If that wasn't super heroic enough, the boy then rushes to the aid of his injured grandmother after she was hit by the same out-of-control car.
Little Joao Pedro Nascimento was feared dead after the car ran over him.
But he picked himself up with just a few cuts and bruises on his face and then went to his gran Vilma, 56, as they waited for an ambulance to arrive.
The astonishing scene – captured on CCTV – happened as the pair were walking home from Joao's school in Anapolils, near Goiana, Brazil.
It shows a Chevrolet being struck by a speeding Honda then smashing into a parked VW Golf, which was sent careering into the boy and his grandmother.
Incredibly, Joao was released the same day from hospital after tests. His gran was allowed home the day after Tuesday's horror smash, filmed on a camera overlooking the street.
Vilma, who suffered light wounds to her legs and feet, said: "I feel as if we've been born again. It's a miracle we're still alive.
"Joao doesn't even look as if he's been run over.
"I saw how the car crushed him and he ran towards me but when I saw blood coming out of his nose and mouth I feared the worst.
"I only calmed down when they said in hospital his injuries were superficial.
"I was terrified about the idea of something bad happening to my grandson while I was in charge of him.
"The hand of God helped us and thankfully we're okay."
