I was curious if deer-vehicle accidents were common in the basin? I was told yes. I found a site that gave suggestions on how NOT to hit a deer
if a deer does run in front of your vehicle, brake firmly but do not swerve. Swerving can cause a vehicle-vehicle collision or cause the vehicle to strike a pedestrian or potentially deadly fixed object, such as a tree or utility pole
Deer often travel in pairs or groups, so if deer are spotted crossing the road, slow down and be alert that others may follow
Briefly use flashers or a headlight signal to warn approaching drivers when deer or moose are spotted in or near the highway
Do not rely on devices, such as deer whistles, extra lights or reflectors, to deter deer. Research has shown that your best defense is your own responsible behavior
Use caution when driving at dawn or dusk and scan roads and roadsides ahead
