From the NYS Police:
Every October and November, Troopers handle an increased number of vehicles collisions striking deer in Troop A-Western New York. Operators should use caution around dusk and dawn.
If you are operating a vehicle and a deer enters the roadway do NOT attempt to swerve. When an operator swerves to avoid a deer, the vehicle is more likely to strike another vehicle or exit the roadway striking trees or utility poles.
If you strike a deer, remain at the scene and call 9-1-1. An accident report can be completed by Troopers if your vehicle has more than $1,000 in damage or if an involved person has been injured.
