SINGAPORE - From Sept 1, the on-board units (OBU) fitted in vehicles as part of the next-generation Electronic Road Pricing (ERP 2.0) system can be used to pay missed road toll charges.

The feature will be available for motorists whose vehicles are fitted with the OBU that includes the touchscreen display. The Land Transport Authority (LTA) announced the update in a Facebook post on Aug 27.

When there is an outstanding ERP charge, an icon will appear on the home screen of the OBU display.

Payment can then be made directly by pressing the button on the touchscreen display, but only when the vehicle is stationary. The amount will be deducted from the stored value card inserted in the OBU.

Motorists have five days to make payment to avoid a $10 administrative charge. The grace period has been in place since Oct 1, 2024. The LTA said that the grace period is possible because the backend processing costs to handle missed payments have been lowered with the implementation of ERP 2.0. There was no waiver before last October.

When the grace period was introduced, LTA also launched a text notification of failure to pay ERP charge to the mobile number of the registered owner of the vehicle. If no payment is made within the five-day period, a letter will be sent and the administrative charge will apply.

If payment has been made at AXS stations or online, it will take a day before it is reflected on the OBU.

The LTA has introduced new features to the vehicle OBU since installation began in November 2023. These include allowing drivers to temporarily suspend the card reader function when they exit car parks with complimentary parking coupons, displaying real-time traffic information, including road closures for major events, as well as show the availability of parking spaces in major buildings.

Other features to be introduced on the OBU later include paying for usage licences like off-peak cars, tolls at existing Woodlands and Tuas checkpoints, and roadside parking. No details have been given for these features.

The LTA said that around 700,000 vehicles have been fitted with the OBU to date. As at the end of July , there are 1.01 million vehicles in Singapore.

The LTA urged motorists who have not installed the OBUs to do so . It has said it expects the exercise completed by 2026.
