The amount of alcohol in the blood is referred to as:
- Implied consent (IC).
- Blood alcohol concentration (BAC). ✓
- Rate of alcohol consumption (RAC).
Answer: B. Blood alcohol concentration (BAC).
The amount of alcohol in your blood is called your blood alcohol concentration, or BAC.
Why this is the answer
The handbook glossary defines BAC plainly: it is the amount of alcohol in your blood. The same entry gives an example, where a BAC of 0.10% means 0.10 grams of alcohol in 100 milliliters of blood. That definition matches the term used throughout the alcohol and drugs section, where BAC limits and BAC test results are discussed, so the term for the alcohol amount in your blood is blood alcohol concentration.
Why the other answers are wrong
- A. Implied consent (IC). — Implied consent is not the amount of alcohol in your blood; the passages do not define it as a measurement of alcohol at all.
- C. Rate of alcohol consumption (RAC). — Rate of alcohol consumption is not the term used for the amount of alcohol in your blood, and no passage defines it that way.
Remember it
Think of the C in BAC as concentration: how much alcohol is packed into your blood, not how fast you drank.
