Hi. All I need some urgent advice. Just came back from my first drive to Singapore yesterday and forgot to tap the Autopass at exit. Also the immigration officer did not advise me and opened the barrier so I drove to the JB side, using the touch n go at that toll. I was in Singapore for just 5 days. From what I understand the ERP should be free, but. Should have paid $1.20 at the toll. So now how? Will I have any problem when I drive for another visit later this year?
