What does this traffic sign require of you?

This traffic sign indicates a warning for pedestrians, particularly children, in the area. It requires drivers to exhibit heightened caution because children may be crossing or playing near the road.

The correct actions in response to this sign include:

1. Greatest alertness: Drivers need to be especially vigilant as the presence of children can be unpredictable.
2. Readiness to brake: Drivers should be prepared to stop suddenly if a child unexpectedly crosses the road.
3. Reduction in speed: Slowing down allows for a quicker reaction time and ensures the safety of pedestrians.

All three responses are important to ensure safety in areas where children are likely to be present, in accordance with German traffic regulations.
