What is the only thing that can help sober up an intoxicated driver?

The only thing that can help sober up an intoxicated driver is time. When a person consumes alcohol, it enters their bloodstream and affects their cognitive and motor functions. The body metabolizes alcohol at a constant rate, and adding water, food, or caffeine does not speed up this process. While hydration and food might help alleviate some symptoms of intoxication and caffeine may temporarily increase alertness, none of these methods can reduce the blood alcohol content (BAC) or restore the driver's mental faculties to a safe level. Therefore, the only reliable method for sobriety is simply allowing enough time for the body to process and eliminate the alcohol.
