The Advertising Standards Authority says Sanral is unable to prove it had sold 1.2-million e-tags, despite claiming this in adverts.

Sanral has been ordered to fix billing problems related to the Gauteng e-toll system, says Transport Minister Dipuo Peters.

Sanral says more than 960 000 e-tags have been sold to road users in Gauteng since e-tolling started.

Cosatu seems confident that civil disobedience will prevent the success of e-tolling, despite its offical launch on Tuesday.

A hefty bill awaits non-registered motorists without e-toll accounts who fail to pay for e-tolling within a week.

After warnings that motorists will be charged if they don’t pay e-toll bills, a law firm has offered to defend the first non-compliant e-toll user.

The Opposition to Urban Tolling Alliance has rejected claims that it is encouraging Gauteng motorists to break the law.

Cabinet says it has faith that the public will abide by the law and buy e-tags, calling on Gauteng’s inhabitants to "demonstrate good citizenship".

The South African National Roads Agency Limited says there has been a significant increase in the number of e-tag registrations in Gauteng.

Correctional services is considering electronically tagging some inmates to reduce the prison population, but admit further research would be needed.
