84% of all wildlife collisions occur in good weather on dry roads.
Wildlife is most active during dusk, dawn, and night. Deer are most frequently hit during dusk and dawn, bears and moose at night.
Headlights have an illumination range of 200 to 250 feet. To allow for sufficient brake time, reduce your speed to 45 mph at night―or even down to 30 mph when roads are icy.
Pay attention to shoulders. Even though wildlife may be off to the side as your car approaches, animals may suddenly attempt to flee by inexplicably leaping into the road. (Jackrabbits are particularly suicidal.) Slow as you approach, and don't hesitate to hit the horn.
If you drive in a state or province that employs road salt, keep in mind that wildlife embraces it as a condiment. Roads may be drier but wildlife more numerous.
