I have had my share of deer hits, but I don't brake hard and I don't swerve to miss them. I brake, blow the horn, and keep on a straight path. Keeping the car going in a straight line is better than losing it in the ditch or rolling it over.
I have found over the years, that deer act and do strange things when in the headlights. Seems they turn to run, but then maybe dart back. I think it is because they see their shadow from the headlights and that frightens them so they don't want to run in that direction (which is straight away from the car that initially spooked them). So, I have made a habit to honk the horn in frequent short bursts and usually the deer will run away from that noise, even though they see the 'frightening' shadow (have thought about turning the headlights off too, but that doesn't make sense for driving /forums/images/graemlins/wink.gif ). The horn trick doesn't work every time, but certainly has jump-started a lot of deer to turn and run out of my path. During rut, some bucks don't give a hoot about anything else, and nothing will change their course of direction. They are charged and ......... you know. /forums/images/graemlins/blush.gif
