💡 Advice: drink water, eat, and avoid driving until you are well under 0.5 g/L (or 0.2 g/L if you're a novice driver) and ideally fully sober.

About results
Current BAC

Your Current BAC shows your estimated blood alcohol concentration right now, displayed in g/L (the French legal unit) or as a percentage. This reflects how much alcohol is in your bloodstream and is used to assess impairment.

Legal limit

In France, the alcohol limit is 0.5 g/L (50mg/100ml of blood, or 0.25 mg/L of breath) for regular drivers. Novice drivers in their first 3 years and professional drivers must stay below 0.2 g/L. At 0.8 g/L or above, drink driving becomes a criminal offence.

Elimination rate

Your body metabolises alcohol at a steady rate — typically ~0.15 g/L per hour (or ~0.015% BAC/h). Nothing — not coffee, not a cold shower, not exercise — speeds this up.

Standard Drinks

One French verre standard ≈ 10g of pure alcohol — equivalent to a 100ml glass of wine at 12%, a 250ml demi of beer at 5%, or a 30ml shot of spirits at 40%.

Pure Alcohol

This is the total amount of pure alcohol (ethanol) your body has absorbed, in grams. Useful for comparing against weekly limits — Santé publique France recommends no more than 10 standard drinks per week.

Time vs. Sobriety Table

The table lists how your BAC is expected to change with each hour passed — and when a Start time of drinking is provided, it aligns these estimates with the exact time of day you began drinking. Particularly useful for the morning-after check: see at what clock time your BAC drops below 0.5 g/L the next day.

Sobriety Over Time Graph

A visual line chart plotting your estimated BAC decline over hours. It helps you see when your BAC drops below the 0.5 g/L legal limit and then to zero.

How Alcohol Affects You

This reference table shows ranges of BAC and typical effects on your body and behaviour — from mild alertness changes to severe impairment.

Legal limit reached in / Sober in / Peak BAC

These summaries give quick key estimates:

  • Legal limit reached in: the time until your BAC likely falls below the French 0.5 g/L limit.

  • Sober in: total time until BAC reaches ~0.00 g/L.

  • Peak BAC: the highest BAC value recorded in the session.

France Drink Drive Limit & Alcohol Calculator Data

Five factors that determine your result

Weight
Body weight determines how alcohol distributes in the body — more weight means a lower blood alcohol concentration.
Sex
Men and women metabolise alcohol at different rates because of differences in body water content.
Amount
The amount of pure alcohol consumed is the main factor that determines your BAC result.
Strength
A higher strength (%) means more ethanol in the same drink serving.
Time
The time of your first drink shows how BAC changes hour by hour and when you'll be sober again.

Responsible Drinking & the 0.5 g/L Limit in France

Practical tips for safer drinking

Pace yourself
Stick to the "one drink per hour" rule – your liver needs time to process alcohol.
Eat before and while drinking
A solid meal slows alcohol absorption – an empty stomach raises BAC faster.
Drink water
After each alcoholic drink, have a glass of water – it reduces dehydration and health risks.
Don't drive
Even small amounts of alcohol impair reaction time. If in doubt, call a taxi or stay overnight.
