What can affect ability to drive in a similar way to alcohol?

The selected combination of medications and drugs is correct because both can impair your ability to drive, similar to the effects of alcohol. In Germany, the Road Traffic Act (StVG) prohibits driving under the influence of substances that can negatively affect your driving skills. This includes not only alcohol but also certain medications and illegal drugs.

Soft drinks, while they may have caffeine or sugar, do not significantly impair driving abilities in the same way that the other substances do. Therefore, they are not included in the combination that matches the correct answer. Understanding which substances can impair driving is crucial for ensuring road safety and adhering to traffic laws in Germany.
