It is **prohibited** for the driver of a vehicle to throw objects out of the window, both on the road and in its surroundings. This is because throwing objects can **endanger the safety** of the road and the people using it, whether they are other drivers or pedestrians.

- **Road safety:** Safety depends on everyone, drivers and pedestrians, collaborating by respecting the rules. Throwing objects can damage the road, hinder the passage of vehicles, or even cause accidents.

- **Drivers' obligations:** Drivers must avoid distractions and behaviors that could cause damage or accidents. This includes not throwing objects that could be dangerous to other vehicles or pedestrians.

- **Loading and unloading operations:** Although loading and unloading operations should be carried out off the road, if they are done on the road, precautions must be taken to avoid causing damage or inconvenience. It is prohibited to leave objects on the road, the shoulder, or pedestrian areas, which reinforces the idea that throwing objects from a vehicle is dangerous and not allowed.

Therefore, the prohibition of throwing objects applies both on the road and in its surroundings to ensure everyone's safety.
