What is a common misconception about driving after drinking coffee?

The belief that coffee can sober a person up is indeed a common misconception. While caffeine may help to combat drowsiness and provide a temporary boost in alertness, it does not reduce blood alcohol concentration (BAC) or alleviate the impairing effects of alcohol on the brain and body. Drinking coffee after consuming alcohol might make someone feel more awake or alert; however, it does not counteract the impairments caused by alcohol consumption. Therefore, a person who has been drinking alcohol can still be significantly impaired and may be at risk of being involved in an accident if they decide to drive after drinking coffee.

This highlights the importance of understanding the actual effects of substances we consume and recognizing that mere stimulation from caffeine cannot undo the risks associated with driving under the influence of alcohol.
