Johannesburg - The N3 near Katlehong on the East Rand came to a standstill late on Thursday afternoon as motorists joined Cosatu's anti-toll “drive-slow” convoy.
As police tried to get the motorists to speed up they slowed down even more.
Journalists and other people were stopped from parking on the side of the road to work or take pictures as police urged the protesters to drive faster.
Meanwhile, the Johannesburg group of the anti-toll protest, against the tolling of Gauteng's freeways, was heading along the M1 north, past the Booysens off-ramp, towards the CBD.
Traffic was moving slowly as motorists hooted and pumped their fists out of the windows.
Protesters want the e-toll system dropped. Last week the Congress of SA Trade Unions threatened to occupy Gauteng streets and block freeways during the protest.
The Opposition to Urban Tolling Alliance has brought a court application to have the e-toll project scrapped, but a ruling has yet to be made. - Sapa
