High traffic volumes are moving on major routes out of Gauteng as Christmas draws nearer.
Road Traffic Management Corporation spokeswoman Thato Mosena said on Monday: "There are more than 2000 vehicles per hour on the highways.”
Traffic volumes were normal in the Western Cape on Monday but provincial traffic spokesman Jacques Mostert said there were a number of deadly accidents on the roads at the weekend.
Early on Friday, two cars crashed into an earlier accident scene on the road between Laingsburg and Matjiesfontein.
In the first accident, a head-on collision between two cars resulted in the death of both the drivers, a man and woman.
In the darkness, two other cars then crashed into the scene. One person was seriously injured and taken to hospital.
On Saturday morning, a husband and wife died when they lost control of their BMW on the N1 towards Paarl. The man died on the scene and the woman died later in hospital.
Their teenaged daughter is still fighting for her life.
On Sunday a male pedestrian was knocked down and killed on the N1 between Worcester and Touwsrivier.
Limpopo roads and transport spokesman Jimmy Machaka said five people died and another two injured on Sunday night when a speeding minibus collide with a car on the R579 in Nebo.
Eastern Cape, Limpopo, Mpumalanga and KwaZulu-Natal traffic officials said the flow of traffic was steady on Monday. - Sapa
