Singapore ERP 2.0 OBU Mandate & Road Pricing Guide 2026

ERP 2.0 is being rolled out ahead of its implementation date of 1 January 2027.

The all-vehicle OBU mandate for Singapore-registered vehicles starts on 1 January 2027. It should not be described as though the mandate was already universally in force from 1 January 2026.

LTA stated on 3 February 2026 that about 930,000 vehicles, or more than 93% of Singapore-registered vehicles, had already been fitted with an OBU as of 31 January 2026. LTA also said the installation exercise was on track for completion in 2026.

Physical ERP gantries remain part of the current ERP system during the transition. LTA states that from 1 January 2027 physical ERP gantries will no longer be needed as markers for ERP charging locations under ERP 2.

The correct 2026 description is 'ERP 2.0 transition' rather than 'the old gantry system has already been fully removed.'

Global Navigation Satellite System (GNSS)

The ERP 2.0 OBU detects when a vehicle passes an ERP charging location and calculates the applicable ERP charge. The system does not require a physical ERP gantry at each future charging point.

LTA has stated that ERP 2.0 will initially retain the current cordon- and point-based congestion-pricing framework.

There are no immediate plans to impose distance-based road pricing. LTA states that any distance-based ERP charging remains several years away while the current implementation is stabilised.

ERP 2.0 is intended to support road-use charging and aggregated traffic information. The page should not claim that the system simply acts as a universal continuous GPS tracker without qualification.

The OBU is compatible with existing Electronic Parking System (EPS) carpark gantries. However, not all carparks support backend payment, so motorists are advised to retain a valid CEPAS card where necessary.

The original wording calling the system universally 'contactless toll payment' and claiming that every HDB, URA and private-mall carpark supports every OBU payment method was too broad.

During the transition, the existing congestion-pricing framework continues. ERP charges remain associated with specific charging locations and operating periods rather than a universal nationwide toll.

LTA reviews ERP rates periodically using observed traffic conditions. Rates can differ by location and time.

ERP 2.0 does not immediately introduce universal distance-based charging. LTA has said that any distance-based road pricing is several years away.

Use LTA's current ERP rate table or route information for the exact location and time of travel rather than quoting one static national toll range.

A route can have different ERP charges at different times of day, and rates can change after LTA's periodic review.

From 1 January 2027, ERP charging locations will be detected through the GNSS-based OBU rather than requiring a physical gantry at each location.

LTA is trialling new road signs and markings as visual cues for ERP charging locations.

Until ERP 2.0 is implemented on 1 January 2027, physical ERP gantries remain part of the existing charging system.

The OBU is compatible with existing EPS carpark gantries.

For existing vehicles, the IU number is ported over to the OBU so season-parking arrangements tagged to the IU generally continue without a fresh tagging exercise.

LTA has described additional OBU functions, including roadside electronic parking and payment of selected checkpoint tolls for Singapore-registered vehicles. These should be described as available, current or future according to LTA's latest implementation status rather than as universally live features.

The physical Touchscreen Display can provide more functions than the mobile application, including charging information, payment status, parking availability and available road-safety or traffic alerts.

Foreign-registered vehicles continue to use the applicable Autopass arrangements for entry and exit fees and other charges. Foreign-vehicle ERP arrangements are separate from VEP and GVP.

Foreign vehicles should not be told simply to 'install an AutoPass card or temporary OBU'. Autopass and OBU serve different functions and the applicable arrangement depends on vehicle type and the date.

VEP, GVP, checkpoint tolls and ERP are separate charges with separate rules. They should not be combined into a single 'ERP toll' amount.

LTA states that ERP 2.0 collects vehicle-specific data necessary for payment and enforcement-related purposes and aggregated or anonymised data for transport planning and traffic-management purposes.

ERP 2.0 uses a secured system for communications and transactions. The page should not promise that personal or vehicle data is never collected or stored.

Unauthorised installation, modification, repositioning, removal, repair or related OBU services are prohibited under the applicable rules. Serious cases can attract penalties.

The 2026 legislative amendments provide for penalties of up to S$20,000 or imprisonment of up to 12 months, or both, for serious cases involving unauthorised OBU-related services or serious non-installation/tampering offences.
