What is the speed limit when passing a stopped school bus letting children off?

Answer: B — 20 kph

When passing a stopped school bus that is letting children off, the correct speed limit is 20 kph. This specific speed limit is in place to ensure the safety of children who may be crossing the road to board or exit the bus. At this reduced speed, drivers have a better chance to react in case a child unexpectedly runs into the road. The 20 kph limit allows for increased vigilance and the ability to stop more effectively should the need arise. The chosen speed also reflects the significant responsibility drivers have when it comes to the safety of children, emphasizing the importance of caution in these situations. In areas where school buses are present, adhering to this limit helps foster a safer environment for young passengers.
