"The prescribed legal limits for drink driving in Singapore is 80 milligrammes of alcohol per every 100 millilitres of blood or 35 microgrammes of alcohol per every 100 millilitres of breath. This is currently similar to the United Kingdom’s prescribed legal limit although they have the additional limit of 107 milligrams of alcohol per 100 millilitres of urine."
