Pretoria - The e-toll tariff for light vehicles with e-tags has been reduced to 30c/km, Sanral said on Friday.
This was down from the 40c/km decided on last year, Sanral toll and traffic manager Alex van Niekerk told reporters in Pretoria.
The base tariff for light vehicles would remain at 58c/km.
Van Niekerk was giving a SA National Roads Agency Limited presentation on the Gauteng highway e-toll system.
Part of the presentation was the tariff history.
He said the e-tag tariff for motorcycles had been dropped from 24c/km to 18c/km, for medium heavy vehicles (Class B) from R1/km to 75c/km, and heavy vehicles (Class C) from R2/km to R1.50/km.
Transport Minister Ben Martins said government had proposed that toll fees for e-tag users be capped at R550 a month for light vehicles.
Van Niekerk said only about 0.2 percent of Gauteng road users would pay the e-toll cap.
About 78.5 percent of motorists using the freeway were expected to pay less than R100 a month, using e-tags, he said.
About 91.3 percent would pay less than R200 and 96.3 percent would pay less than R300. - Sapa
