What is the only guaranteed way to sober up before driving?

The correct response highlights that the only guaranteed way to sober up before driving is to wait for your body to process the alcohol. When alcohol is consumed, it undergoes metabolism in the liver where it is broken down. The rate at which the body can metabolize alcohol is consistent, roughly about one standard drink per hour for the average adult.

Other methods, such as drinking strong coffee, taking a cold shower, or consuming a large meal, may create an illusion of sobriety but do not actually speed up the alcohol elimination process from the body. These methods can lead to false confidence, leading individuals to believe they are sober enough to drive when they are not. Therefore, the only reliable way to ensure you are sober is to give your body time to metabolize the alcohol completely.
