📊 Current BAC
Your Current BAC shows your estimated blood alcohol concentration right now, displayed in promille (‰) — the Croatian legal unit — or as a percentage. This reflects how much alcohol is in your bloodstream and is used to assess impairment.
🚔 Legal limit
In Croatia, the alcohol limit is 0.5 ‰ (0.5 g/kg of blood, or 0.05% BAC) for regular drivers. Young drivers under 24, professional drivers (taxi, bus, lorry, coach), motorcycle riders, and instructors must stay at 0.0 ‰ — absolute zero tolerance. Above 1.5 ‰ the offence becomes most severe, with fines up to ~€2,700 and possible jail up to 60 days.
🧪 Elimination rate
Your body metabolises alcohol at a steady rate — typically ~0.15 ‰ per hour (or ~0.015% BAC/h). Nothing — not coffee, not a cold shower, not exercise — speeds this up.
🍺 Standard Drinks
One Croatian standard drink ≈ 10g of pure alcohol — equivalent to a 100ml glass of wine at 12%, a 250ml beer at 5%, or a 30ml shot of rakija 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 — WHO 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 ‰ 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 ‰ 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 Croatian 0.5 ‰ limit.
-
Sober in: total time until BAC reaches ~0.00 ‰.
-
Peak BAC: the highest BAC value recorded in the session.
