hmm correct lor... 10 bucks..
From 1 June 1999, motorists who pass through an operational
Electronic Road Pricing (ERP) gantry without a properly inserted
CashCard in the in-vehicle unit (IU), or with a CashCard with
insufficient balance to pay for the ERP charges, will receive a
letter requesting them to pay the outstanding ERP charge plus an
administrative charge of $10, within two weeks of the
violation.
after the two weeks.. then it will be 70 bucks...
