About results

📊 Current BAC

Your Current BAC shows your estimated blood alcohol concentration right now as a percentage. This number reflects how much alcohol is in your bloodstream and is used to assess impairment.

🚔 Legal limit

In the United States and Canada, the standard legal driving limit for fully licensed adults is 0.08 % BAC. Exceeding this can result in DUI/DWI penalties, including fines and license actions.

🧪 Elimination rate

This shows the assumed average rate your body metabolizes alcohol — typically ~0.015 % BAC per hour. It’s an estimate of how fast your BAC decreases over time.

🍺 Standard Drinks

The number of Standard Drinks represents the approximate number of typical servings you’ve consumed (e.g., one beer, glass of wine, or shot), based on local standards for drink size.

🧴 Pure Alcohol

This is the amount of pure alcohol (in ounces) your body has absorbed so far, giving you a measure of total alcohol consumed.

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. For example, if you started at 6:00 PM, the column will show your projected BAC at 6:00 PM (Now), 7:00 PM (1h), 8:00 PM (2h), etc., so you can clearly see when your BAC is likely to cross legal and safer thresholds as the day progresses. Icons or status indicators show whether the level is safe for driving at those specific clock times, making it easier to plan your departure or rest period.

📈 Sobriety Over Time Graph

A visual line chart plotting your estimated BAC decline over hours. It helps you see when your BAC drops below legal and safer levels.

😵 How Alcohol Affects You

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

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 legal driving limit.

  • Sober in: total time until BAC reaches ~0.000 %.

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

Data used for calculations

To accurately calculate the effect of alcohol on the body, the following important data is required:

  1. Weight (kg): Body mass has a direct impact on alcohol absorption. Higher weight results in slower alcohol effects on the body.
  2. Gender: Women's and men's bodies process alcohol differently. In women's bodies, alcohol breakdown occurs more slowly due to lower levels of enzymes that break down alcohol.
  3. Amount of alcohol consumed (ml): The exact volume of alcoholic beverage consumed must be specified in milliliters.
  4. Alcohol content (%): This indicator shows the concentration of ethanol in the drink. It is an important factor in determining the total amount of pure alcohol consumed.
  5. Time of first drink or start of alcohol consumption (optional). By entering this time, you can not only see how promilles change over time, but also better understand what the promille value is at this moment.

This data is essential for performing an accurate calculation of alcohol's effect on the body and assessing its impact on different individuals.

Legal alcohol limits in Lithuania when driving

For experienced drivers (with more than 2 years of driving experience):

  • When driving a passenger car or motorcycle: up to 0.4 promilles

For novice drivers and professional drivers (with less than 2 years of driving experience):

  • When driving any vehicle: 0.0 promilles (completely prohibited)

Fines for exceeding permitted limits

When exceeding permitted alcohol limits, drivers face various sanctions:

  • From 0.41 to 1.5 promilles: administrative liability, including monetary fine, suspension of driving rights and possible vehicle confiscation
  • More than 1.5 promilles: criminal liability, which may include a fine, longer suspension of driving rights or even imprisonment

It is important to note that any alcohol consumption before driving is dangerous and can cause serious consequences for road safety

Responsible drinking tips

  • Limit the amount of alcohol consumed – follow the "one glass per hour" rule.
  • Consume alcohol while eating to slow down its absorption.
  • Drink a glass of water after each alcoholic drink.
  • Do not drive after consuming even a small amount of alcohol.
