Three people died and 39 others were seriously injured in two separate road accidents in Kokstad in the south of KwaZulu-Natal yesterday.
In the first incident the driver of a speeding truck allegedly lost control of the vehicle and collided with two other vehicles before swerving.
The cause of the accident is still unknown. Then 2km from the accident - about two hours later - a bus carrying 30 passengers on the N2 to Kokstad collided with two other vehicles.
One of the vehicles burst into flames, but its driver and passenger managed to escape unhurt. A person from the second vehicle died instantly.
It is suspected that the black smoke from a veld fire that engulfed the freeway could have caused drivers not to be able to see.
"We could not see anything. I then heard a blast and the bus rolled."
Police are investigating.
