A MOTORIST stopped by Bulgarian police after a minor traffic accident admitted he had drunk 20 litres of beer - and promptly passed out, local TV reported. The man had a blood alcohol reading more than double the level usually considered lethal, bTV TV said. The 25-year old driver, who was not named, registered 0.851 blood alcohol content. Bulgaria's legal limit is 0.05 percent, and 0.40 is often fatal. Bulgarian police have upped the number of road checks lately following a spate of serious accidents. More than 1000 people were killed in road accidents in 2007 in Bulgaria, which has a population of 7.7 million.
