In a deer drive, a party of hunters splits into two groups. One group lines up along the edge of the game cover - they're called the posters, and they don't move from their assigned positions. The other group are the drivers. They position themselves on the opposite side of the game cover and walk toward the posters. While walking through the cover, the drivers flush out game animals to the posters. If the drivers move slowly, the animals will also move slowly out of the cover. Usually drivers do not shoot at the animal.
This technique is quite effective for cover that is not too thick. Each of the posters must clearly identify the animal they want to target before shouldering their firearm. The posters have to be careful and know their zone of fire. It's important to wear a blaze orange hat and vest and know where the other posters are located. Always check local laws before you hunt.
