What blood or breath alcohol content would make you legally drunk?

However, some countries have lower legal BAC limits, and some have a zero-tolerance policy for drinking and driving.

For example, in the United States, the legal BAC limit is 0.08% for most drivers. However, in some states, the limit is lower for drivers under the age of 21 or for commercial vehicle drivers.

In Canada, the legal BAC limit is 0.05%.

In Australia, the legal BAC limit is 0.05% for most drivers. However, in some states, the limit is lower for drivers under the age of 25 or for drivers of heavy vehicles.

In the United Kingdom, the legal BAC limit is 0.08%.

It is important to note that even a BAC below the legal limit can impair your ability to drive safely. If you are planning to drink alcohol, please do not drive.
