DEER!

From BoardGameGeek:

DEER! is a slap-jack style game that simulates driving on a Colorado Highway and reacting to the various wildlife that crosses their path. On each card flip, players must react and determine how to respond to the situation on the card! Players set out the stop, slow, and go cards in the middle of the table. If there is a deer, elk, or moose in the road, players race to slap STOP. If the deer, elk, or moose are on the side of the road, slap SLOW. And if the road is clear, slap GO. The first player to slap the correct reaction claims the card. At the end of the game, the player with the most cards wins. -description from designer
