Which listed factors affect a driver’s blood alcohol concentration?
Correct answer: D – All three factors
BAC is affected by how much alcohol a person consumes, how quickly it is consumed, and the person’s weight. Consuming more alcohol raises BAC, and rapid drinking gives the body less time to process it. A smaller person generally reaches the same BAC with less alcohol than a larger person.
