What is the legal blood alcohol concentration limit before a drink driving conviction enters the picture?
The limit for a driver is 80 milligrams of alcohol per 100 millilitres of blood, or 35 µg, or microgrammes, per 100 millilitres if using a breathalyser test, and finally, the limit when using a urine sample to test for overall alcohol consumption is 107 milligrams per 100 millilitres. Achieving these levels of alcohol in one’s system would require a male of normal weight and size to consume two pints of beer.
