Blood Alcohol Concentration (BAC)

Blood Alcohol Concentration (BAC) is a measurement of the amount of alcohol in a person's bloodstream, expressed as a percentage. For instance, a BAC of 0.08% means there are 0.08 grams of alcohol per deciliter of blood. It helps assess how alcohol impairment affects judgment, coordination, and reaction times. Different factors, like body weight, gender, and how quickly one drinks, can influence BAC. Most countries have legal limits for driving, typically around 0.08%, meaning that at this level, individuals are considered impaired and unsafe to operate a vehicle.
