At what rate does Blood Alcohol Concentration (BAC) drop once it reaches its peak?

The rate at which Blood Alcohol Concentration (BAC) drops after reaching its peak is commonly accepted to be approximately 0.015 grams per deciliter per hour. This figure is based on numerous studies and averages across populations, indicating how the body metabolizes alcohol after consumption.

This metabolism involves the liver breaking down alcohol, and various factors such as age, weight, gender, and overall health can influence the exact rate for an individual. However, for general purposes in standardized testing and educational contexts, 0.015/hour is the standard figure used.

The other rates offered in the options are higher than the established average, which could lead to misconceptions about how quickly alcohol is eliminated from the system. For practical applications, understanding this rate is essential for law enforcement and healthcare professionals as they assess and address situations involving intoxication.
