Annual Probability of a Car-Deer Collision

Approximately 1.5 million vehicle-deer collisions occur in the United States each year, according to insurance industry data. This translates to about a 1 in 143 chance for any given driver in a given year. These collisions result in about 150-200 deaths, 10,000 injuries, and over $1.1 billion in vehicle damage annually.

The risk varies enormously by location and time of year. West Virginia has the highest per-capita collision rate (about 1 in 37 drivers), followed by Montana, Pennsylvania, South Dakota, and Iowa. Peak deer collision season runs from October through December, coinciding with deer mating season (the rut), when deer are more active and less cautious. About 80% of deer collisions occur on two-lane roads, and the majority happen between dusk and dawn.

Prevention strategies include being particularly vigilant during dawn, dusk, and nighttime hours in fall months, scanning the roadside for deer eye-shine, using high beams when possible, slowing down in areas with "deer crossing" signs, and being aware that if you see one deer, more are likely nearby. If a collision is imminent, experts advise braking firmly but not swerving, as swerving often leads to more severe accidents involving other vehicles or objects.
