Franklin Villca Huanaco attempted to reach his mother in Cochabamba, Bolivia, where she had been serving a prison sentence, authorities said.
He made the two-day journey concealed in a metal container in a truck he believed to be on the way to the city.
The driver, who was bound for Iquique, Chile, was unaware of the stowaway.
The boy hid in a container roughly the length of his body, attached to the underside of the truck, reports say.
Authorities said he had been lucky to survive without food and water and the low night-time temperatures in Bolivia's highlands.
Franklin was found wandering the streets near Iquique and has been taken in by a local family.
He had been living with his father and siblings in Oruro, Bolivia, following his mother's imprisonment for transporting chemicals used to make cocaine, authorities say. (read more)
