Drunk driving, also known as driving under the influence, leads to over 10,000 deaths per year in the U.S. As Mothers Against Drunk Driving (MADD), the organization aimed at eliminating drunk driving, puts it, each of those deaths was preventable. If that isn't sobering enough, maybe these statistics are.
What is drunk driving?
The legal definition of drunk driving in the U.S. based on blood alcohol concentration (BAC), which can be measured by blood, breath, or urine tests. Any amount of alcohol in the blood impairs driving ability, but .08 g/dL is referred to as alcohol impaired driving.
.08: BAC in grams per deciliter (g/dL) at which crash risk increases exponentially; and the level at which it is illegal to drive in Washington D.C., Puerto Rico, and all 50 states except Utah. 
.05: BAC level in g/dL at which it is illegal to drive in Utah. 
.01: BAC in g/dL at which you are an impaired driver, with, “decline in visual functions (rapid tracking of a moving target), decline in ability to perform two tasks at the same time (divided attention).”
