Mystery surrounds the death of a person who was killed after two trucks rolled down an embankment on the N2 between Harrismith and Van Reenens in the Free State.
Netcare 911 said that their paramedics, and other other services, responded to reports of a serious crash early on Saturday morning.
"Upon arrival at the scene they found that two trucks had left the road, gone through the barrier and rolled down the embankment. One of the drivers was trapped in the wreckage," said Netcare spokesperson, Nicholas Dollman.
"Fire fighters from Harrismith used the "jaws of life" to free him from the truck. He was in a stable condition and was transported by a Netcare 911 ambulance to hospital for further medical care. The other truck driver was very lucky to escape with very minor injuries," he said.
Dolman said that a third victim was found outside the trucks and had died from his severe injuries.
"Both drivers alleged that they were alone in their vehicles which led to speculation that the deceased may have been a pedestrian," he said.
The incident is now under police investigation.
