Pedestrians are considered particularly vulnerable in traffic for several reasons:

- **Risk of accidents**: When a vehicle hits a pedestrian, the pedestrian usually suffers very serious injuries. The risk of death is higher on roads outside the city due to the higher speed of vehicles.

- **Limited visibility**: Pedestrian accidents occur more frequently in areas where drivers cannot see pedestrians well due to obstacles. This highlights the importance of drivers paying special attention to pedestrians.

- **Right of way**: Pedestrians have the right of way at pedestrian crossings, sidewalks, and other pedestrian areas. Drivers must yield in these situations to protect pedestrians.

- **Drivers' obligations**: Drivers must avoid distractions and pay special attention to pedestrians, especially the most vulnerable such as children, the elderly, or those with disabilities.

In summary, pedestrians are especially vulnerable to traffic hazards, which justifies the need to pay them special attention to avoid accidents and protect their safety.
