Some initial hints for drivers to reduce risk of deer vehicle collisions:
Do take note of deer warning signs, by driving with caution at or below the posted speed limit. Such signs really are positioned only where animal crossing are likely.
Peaks in deer related traffic collisions occur October through December, followed by May. Highest-risk periods are from sunset to midnight followed by the hours shortly before and after sunrise.
Be aware that further deer may well cross after the ones you have noticed.
After dark, do use full-beams when there is no opposing traffic. The headlight beam will illuminate the eyes of deer on or near a roadway and provide greater driver reaction time. BUT, when a deer or other animal is noted on the road, dim your headlights as animals startled by the beam may ‘freeze’ rather than leaving the road.
Don't overswerve to avoid hitting a deer. If a collision with the animal seems inevitable, then hit it while maintaining full control of your car. The alternative of swerving into oncoming traffic or a ditch could be even worse. An exception here may be motorcyclists, who are at particular risk when in direct collisions with animals.
Only break sharply and stop if there is no danger of being hit by following traffic. Try to come to a stop as far in front of the animals as possible to enable it to leave the roadside without panic.
Report any deer-vehicle collisions to the police (who should be able to contact the local person best placed to assist with an injured deer at the roadside)
