Many serious crashes occur when drivers swerve to avoid a deer and hit another vehicle or lose control of their car. Be attentive to deer crossing and speed limit signs. Deliberately look for deer and slow down if you see any. Deer are unpredictable, especially when faced with glaring headlights, and will not necessarily stay on the side of the road. Be careful, as they often dart into traffic.
Deer often move in groups.
If you see one, know that there are likely more in the vicinity.
