Does coffee help a drinker to sober up?

The assertion that coffee does not make a person safe to drive is based on the understanding that while coffee may temporarily enhance alertness due to its caffeine content, it does not reduce the effects of alcohol in the bloodstream. When a person consumes alcohol, their cognitive and motor functions are impaired, and coffee does not counteract these effects. Thus, even if a person feels more awake after drinking coffee, this does not mean they are sober or fit to operate a vehicle safely. The only true way to sober up is to allow time for the body to metabolize the alcohol.

Other responses may suggest various levels of effectiveness for coffee in improving sobriety. While caffeine can increase alertness, it cannot negate the impairment caused by alcohol. Therefore, relying on coffee as a means to sober up is misleading and can lead to dangerous situations.
