PSA: the way to communicate with any roadside animal is to lay on the horn. They rarely experience horn-honking, and it often shocks them right out of whatever mental rut led them to run onto the road in the first place. While car lights have a dazzling effect, car horns are scary to animals.
Yeah, the horn usually gets to them, when you can see them up ahead, but one should always brake first. I used to hear 'Never swerve, use the brake instead!', and I couldn't imagine anyone with any driving experience thinking that swerving was a good idea in the first place. I never had a serious collision with a deer that was 'caught in the lights', standing on the road. Always able to slow down enough to avoid or slow bump. It's the interceptor deer on a full run that did the most damage, which happens more often than one might think.
