The grandfather, aged 69, and identified by the initials A.B., suffered a sudden heart attack while driving his grandson in his Fiat Punto at around 4:40pm on Monday in the mountain town of Fiuminata, central Italy, Il Messaggero reported.
Realizing what had happened, the boy then had the presence of mind to take control of the wheel and steer the car for 500 metres, managing to dodge passing tourists and residents.
But the boy was unable to stop the car and it crashed into a parked van on the side of the road by a building site.
Thanks to the boy’s quick-thinking he was able to save his own life and no passersby were harmed.
The boy was in shock and taken to the Camerino hospital for a check-up. An initial examination found that he did not suffer any major injuries.
