However, a few precautions may minimize your chances of injury or damage to your vehicle. Always wear your seat belt. Don't swerve or take the ditch to avoid hitting a deer. Try to brake as much as possible and stay on the roadway. You risk less injury by hitting the deer.
Deer are gregarious.
When you see one cross the road, be on the lookout for a second or third to follow. If you spot a deer ahead, slow down immediately and honk your horn. Pay attention on roadways posted with deer crossing area caution signs. No published research supports the effectiveness of deer whistles on vehicles.
