It's not completey uncommon for people to hit elk on the highway in the mountains here, but it doesn't happen often. I only see a few dead road-kill elk a year. I don't think I've ever seen a road-killed moose here. Alaska's a little different story. On the Sterling Highway in Alaska, 214 moose-vehicle collisions were reported between mile 58 and mile 79 from 1980-2001. The most dangerous part of hitting a moose or elk is that they are so tall. If you are driving a little SUV or a car, they can fall onto the car and crush the people in the front. Same thing with horses.
