DESIGNATE A DRIVER. Before you go to a party or a out for the evening, designate someone in your group who will only stick to non-alcoholic beverages and drive everyone else home safely. Your judgment is the first thing to go once you start to drink, so don't wait until you get to the party. If everyone in your group wants to drink, call a taxicab to take you to the party or bar and have a taxi bring you home. The fare is a real bargain compared to the dangers and costs of drinking and driving.
