For pedestrians pushing a cart, it is important to know where they should walk to ensure their safety and that of others. Here we explain the correct options:

- **Pedestrian areas**: Pedestrians should walk on the sidewalks whenever possible. This includes those pushing hand carts, baby strollers, or wheelchairs. Sidewalks are designed for the safe transit of pedestrians and should be the first option.

- **Shoulder**: If the sidewalks are too narrow or blocked, pedestrians can use the shoulder. The shoulder is the lateral part of the road not intended for motor vehicles. It is a safe option when sidewalks are not available.


- **Roadway**: In situations where both sidewalks and shoulders are blocked or insufficient, pedestrians can walk on the roadway. However, they must do so with caution and always on the right, to avoid interfering with vehicle traffic.

These options ensure that pedestrians pushing a cart can move safely and efficiently, adapting to the conditions of the environment.
