Question #3 What is BAC, and how does it relate to one's driving abilities? A. BAC stands for "Body Alcohol Content" and improves driving skills as it increases. B. BAC stands for "Breath Alcohol Content" and has no effect on driving abilities. C. BAC stands for "Blood Alcohol Calibration" and indicates the legal limit for alcohol consumption while driving D. BAC stands for "Blood Alcohol Concentration"and measures the amount of alcohol in the blood which directly impairs driving abilities as it increases. 5 point

The correct answer is D. BAC stands for "Blood Alcohol Concentration" and measures the amount of alcohol in the blood, which directly impairs driving abilities as it increases.<br /><br />BAC, or Blood Alcohol Concentration, is a measure of the amount of alcohol present in a person's bloodstream. It is used to determine the level of impairment caused by alcohol consumption. As the BAC level increases, a person's ability to drive safely is significantly impaired. The legal limit for BAC while driving varies by country or state, but it is generally set at 0.08% or lower. Driving with a BAC above the legal limit is considered impaired driving and can result in legal consequences, including fines, license suspension, or even imprisonment.<br /><br />It is important to note that even small amounts of alcohol can impair driving abilities. As BAC increases, a person's reaction time, coordination, judgment, and concentration are affected, making it dangerous to operate a vehicle. Therefore, it is crucial to understand the effects of alcohol on the body and to avoid driving if under the influence of alcohol.
