What can be the effects of even small quantities of alcohol?

Your answer is fully correct because even small amounts of alcohol can affect driving ability in multiple ways. According to German traffic rules, alcohol can delay your reaction times, making it harder to respond quickly to hazards. It can also lead to reckless driving by impairing judgment and increasing risk-taking behavior. Additionally, alcohol can reduce your hearing and vision capabilities, which are essential for safe driving. Understanding these effects helps explain why any alcohol consumption before driving is dangerous and often strictly regulated.
