Electronic Road Pricing (ERP) charges vehicles that pass through an ERP charging point during operating hours. The rate depends on the vehicle type and the time it enters the gantry; peak-hour rates can change in half-hour blocks. LTA reviews rates every quarter and adjusts them during the June and December school holidays, based on traffic conditions. Check LTA's live ERP Rates service for the current location, time, and vehicle rate rather than relying on a saved rate table (OneMotoring, Electronic Road Pricing).
As at 15 October 2026, ERP charges do not apply on Saturdays, Sundays, or public holidays. LTA's detailed operating-hours section says ERP stops at 1 pm on the eves of New Year's Day, Chinese New Year, Hari Raya Puasa, Deepavali, and Christmas Day. The page's summary still names Hari Raya Haji, so LTA's two sections remain inconsistent; check LTA's current operating-hours information before relying on a Hari Raya eve closure. Operating periods and gantry rates vary; check LTA's current ERP Rates service before travelling (OneMotoring, Electronic Road Pricing).
Paying current ERP charges
Until the transition to ERP 2.0 on 1 January 2027, Singapore-registered vehicles use either an In-Vehicle Unit (IU) or the new On-Board Unit (OBU) at operating gantries. A Singapore-registered vehicle driven through an operating gantry without either unit incurs a $70 penalty for each gantry; this is separate from the $70 fine for failing to pay a missed-charge notice described below (OneMotoring, Electronic Road Pricing). The ERP charge is deducted from a stored-value card inserted in the unit, or paid through a linked backend-payment service. Check that the unit works and that the payment method is active and has sufficient value before driving through an operating gantry (OneMotoring, Electronic Road Pricing).
The OBU accepts CEPAS cards, including NETS FlashPay, NETS Motoring Card, EZ-Link Motoring Card, and Autopass Card; regular CashCards used in current IUs are not compatible with the OBU. LTA also lists backend services for ERP payments. Some carparks may not support backend payment, so LTA advises keeping a card available for parking. LTA says the complimentary NETS Motoring Card supplied during OBU installation is for tapping at private carparks that do not support the Electronic Parking System; the card is provided on a limited basis (OneMotoring, ERP 2.0).
Missed payments
Under the current process, LTA sends an SMS after a missed ERP payment. Pay the missed ERP charge within 5 days of the SMS to avoid the $10 administrative charge. If it remains unpaid after the grace period, LTA sends a notice requiring payment of the ERP charge plus the $10 administrative charge by its due date. Failure to pay by then results in a $70 fine (OneMotoring, Electronic Road Pricing; OneMotoring, ERP 2.0).
For an OBU with a display, an outstanding-payment icon appears immediately after a missed charge and is greyed out while the vehicle is moving; payment through the display is available only while stationary. LTA sends SMS notifications around 2–3 days after a missed charge. Payment through the OBU display by 5 pm on the day before the SMS is scheduled prevents that SMS. LTA describes this as an effective 7-day grace period for OBU users; IU users have 5 days after the SMS. LTA says payment status on OneMotoring and AXS is synced daily, so a payment may take until the next day to appear there (OneMotoring, ERP 2.0).
The ERP grace period also applies to foreign-registered vehicles. A foreign vehicle owner does not receive LTA SMS notifications; if the vehicle has an OBU, missed charges can be paid through it (OneMotoring, ERP 2.0).
From 1 January 2027, LTA says missed ERP charges will be treated as an administrative matter rather than a traffic offence. The vehicle owner will be responsible for settling the charge. If the charge and $10 administrative fee are not paid within 5 days of LTA's SMS, the owner will be unable to transact with LTA until payment is made (LTA, Amendments to the Road Traffic Act to Facilitate ERP 2.0 Transition).
ERP 2.0 transition
From October 2026, LTA is progressively rolling out new visual cues at the existing ERP charging locations ahead of the ERP 2.0 transition. The cues comprise two oval blue “ERP” symbols in each lane on arterial and slip roads, three in each lane on expressways, and an “ERP Charge Zone” sign at the start of each charging location. LTA says they will complement OBU notifications by identifying charging locations, giving motorists advance notice, showing prevailing charges, and indicating the amount charged when vehicles pass a location. Implementation will cover the 33 existing operational locations and is scheduled to finish before 1 January 2027. The transition does not change the current congestion-pricing framework (LTA, New Road Markings and Signs to Support Transition to ERP 2).
From 1 January 2027, all Singapore-registered motor vehicles must have an ERP 2.0 OBU installed to travel on public roads, subject to LTA's listed exceptions: vehicles not allowed on mainland public roads; vehicles on Restricted Use Scheme (including airport, port, Pulau Ubin and offshore-island vehicles, and vehicles on lay-up or Keeping Scheme status); non-mechanically propelled trailers; and Classic/Vintage vehicles. If a vehicle on lay-up status is reinstated during the installation exercise, LTA says it will be scheduled for an OBU; after the exercise ends, the owner must arrange installation within 5 calendar days of reinstatement. Classic/Vintage owners may opt for an OBU; without one, they pay a flat ERP fee for each operational day on Singapore roads. The fee is $3 for Classic/Vintage motorcycles and $10 for other Classic/Vintage vehicles, payable with the e-day licence by the next day. Installation is optional and free before 31 December 2026, subject to technical feasibility (OneMotoring, ERP 2.0).
LTA says eligible Singapore-registered vehicles registered before 1 May 2024 can install the OBU free during the transition. Each eligible motorist's invitation gives a six-month free-installation window; missing it triggers a reminder with an additional three months of free installation. After that, installation fees of $35 for motorcycles and $70 for other vehicles, excluding GST, apply before the OBU becomes mandatory on 1 January 2027. LTA also says motorists may book installation before receiving their notification and should use the booking service to check eligibility and find an authorised workshop for the vehicle's make (OneMotoring, ERP 2.0).
OBU data and privacy
LTA says the OBU is operational only in Singapore. It says vehicle-specific data will be used for payment charges and enforcement, such as non-payment of ERP charges; data shared for policy and planning will be anonymised or aggregated. LTA also says it has safeguards against unauthorised access to personal data (OneMotoring, ERP 2.0).
Foreign-registered vehicles
Foreign-registered vehicles still have to pay ERP when using ERP-priced roads during operating hours. Under the current arrangement, foreign cars may use a $5 flat-rate ERP fee per day, deducted from the Autopass Card when leaving Singapore, or use an IU. Other foreign-registered vehicle types generally need an IU for ERP-priced roads (OneMotoring, Electronic Road Pricing).
Foreign-registered vehicles are not required to install an OBU, but may opt to do so from 1 April 2026. Until IUs are phased out at the end of 2026, vehicles for which LTA requires an IU must use the current IU-based arrangement when using ERP-priced roads. LTA specifically says foreign-registered goods vehicles, taxis and buses need an IU and a stored-value card with sufficient funds; the IU accepts NETS CashCard, CEPAS cards and Autopass Card. A foreign passenger car may instead use the current $5 daily flat-rate arrangement described above. A foreign vehicle type that is required to use an IU but passes an operating gantry without one incurs a $70 penalty for each gantry; this is separate from a missed-charge fine (OneMotoring, Electronic Road Pricing).
From 1 January 2027, a foreign-registered vehicle entering without an OBU will pay a flat fee for each ERP operational day it travels on Singapore roads: $3 for a motorcycle and $10 for other vehicles, including goods vehicles, taxis and buses. LTA says the accumulated fee is deducted from the vehicle's Autopass Card when it leaves Singapore; the driver must have sufficient stored value and present the card at the checkpoint (OneMotoring, Electronic Road Pricing; OneMotoring, ERP 2.0).
Coverage debt
- ERP rates change with traffic conditions. This article does not reproduce the live gantry-by-gantry rate table; use LTA's current ERP Rates service.
- LTA's ERP page still gives conflicting Hari Raya names for the 1 pm eve closure: the detailed operating-hours section says Hari Raya Puasa, while the summary note says Hari Raya Haji. Confirm the relevant date with LTA.
- LTA lists exceptions to the Singapore-registered OBU requirement and special treatments for some restricted-use and Classic/Vintage vehicles. Confirm the current status for an individual vehicle with LTA.
