North American motorists warned of rising deer collision risks

Authorities across North America are warning motorists of an increased risk of deer-vehicle collisions due to the onset of the mating season, known as the rut. This period, typically spanning from October through December, sees heightened deer activity as animals travel greater distances and become more unpredictable, particularly at dawn and dusk.

In the United States, significant collision data has been reported across several states. New Jersey recorded 11,692 collisions in 2025, while New York saw over 32,000 accidents in 2024. In Connecticut, historical data shows that deer-related incidents have resulted in multiple fatalities and hundreds of injuries. Kansas reported over 10,000 crashes in 2025, with animal strike insurance claims rising significantly in cost. Other regions, including Delaware, Iowa, and parts of Long Island, have also issued safety advisories.

In Canada, rural drivers face similar risks, with Ontario reporting approximately 12,000 wildlife collisions annually. Safety experts and law enforcement agencies recommend that drivers reduce speed, use high-beam headlights when appropriate, and avoid sudden swerving to prevent loss of vehicle control during an encounter.
