Blood Alcohol Concentration

Blood Alcohol Concentration (BAC) measures the amount of alcohol in your bloodstream, expressed as a percentage. For example, a BAC of 0.08% means that 0.08% of your blood's volume is alcohol. BAC influences your coordination, judgment, and reaction times; higher levels impair these functions progressively. Factors like body weight, gender, how much you’ve eaten, and drinking speed affect BAC. Law enforcement often uses BAC levels to determine intoxication for legal purposes. Maintaining a low or zero BAC is essential for safety, especially when driving or operating machinery.
