Sanral has warned motorists of additional costs if they do not pay their e-tolls bills within seven days.
Gauteng motorists not registered for e-tolls should pay their e-toll bills as soon as possible to avoid being charged more, the SA National Roads Agency Limited (Sanral) said on Sunday.
"When you do not have an e-tag ... and if you do not pay within the stipulated seven days, there is an additional cost, which could be three times the standard tariff, incurred," spokesperson Vusi Mona said in a statement.
Motorists who did not pay within the seven day grace period, from the date of first gantry pass, would qualify for a 60% discount on the invoice amount if they paid within 30 days of the invoice date.
Mona said the toll collection process had three phases.
The first was the seven day grace period, followed by the violations processing centre's debt collection process and lastly prosecution, as per the Criminal Procedure Act.
He said prosecution would begin when the motorist was uncooperative following a final letter of demand from Sanral.
Mona reiterated that motorists with e-tags would get discounted rates and benefit from the monthly cap on e-toll fees. - Sapa
