U.S. motorists warned of increased deer collision risks during mating season

Authorities across several U.S. states are warning motorists of increased deer-related collision risks due to the annual mating season, known as the fall rut. This period typically spans from mid-October through December, as bucks travel more extensively to find mates.

In New Jersey, the Department of Environmental Protection noted that the risk is heightened during dawn and dusk, and is expected to intensify following the end of daylight saving time on November 1. Delaware officials reported that between 2021 and 2025, the state recorded 8,401 deer-related crashes resulting in 312 injuries. Nationally, data from State Farm indicates that drivers face a 1 in 145 chance of colliding with an animal, with deer being the most frequent wildlife involved in such claims.

Safety officials advise drivers not to swerve to avoid a deer, as veering off the road increases the risk of hitting other vehicles, trees, or utility poles. Instead, motorists are urged to brake and stay in their lane. In the event of a collision, drivers should stop, move the vehicle off the road if possible, and contact the police without approaching the animal.
