The drink driving laws throughout the UK state that the alcohol limit for drivers is 80mg of alcohol per 100mg of blood, 35μg (micrograms) per 100ml of breath, or 107mg per 100ml of urine. This might seem confusing, which is why it is recommended that you do not drink at all if you intend on driving. Due to the unpredictable nature of the effects of alcohol, there are many factors that could have an effect on your driving.
Although it is incredibly dangerous, drink driving is still a prevalent problem on UK roads. Being caught driving under the influence of alcohol is an incredibly severe offence and is punishable as such. You could face a 12-month ban, an unlimited fine, and a prison sentence.
