What is the prescribed blood alcohol limit in England and Wales?

Answer: A — 80

In England and Wales, the legal limit for blood alcohol concentration when driving is 80 milligrams of alcohol per 100 millilitres of blood. This is the threshold used to determine if a driver is over the limit for drink-driving offences. The other numbers given aren’t the standard blood limit for these countries. For context, the breath test has a different equivalent limit (35 micrograms per 100 millilitres of breath) and a separate urine limit (107 mg/100 ml), but the blood limit remains 80 mg/100 ml.
