Blood Alcohol Concentration (BAC) limits

Blood Alcohol Concentration (BAC) measures the amount of alcohol in your bloodstream, expressed as a percentage. BAC limits are legal thresholds that indicate when a person is considered too impaired to operate a vehicle safely. For example, a BAC of 0.08% in many places means 0.08 grams of alcohol per 100 milliliters of blood. Staying below these limits helps ensure safe driving; exceeding them increases the risk of accidents and legal penalties. BAC is affected by factors like weight, amount consumed, and time. It’s a key standard used to enforce drunk driving laws globally.
