Which of the following is a common myth regarding drinking and driving?

The belief that coffee can sober you up quickly is a common myth about drinking and driving. Many people think that consuming coffee will counteract the effects of alcohol and make them fit to drive. However, this is not accurate; caffeine does not have the ability to reduce blood alcohol concentration or diminish the impairing effects of alcohol on judgment, coordination, and reaction times. While coffee may create a temporary feeling of alertness due to its stimulant properties, it does not improve driving ability or decrease the level of impairment caused by alcohol consumption.

The other options present different misconceptions as well. For instance, the notion that a small drink does not affect driving ability underestimates the impact that even small amounts of alcohol can have on cognitive and motor skills. Drinking water, although helpful for hydration, does not speed up alcohol metabolism and thus won't significantly alter impairment levels. The idea that food eliminates alcohol's effects is misleading; while food can slow the absorption of alcohol into the bloodstream, it does not prevent or reverse the impairing effects once alcohol is in the system. Each of these myths can contribute to poor decision-making in situations involving alcohol and driving.
