Johannesburg - Four people were left injured after a bakkie rear-ended a truck in the south of Johannesburg, paramedics said on Thursday.
The incident took place on Thursday morning on the N12 Highway in Bassonia.
ER24 spokesperson Russel Meiring said paramedics, along with other services, arrived on the scene to find a truck lying on its side in the right-hand lane of the highway.
"Several gas canisters, that had been on the back of the truck, were found lying across the scene. A small bakkie was found lying approximately 20metres away.
"Upon closer inspection, paramedics found a man, believed to be in his 30s, lying trapped inside the bakkie.. three other men were found walking around on the scene."
Assessments were then carried out by paramedics and it was discovered that the man inside the bakkie had sustained serious injuries while the three other men had sustained only minor injuries.
Meiring said rescue services then had to use specialised equipment to free the trapped man from his vehicle.
"Once freed, paramedics treated the men and provided the critically injured man with advanced life support interventions. A short time later, the critically injured man was airlifted by the ER24 Oneplan Helicopter to a nearby private hospital for urgent treatment.
"The three other men were transported by ambulance to hospitals in the area for further treatment."
The exact cause of the collision is not yet known but Meiring said local authorities were on the scene to carry out further investigations.
