How many beers or glasses does it take to test positive? The exact amount of alcohol that will cost you a fine

Many drivers wonder about the amount of alcohol needed to exceed the permitted limit in a breathalyzer test. The answer is not straightforward, since blood alcohol concentration depends directly on factors such as sex, body weight, or whether the drink is fermented or distilled. However, DGT (Dirección General de Tráfico) calculations show that, as a general rule, the doses considered usual are more than enough to give a positive result.
