The SA Post Office (Sapo) has expressed confidence that it would be able to deal with an influx of Gauteng e-toll bills, Beeld newspaper reported on Thursday.

"Even if one million motorists decided to use the highways without etags every day, and we received one million e-toll bills per day, our systems would be able to handle it," said Newyear Ntuli, group head of e-business at Sapo.

He said the SA Post Office already handled an average of 450,000 traffic-related post per month.

Last week, Transport Minister Dipuo Peters announced that e-tolling in Gauteng would begin on December 3.

Road users without an e-toll account, or a day pass, have a seven-day grace period to pay from the time he or she passed the gantry. A bill would be sent through the post if the account is not paid within seven days.
