Final answer:
It is false that drinking strong coffee can help a driver sober up. Alcohol metabolism is a process that occurs over time and cannot be sped up by consuming coffee or other substances.
Step-by-step explanation:
To "sober-up" a driver should drink strong coffee is false. The misconception that coffee can help sober up an intoxicated person is widespread, but alcohol metabolism is a process that can only be completed by the body over time, specifically the liver.
Regardless of coffee consumption or other methods such as taking a shower, the liver must be given enough time to metabolize the ingested alcohol to reduce blood alcohol concentration (BAC) to safe levels. The legal limit for intoxication in many places is a BAC of 0.08, and it takes at least five hours for a person who has reached legal intoxication to sober up. Therefore, exercising patience and waiting is the only true method to ensure sobriety after drinking.
