Using AlcoCalc safely

The colours explain the model

Orange and green indicate a mathematical result. Green does not mean it is safe or legal to drive, or confirm that no alcohol is present.

Do not use the estimate to decide whether to drive

If you are unsure, do not drive. Choose a way to travel that does not require you to drive.

Medical and legal questions

The tool does not replace medical care or professional legal advice. This version does not list legal limits or penalties.
