Alcohol Limit France: 0.5 g/L & Novice 0.2 g/L — 0.5 g/L

The 0.2 g/L limit applies to novice drivers (first 3 years of licence, 2 years if accompanied driving) and to drivers of buses and coaches in public transport since 2015. From 0.8 g/L the offence becomes a délit (criminal) under the Code de la Route, with up to 2 years in prison and €4,500 fine.

About results
Current BAC

Your Current BAC is the estimated alcohol in your blood, shown in g/L (the French legal unit) or as a percentage. A roadside éthylotest reads breath in mg/L; 0.25 mg/L of breath is the 0.5 g/L blood limit.

Legal limit

The general limit is 0.5 g/L (0.25 mg/L breath), dropping to 0.2 g/L for drivers in their first three years (two with conduite accompagnée) and for bus and coach drivers. Between 0.5 and 0.79 g/L it is a contravention (fine up to €750, −6 points); from 0.8 g/L it becomes a délit under the Code de la Route — up to two years in prison and a €4,500 fine.

Elimination rate

The body eliminates alcohol at roughly 0.15 g/L an hour (about 0.015% BAC) and nothing accelerates it — a café, a cold shower or a meal change how you feel, not the reading. A long apéro-plus-dinner can still leave you over 0.5 g/L the next morning.

Standard Drinks

A French verre standard is about 10 grams of pure alcohol — a 100 ml glass of wine at 12%, a 250 ml demi of beer at 5%, or a 30 ml shot of spirits. Santé publique France advises no more than 10 verres a week, and no more than 2 on any day.

Pure Alcohol

The total pure alcohol (ethanol) your body has absorbed, in grams — the basis for both your verre count and your BAC.

Time vs. Sobriety Table

The table projects your BAC each hour, and with your first-drink time it maps them onto the time of day — useful the morning after, showing when you fall back under 0.5 g/L. Status icons mark which hours are safe to drive.

Sobriety Over Time Graph

How Alcohol Affects You

A reference table linking BAC ranges to their typical effects on judgement, coordination and reaction time — impairment that starts well below the legal limit.

Legal limit reached in / Sober in / Peak BAC

Quick summary estimates:

  • Legal limit reached in: time until your BAC falls below the French 0.5 g/L limit (or 0.2 g/L for novice and professional drivers).

  • Sober in: time until it returns to ~0.00 g/L.

  • Peak BAC: the highest level reached 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.

How we calculate your BAC

The exact formula, step by step

Your result is not a guess. It comes from the Widmark equation, the same formula forensic toxicologists use in court. Here it is, worked through with an example.

BAC = A ÷ (r × W) − (β × t)

where A = grams of pure alcohol, r = body-water factor (0.68 for men, 0.55 for women), W = weight in kg, β = elimination rate (~0.15 g/L per hour), and t = hours since your first drink.

  1. Pure alcohol (A). Three 500 ml beers at 5% ABV hold 3 × 500 × 0.05 × 0.789 ≈ 59 g of pure alcohol.
  2. Body water (r × W). For an 80 kg man: 0.68 × 80 = 54.4.
  3. Peak level. A ÷ (r × W) = 59 ÷ 54.4 ≈ 1.09 g/L — the same as 1.09‰ or about 0.11% BAC.
  4. Subtract elimination. After 2 hours: 1.09 − (0.15 × 2) = 0.79 g/L.

The calculator runs this same equation on your own weight, sex, drinks and timing — the numbers above are only a worked example. Method based on E. M. P. Widmark (1932); results are an estimate, not a legal measurement.

What people actually log

SmartBAC has run over 17,000 calculations in recent weeks. Of every drink people log, beer is the most common by far — about 6 in 10 — ahead of spirits and then wine.

FAQ

How long does it take for alcohol to leave your body?

Your body removes alcohol at a fairly steady rate — roughly 0.15 g/L per hour (about one French verre standard per hour), and nothing reliably speeds this up. Starting from a BAC of 1.0 g/L, it would therefore take in the region of 6 to 7 hours for the alcohol to clear completely; from 1.5 g/L, closer to 10 hours.

That figure is an estimate, not a guarantee. The actual time depends on your weight, sex, metabolism, whether you have eaten, and your general health, so two people who reach the same BAC can sober up at different speeds. Note that you would be over the 0.5 g/L French limit long before your BAC reaches zero — if you started at 1.0 g/L, you'll still be over the limit for about three to four hours. Use our calculator for a personalised estimate.

How can I sober up faster?

The honest answer is that you cannot sober up faster. Your liver breaks down alcohol at an essentially fixed rate, and only time lowers your blood alcohol content. Popular "remedies" — black coffee, a cold shower, fresh air, exercise, a big meal after drinking, or being sick — do not change how quickly alcohol leaves your system.

What some of these can do is make you feel more alert, and that is precisely the danger: feeling more awake while your BAC is still high can fool you into thinking you are fit to drive when you are not. Coffee, for example, masks tiredness without touching your alcohol level. Drinking water is sensible for rehydration and may ease a hangover, but it does not speed up sobering up. The only safe plan is to wait — use our calculator to estimate when your BAC should be back below the 0.5 g/L limit, and then back to zero.

How accurate are French police breathalysers?

French police evidential breathalysers (typically Dräger or Seres devices, approved by the LNE — Laboratoire national de métrologie et d'essais) carry a small margin of error: usually around ±5% on the displayed reading, or ±0.025 mg/L at the 0.25 mg/L threshold. The handheld screening devices used at the roadside are less precise; the evidential machine at the police station provides the legally usable reading.

This tolerance does not give drivers a buffer. If the evidential reading puts you over the limit, you can be prosecuted — the margin is built into how the devices are certified for court use. Consumer-grade éthylotests are noticeably less accurate than police equipment and lose calibration over time, so a borderline reading on a personal device should be treated as "definitely don't drive". The safest course is never to drink and drive rather than to rely on a reading sitting close to 0.5 g/L.
