Johannesburg - The South African National Roads Agency (Sanral) announced on Friday that e-tolling in Gauteng would not commence in February as initially planned.
The agency said it was exploring different modalities which would be presented to Transport Minister Sibusiso Ndebele.
Earlier this week Sanral said that that 212 906 Gauteng e-toll account units had been registered by January 10 for phase one of the controversial Gauteng Freeway Improvement Project (GFIP)
Light motor vehicles are expected to be charged R0.40/km, medium vehicles R1/km, "longer" vehicles R2/km, and bikers R0.24/km.
Qualifying commuter taxis and buses would be exempted entirely.
Gauteng e-toll tags would only be operational at the Bakwena toll plaza from February.
GFIP phase one cost about R20bn to complete, with most of it financed from loans.
The tolls have been opposed by a wide range of organisations, including trade unions and business bodies.
