During a deer drive, when should "standers" shoot at deer?

In a deer drive, "standers" should shoot at deer once they have passed their safe shooting zone. This ensures that the shot is taken only when there is a clear and safe backdrop for the shot, reducing the risk of an accidental injury to other hunters or bystanders. The safe shooting zone is defined by factors such as distance, angle, and the presence of human safety. Waiting until the deer have passed this area maximizes safety and increases the likelihood of a successful and ethical shot. It emphasizes the importance of responsible hunting practices and the adherence to safety protocols while in a hunting party.

The other options may prompt hunters to act prematurely or recklessly, endangering themselves or others, which is why only waiting for the deer to be in the safe shooting zone is appropriate.
