How Real-Time BAC Tracking Works
Set Up Profile
Enter your weight and gender to personalize BAC calculations using the Widmark formula.
Add Drinks
Log each drink with the time consumed. The tracker calculates absorption and metabolism rates.
Monitor BAC
Watch your BAC level change in real-time as alcohol is absorbed and metabolized by your body.
Stay Safe
Get safety alerts when BAC exceeds legal limits and know when it's safe to drive again.
Understanding BAC Levels
0.00% - 0.03%
No noticeable impairment. Normal behavior and judgment.
0.04% - 0.07%
Slight euphoria, relaxation. Some loss of judgment and coordination.
0.08% - 0.14%
Significant impairment. Illegal to drive in most countries.
0.15%+
Dangerous level. Risk of alcohol poisoning and serious health effects.
Frequently Asked Questions
How accurate is real-time BAC tracking?
Our tracker uses the medically validated Widmark formula and accounts for metabolism rates. However, individual factors like food consumption, medications, and health conditions can affect accuracy. This tool is for educational purposes only.
Why do I need to enter my weight and gender?
BAC calculation depends on body water content, which varies by weight and gender. Men typically have higher water content (68%) than women (55%), affecting how alcohol is distributed in the body.
How long does alcohol stay in my system?
The average person metabolizes alcohol at about 0.015% BAC per hour. However, this rate can vary based on factors like liver health, age, and drinking frequency.
Can I use this to determine if I'm safe to drive?
This tool provides estimates only. Many factors affect BAC that aren't accounted for in calculations. Never rely solely on any calculator to determine driving safety. When in doubt, don't drive.
What should I do if my BAC is above the legal limit?
Do not drive. Use a designated driver, taxi, rideshare service, or public transportation. Wait until your BAC drops below 0.08% and you feel completely sober before considering driving.
Important Safety Information
Educational Tool Only
This BAC tracker is for educational purposes only. It provides estimates based on general formulas and should never be used as the sole basis for determining fitness to drive or operate machinery.
Safety Guidelines
- Never drive if you've been drinking, regardless of BAC estimates
- Individual factors can significantly affect actual BAC levels
- Food, medications, and health conditions impact alcohol absorption
- When in doubt, wait longer or use alternative transportation
- Seek immediate medical attention if someone shows signs of alcohol poisoning
- Know the signs: confusion, vomiting, seizures, slow breathing, unconsciousness
