After renting your ideal car, it is important to always carry with you a cash card to be used when you travel through ERP gantries in Singapore.

Motorists who pass through an operational ERP gantry without a properly-inserted CashCard in the IU, or one with insufficient monetary value in the CashCard to pay the ERP charges, will receive a letter within a few days of the violation requesting them to pay the outstanding ERP charge plus an administrative fee of $10, within two weeks from the date of the letter. The administrative fee is reduced to $8 if payment is made electronically via the following channels:

• LTA’s One.Motoring website
• AXS stations
• Self-service Automated Machines (SAMs) at post offices
• vPost
• Automated teller machines
• Telephone and internet banking services

To check out the locations and rates of the various ERP gantries, you can access the ONE.MOTORING - ERP Rates
