Road users should be cautious as the extreme weather in some parts of the country have resulted in very dangerous driving conditions, the Road Traffic Management Corporation has said.The country has been gripped by freezing weather with rain and snow in the Western and Eastern Cape and the Free State. Poor visibility, heavy rain and snow has kept disaster management teams busy trying to assist vehicles stuck on the roads.An RTMC spokesman said the N1 between Beaufort West and Richmond and the N12 between Beaufort West and Victoria West remained closed on Sunday because of snow."Graders have been brought in to remove the snow. However some of the snow has turned into ice. We urge caution on the roads."'SOME TIME TO CLEAR'Western Cape disaster management teams are trying to reach vehicles stuck in remote areas whose occupants had to sleep in them.The spokesman added: "It will take some time before the snow clears. Travellers should be patient and wait until the weather subsides."Many roads in the Eastern Cape are closed because of flooding.An increase in traffic is expected on the N1 between Polokwane and Pretoria, the N3 between Durban and Johannesburg and the N4 between Nelspruit and Pretoria during the course of Monday, July 16.
