What is a practical time-keeping method to avoid alcohol impairment before driving?

The most effective way to address alcohol impairment before driving is understanding that time is the only reliable method to sober up. Alcohol is metabolized by the body at a relatively constant rate, which means that no matter what you do—whether it's drinking coffee, using apps, or other strategies—your body needs time to process and eliminate the alcohol.

Practically, this means if you've consumed alcohol, the only way to ensure that your blood alcohol concentration decreases safely is to wait. Waiting allows the body to metabolize the alcohol, reducing impairment and allowing for clearer judgment when it's time to drive.

Other methods, like consuming caffeine or using tracker apps, may provide a false sense of security. They do not influence the body’s ability to rid itself of alcohol and can lead to dangerous misconceptions about being ready to drive when you are not. Understanding the importance of time reinforces the responsibility of ensuring one's readiness to drive safely after drinking.
