Life is above all: Any degree of drinking can damage driving ability. This tool calculates only the estimates based on mathematical formulas. couldn't As a legal basis or as a test of actual driving ability. No driving after drinking!

In-depth guide: How does alcohol affect your physical and driving safety?

Blood alcohol concentration (BAC) is an indicator of the proportion of alcohol in human blood. I got it. Change is not only about compliance with the law, but also about responsibility for the safety of one ' s own life and that of others. Alcohol is a neurostatic agent that affects the judgement and reaction speed of the brain even at very low concentrations.

1. Widmark formula: How do we scientifically estimate BAC?

This calculator uses classics. Widmark Formula Conducting estimates: BAC = [Alcohol intake量(g) / (Weight(kg) × Gender系Number)] × 100 - (代Thanks.率 × Time) 。

  • Gender coefficient: Men are about 0.68, women about 0.55 (effects of adhesive fat ratio).
  • Metabolism: On average, the average amount of alcohol is about 0.015 per cent.

2. Effects on humans at different BAC levels

  • 0.02% - 0.05%： Emotional easing, judgment began to decline, and visual functioning decreased slightly.
  • 0.05% - 0.08%： The muscular co-ordination is bad. The reaction time is longer. DUI! Critical point.
  • 0.08% - 0.15%： Loss of balance, vague language, severe loss of judgement, Drunk driving. Scope.
  • 0.30% and above: It could cause a coma or even endanger life.

3. Common error zones in alcohol metabolism

Can strong tea, vinegar or cold showers accelerate metabolism? The answer is... Negative. Yeah. Alcohol 90% The above is metabolized by the liver via ethanol dehydrogenase, a process that is constant. The above-mentioned method may have sobered you, but the blood alcohol levels are not going to drop.

4. Legal and regulatory reminders

According to Chinese law:

  • DUI: 20 mg/100ml ≤ BAC < 80mg/100ml (approximately 0.02 - 0.08%).
  • Drunk driving: BAC 80 mg/100ml (approximately 0.08% or more).

Reminding again: The results of the calculations are for information purposes only. If you drink alcohol, the safest option is always to use a driving or public transport.
