Even ______ alcoholic drink(s) can affect your ability to drive safely.

Explanation

Just one standard alcoholic drink (1.5 ounces of liquor, 5 ounces of wine, or 12 ounces of beer) can raise your blood alcohol content (BAC) to 0.02% or higher. At a BAC of 0.02%, your visual system's ability to track a moving target and your brain's ability to perform two tasks at once will be negatively affected. Note that 0.02% is well below the legal limit. The only safe amount of alcohol is none at all.
