars. The personal drama stuff gets silly on hwth -but on the road? That's not funny at all. Very real. Realize it has some of the highest grades in North America. You are literally travelling at the mountain tops.
