Final answer:
When your BAC goes up to 0.17%, your chances of causing a car crash increases to 50 times more likely than if you were sober.
Step-by-step explanation:
When your BAC goes up to 0.17%, your chances of causing a car crash increase significantly, posing a severe risk to both yourself and others on the road. Although the exact multiplier is not provided in the question, we know that the risk of a crash escalates rapidly as the BAC level rises.
According to legal and health guidelines, a BAC level of 0.08% is generally considered legally dr*nk in the United States, and as BAC levels increase, so does the level of impairment and the risk of an auto accident. With a BAC of 0.17%, an individual is more than twice the legal limit, and their chance of causing an accident is exponentially higher than when sober.
