Motorists on the R300 in Cape Town on Monday morning encountered fellow motorists veering out of lanes and into oncoming traffic to avoid protest action ahead of them.
According to police, there were reports of burning tyres and barricaded roads in about 10 areas in the city.
Some were a continuation of land invasion protests and others were related to a call, from the group Gatvol Capetonian, for "peaceful" disruptions to morning traffic in an effort to raises awareness about the plight of backyard dwellers.
In a video on social media, motorists driving on the R300 south, towards Stellenbosch, had to make a u-turn and drive in the direction of oncoming traffic.
City of Cape Town traffic services spokesperson Maxine Jordaan confirmed the incident to News24 on Monday.
She said the R300 in the vicinity of the Stellenbosch Arterial was volatile with intermittent road closures.
"Motorists need to have patience and proceed with caution at all times," Jordaan said.
So far, five people have been arrested following protests in Steenberg, Bishop Lavis, Lwandle, Eerste River, Kraaifontein, Mitchells Plain, Bellville South, Atlantis, Delft and Mamre.
Police spokesperson Brigadier Novela Potelwa said police, metro police and traffic officials were opening roads.
