To relieve congestion between 7.30am and 9.30am along the expressways and busy roads, all vehicles passing through ERP gantries are required to pay a toll. An In-Vehicle Unit (IU) is installed in the vehicle and a CashCard (stored value card) is used to pay for tolls. The IU automatically deducts the toll from the CashCard each time the vehicle passes through ERP gantries.
