⚖️ Drink-driving rules in Russia
Russia has a near-zero tolerance policy. The legal limit is 0.16 mg/L in exhaled breath, or about 0.3 g/L (‰) in blood. This only allows for measurement error, it is not a permitted dose.
| Offence | Penalty |
|---|---|
| Driving under the influence | ₽45,000 fine and licence suspension for 1.5–2 years |
| Refusing a medical test | Same as driving under the influence |
| Letting a drunk person drive your car | ₽45,000 fine and suspension for 1.5–2 years |
| Repeat offence | Criminal case: fine up to ₽300,000 or up to 2 years in prison, car confiscation |
Information as of 2026, not legal advice. Foreign drivers are subject to the same rules.
❓ FAQ
How long does one beer take to leave the body?
A 0.5 L beer (4.5%) contains about 18 g of pure alcohol. For an 80 kg man it takes about 4 hours to reach zero, for a 60 kg woman about 6 hours.
How do ‰ and mg/L relate?
‰ is grams of alcohol per litre of blood. mg/L is milligrams per litre of exhaled breath, measured by police breathalysers. Roughly, mg/L ≈ ‰ ÷ 2.
Can coffee or a cold shower sober me up?
No. The liver removes about 0.1–0.15 ‰ per hour, and nothing speeds it up. Only time helps.
How does the calculator work?
It uses the Widmark formula with a cautious elimination rate of 0.12 ‰ per hour and simulates absorption minute by minute.
