October through December is the time for deer to migrate and, well, meet. You don't want to meet them with your car so this is the time for especially attentive driving.
Pennsylvania is the number one state in the nation for deer-car collisions. New York, however, is not even in the top ten. Maybe the deer are smarter here, which we wouldn't doubt, but also wouldn't count on.
Triple A says there is not much you can do except to be keenly aware of their roadside presence. Deer are most ambulatory around dawn and dusk.
Swerving to avoid one is not a good idea, particularly on a wet or, especially, snowy road, as you might lose control of your car.
So maybe simply slow down, which is not bad advice, anyway.
