After you stop drinking, how does BAC typically change per hour?

Explanation:
BAC typically declines at a fairly steady pace once you stop drinking, as the liver metabolizes the alcohol. The average elimination rate is about 0.015 percent per hour. That means your BAC drops gradually, not quickly—for example, from 0.08 it would take roughly five to six hours to fall toward zero, though the exact time varies with factors like body weight, food in the stomach, and liver health. The other numbers aren’t the typical pace you should expect, so 0.015 percent per hour is the best estimate. Remember, impairment can linger even as BAC falls, so don’t assume you’re safe to drive just because some time has passed.
