Who is not allowed to drink alcohol when driving motor vehicles?

In Germany, the zero-alcohol rule applies specifically to drivers under 21 and those in their probationary driving period. This means these groups are not allowed to have any alcohol in their blood when driving motor vehicles to ensure maximum safety and responsibility. Other drivers are subject to a general alcohol limit but are not completely prohibited from drinking. This rule helps protect inexperienced and newly licensed drivers, who may have slower reaction times under the influence. Understanding this distinction is important for safely following German traffic laws.
