What should a driver do when encountering a pedestrian with a yellow armband marked with three black dots?

When a driver encounters a pedestrian wearing a yellow armband marked with three black dots, it signals that the pedestrian is vulnerable and requires special attention from drivers. This type of armband is typically used to indicate that the individual may have difficulties or challenges in navigating their environment, making them more susceptible to accidents.

Slowing down and stopping if necessary shows awareness and consideration for the pedestrian's safety. It allows the driver to assess the situation, ensuring that they can safely execute their next moves without endangering the pedestrian. This response reflects the fundamental principle of prioritizing pedestrian safety and adhering to traffic regulations that protect vulnerable road users.

In contrast, speeding up to pass before the pedestrian would create a hazardous situation, potentially putting the pedestrian at risk. Continuing to drive without stopping overlooks the necessary caution required when encountering vulnerable individuals. Honking the horn might not be appropriate, as it could startle the pedestrian, leading to confusion or unpredictability in their movements. Emphasizing safety and caution in these scenarios is crucial for preventing accidents and ensuring the well-being of all road users.
