When it comes to how much you can drink and still legally drive, the current standard in Texas and all other U.S. jurisdictions has been a blood alcohol content of less than .08 percent. The allowable BAC has been at .08 since the mid-80s and 90s, after traffic safety and other interest groups such as Mothers Against Drunk Driving lobbied for years to have the law passed in every state.
According to the National Transportation Safety Board, however, the .08 standard isn't doing enough to stop drunk driving accidents from killing thousands of people every year. Since the allowable BAC in the many other industrialized countries is .05, the agency has just announced its recommendation that the U.S. follow suit.
Government statistics show that around 30 percent of all fatal traffic accidents involve drunk driving. That is a big improvement since driving while intoxicated first became a major political issue during the Reagan administration, when half of all fatal crashes involved someone who was DWI.
