Eight people were killed on the N3 highway in Harrismith when a truck and two Hyundai H100 bakkies collided on Sunday morning.
The accident happened around 07h30 near the Harrismith golf course.
Two other people sustained serious injuries and were transferred to the nearest hospital.
All the deceased persons reportedly died on scene.
Traffic had to be redirected through Harrismith town as the road was closed to allow accident scene experts to collect evidence.
Preliminary investigations suggest that the driver of one of the bakkies may have fallen asleep while driving and crashed into the truck.
