YANKTON, S.D.(WNAX)- Longer nights, cooler temperatures and ongoing harvest combine to get more deer moving across roads and highways.

Shawn Steward with Triple “A” South Dakota says lots of drivers are hitting deer.

Steward says those deer hits are expensive.

Steward says there are prime times for deer movements.

Steward says while it may be difficult, its best to hit the brakes if a deer is in front of you and not try to swerve away from the animal.
