Under Argentine traffic law, what is the right-of-way status of pedestrians crossing at an intersection on a designated crosswalk (senda peatonal)?

1. Pedestrians must always wait and yield to all motor vehicles
2. Pedestrians have absolute right-of-way (Prioridad absoluta de paso), and drivers must stop to allow them to cross safely
3. Pedestrians only have right-of-way if they are carrying a white cane
4. Vehicles have right-of-way if they are making a right turn
