Pedestrians are the most vulnerable element in collisions for several reasons:

- **Severity of injuries**: When a vehicle hits a pedestrian, the pedestrian usually suffers very serious injuries. The situation is even more dangerous on roads outside the city, where vehicles travel at higher speeds, increasing the risk of death.

- **Limited visibility**: Pedestrian collisions occur more frequently in areas where drivers cannot see them well due to obstacles. This highlights the importance of pedestrians taking precautions, such as crossing at pedestrian crossings and waiting on the sidewalk before crossing.

- **Driver precautions**: Drivers must take measures to avoid collisions, such as driving at a moderate speed, especially in the city, and paying attention to pedestrians who may be distracted or in party areas.


- **Safety technology**: There are systems like pedestrian detectors that help prevent collisions by alerting the driver and, if necessary, automatically activating the brakes.


In summary, pedestrians are the most vulnerable in collisions due to the severity of the injuries they can suffer and the need for both them and drivers to take precautions to avoid accidents.
