What must you remember as bus driver on duty?

As a bus driver on duty, it is crucial to ensure that your ability to drive is not impaired in any way. According to German traffic rules, you must not consume any drugs or medications that could affect your driving performance while you are working or on stand-by duty. Additionally, you must not start driving if your ability to drive is already impaired by such substances. This is to guarantee the safety of all passengers and other road users. The incorrect option is that you can take any drug without concern; even over-the-counter medications might impair your driving, so caution and awareness are essential. Always prioritize road safety by avoiding any substances that can affect your concentration, reaction time, or judgment while driving a bus.
