Question: What is BAC (Blood Alcohol Concentration)?

Answer options:

  • The amount of beverages a person has consumed in one hour. ✅ The percentage of alcohol in a person's bloodstream.
  • The rate at which a person metabolizes alcohol.
  • The level of ethanol present in a standard drink.

Correct answer: The percentage of alcohol in a person's bloodstream.

It's a key indicator used to determine impairment. Option A refers to intake, not actual concentration. Option C is about metabolism, which influences BAC but isn't BAC itself. Option D defines ethanol, not a person's BAC.
