When approaching **children** or **elderly people** on the road, it is crucial to take precautions to avoid putting them in danger. These two populations are especially vulnerable to traffic accidents for several reasons:

- **Children**:
- They are shorter, making it difficult for drivers to see them and for them to see traffic.
- They have less perception of danger and do not know traffic rules well.
- Most accidents occur when they leave school, a time when they may be distracted.

- **Elderly people**:
- They may have difficulty hearing approaching vehicles due to ambient noise.
- They find it harder to judge the speed of vehicles and distinguish traffic light colors.
- Street conditions, such as poor lighting or high curbs, can complicate safe crossing.
- They have more accidents when they are alone, as they are more careful when with children.

Since both groups are at a higher risk of accidents, it is essential for drivers to be especially careful and attentive when approaching them, ensuring they are not put in danger.
