Johannesburg - Emergency medical services spokesperson Robert Mckenzie said on Saturday that three people were killed and 20 others injured in accidents on KwaZulu-Natal roads since Friday.
Three people travelling in a bakkie on the R103 near the Escort hospital were killed early on Saturday morning and seven other occupants were taken to hospital, four of them in a critical condition.
In another accident in which a bakkie was involved, nine people were injured when the bakkie they were travelling in was involved in an accident on the N2 near Tongaat on the north coast about 04:00 on Saturday.
They sustained serious and minor injuries and were taken to nearby hospitals.
Two others were injured when two cars collided on the N2 near the Balito offramp just after 04:00. They were taken to hospital for further treatment.
On Friday evening, two people were seriously injured when a heavy goods truck they were travelling in was involved in an accident on the N3 between the Engen and Tugela plaza.
They were taken to the Ladysmith hospital for further treatment.
Mckenzie said the cause of the accidents were not clear and cautioned drivers to be cautious when driving due to the weather conditions.
"The rain, gusting winds and cold temperatures we experienced yesterday [on Friday] look set to continue over the weekend.
"Drivers should slow down, switch head lights onto dim and increase following distances."
