A reader was charged 50 cents when he drove through an Electronic Road Pricing (ERP) gantry at Kallang yesterday, even though he had passed through it before its operation hours.

The clock on the gantry read 8.51am as he was driving through, but it was actually 8.27am, he told citizen-media website Stomp.

Kenneth added: "The Cash- Card transaction slip showed that I incurred an ERP charge at 8.51am before I incurred the next one at 8.43am."

He said that he had checked with the Land Transport Authority but it was unaware of any malfunction.
