What is a basic preventive measure to avoid alcohol impairment when driving?

Choosing a sober driver is a fundamental preventive measure to avoid alcohol impairment when driving. This approach ensures that, regardless of how much alcohol someone else may consume, there is a responsible and sober individual to handle the driving tasks. Designating a sober driver removes the risk of impaired judgment and coordination associated with alcohol consumption, making it one of the most effective strategies for promoting road safety.

Other options, while they may contribute to reducing the effects of alcohol, do not fully eliminate the risk of impairment. For instance, drinking plenty of water can help to some extent by preventing dehydration but does not counteract the effects of alcohol on judgment and reflexes. Eating a full meal might slow the absorption of alcohol, but it does not guarantee that a person will remain unimpaired. Limiting alcohol to one drink can help, but even one drink can affect individuals differently based on various factors such as weight, tolerance, and the rate of consumption, making this option less reliable. Hence, having a designated sober driver is a definitive way to ensure safety on the roads.
