In the footage, a man and small boy, not named but believed to be seven years old, can be seen having a conversation inside the large vehicle.
A third person also appears to be sitting to the side.
Moments into the short clip, the child swaps seats with the adult and gets behind the wheel, while reportedly receiving instructions on how to manevoure the truck.
The seven-year-old then proceed to drive the lorry down a street in Caleta Olivia, Argentina.
The video went viral online and caught the attention of local residents, who reportedly demanded authorities intervene.
The Santa Cruz government requested that the municipality of Caleta Olivia investigate the incident.
The men, one of whom reportedly lives in Trelew, in the video have reportedly had their licenses suspended by Santa Cruz Road Safety.
“A child in the hands of two irresponsible adults who despise rules and life,” the road safety team wrote on Facebook.
“We have already taken measures so that they DO NOT drive anymore!”
Luca Pratti, who works at the Ministry of Security of Santa Cruz, shared the post and added “An aberrant fact. Two adults, completely irresponsible, endangered the lives of those around them, their own and that of a minor child.
“From the Provincial Road Safety Agency we cannot allow these actions and we have already carried out the corresponding measures so that they no longer drive.”
Meanwhile, Road Safety also shared an official statement where the organisation “rejected this type of actions”.
