Deer–vehicle collisions

[2] State and federal governments, insurance companies, and drivers spend an additional $3 billion in an effort to reduce and manage the increasing number of deer-vehicle collisions.

[11] West Virginia is the state with the highest risk that a motorist will hit a deer whilst driving.

According to a study done by Jennifer Raynor, a natural-resource economist at Wesleyan University, wolves in the US state of Wisconsin were responsible for a 25% reduction in deer-vehicle collisions after being reintroduced into the environment there.

The most common type of habitat fragmentation across the United States is roadways and highways in forests and other deer-inhabited areas.

[15] Roadways and highways located in sparsely-populated areas are usually built along rivers and lakes of mountains and plains.

Roadways and highways within densely populated deer habitat lead to more prevalent deer-vehicle collisions.

A contributing factor to deer-vehicle collisions is the time of day at which motorists travel through deer habitation.
