Singapore Toll Roads Complete Guide

System: Electronic Road Pricing (ERP) — dynamic time-of-day pricing transitioning from gantry DSRC to satellite GNSS ERP 2.0
Operator: Land Transport Authority (LTA)
Currency: Singapore Dollar (SGD)
Coverage: Expressways (22 active gantries); CBD cordon and arterial gantries currently inactive (SGD 0.00)
Technology: In-vehicle Unit (IU) / ERP 2.0 On-Board Unit (OBU) using CEPAS cards (NETS Motoring Card, FlashPay, EZ-Link) or auto-pay backend services (Foreign IU installation available at SGD 158.70)

Do I Need an IU or OBU for Singapore Tolls? 2026 Update

Yes — all Singapore-registered vehicles must be fitted with a working In-vehicle Unit (IU) or new ERP 2.0 On-Board Unit (OBU) to drive through operational ERP gantries. Passing an active gantry without a working IU or OBU carries an immediate penalty fine of SGD 70.00 per instance.

Rental and Foreign Vehicles: Rental cars are equipped with an IU or OBU. Foreign-registered cars entering Singapore without an IU pay a daily flat-rate ERP fee of SGD 5.00 per operational day (deducted via their Autopass Card upon exit). Alternatively, foreign motorists can purchase and install a permanent IU/OBU for SGD 158.70 at authorized workshops. Note that Autopass cards and VEP RFID tags function exclusively at border checkpoints and cannot be read by overhead ERP gantries.

2026 ERP 2.0 Transition and 2027 Rules: Legacy IUs are being phased out by late 2026. From 1 January 2027, foreign-registered vehicles entering Singapore without an OBU will pay a updated flat-rate ERP fee on operational days: SGD 3.00/day for motorcycles and SGD 10.00/day for all other vehicles.

Singapore Toll Costs: Current ERP Rates 2026

ERP charges are dynamically calibrated by LTA based on quarterly traffic speed monitoring, with rate reductions typically implemented during the June and December school holidays. Of Singapore's ~95 physical ERP gantries, fewer than 25 remain active—all situated on high-congestion expressways. Central Business District (CBD) cordon gantries and most arterial road gantries are currently inactive (SGD 0.00).

Toll-Free Days and Hours:

• Sundays and Public Holidays: 100% Toll-Free across all ERP gantries nationwide.
• Eves of Major Holidays: Gantry operations stop early at 1:00 PM on the eves of New Year's Day, Chinese New Year, Hari Raya Puasa, Deepavali, and Christmas Day.

How to Pay Singapore Tolls and Violation Rules

1. Stored-Value Cards (CEPAS-Compliant):

• Accepted Cards: NETS Motoring Card, NETS FlashPay, EZ-Link Motoring Card.
• Legacy contact-chip CashCards are incompatible with ERP 2.0 OBUs.
• Top up cards at 7-Eleven, Cheers, convenience stores, ATMs, AXS stations, or via mobile banking apps.

2. Auto-Pay Backend Services (Cardless):

• Drivers can link their IU/OBU directly to a credit or debit card via NETS vCashCard or EZ-Link Motoring Service.
• ERP charges deduct automatically from the linked bank card without requiring a physical stored-value card in the slot.

3. Decriminalized Missed ERP Payment Enforcement:

• If a vehicle passes an active gantry with an insufficient card balance, LTA issues an SMS alert.
• Motorists have a 5-calendar-day grace period to pay the exact missed ERP charge with SGD 0 administrative fee.
• If unpaid after 5 days, a physical demand notice is issued adding a SGD 10 administrative fee. Unpaid notices after two weeks escalate to a SGD 70 fine.
• Driving through an active gantry without an IU or OBU installed incurs an immediate SGD 70 fine per gantry pass.

Singapore Expressway Network

Singapore operates ten national expressways (~163 km). Active ERP gantries are concentrated exclusively on peak-congestion expressways:

• CTE (Central Expressway) — Primary north–south arterial through the city center; highest active gantry density.
• PIE (Pan Island Expressway) — Longest expressway (~42 km); active gantries at Kallang Bahru and Bendemeer.
• AYE (Ayer Rajah Expressway) — Active gantries near Jurong Town Hall, North Buona Vista, and Alexandra Road.
• KPE (Kallang–Paya Lebar Expressway) — Active gantry after Defu Flyover towards ECP.
• ECP, MCE, SLE, BKE, TPE — Expressways connecting Changi, Woodlands, and Tampines.
• KJE (Kranji Expressway) — Connects PIE at Choa Chu Kang to BKE at Bukit Panjang (No ERP gantries installed).

Frequently Asked Questions

Do Autopass cards or Malaysian VEP tags work in an IU for ERP?

No. Autopass cards and VEP RFID tags are designed exclusively for checkpoint entry/exit systems (paying VEP fees and Reciprocal Road Charges at Woodlands and Tuas). They cannot be inserted into an IU/OBU or read by overhead ERP gantries.

How do foreign-registered vehicles pay ERP charges in 2026?

Foreign cars without an IU pay a daily flat-rate ERP fee of SGD 5.00 per operational day, deducted via their Autopass Card upon exit. Alternatively, foreign motorists can install a permanent IU/OBU for SGD 158.70. Starting 1 January 2027, flat-rate ERP charges without an OBU will adjust to SGD 3.00/day for motorcycles and SGD 10.00/day for all other vehicles.

Are CBD gantries currently charging tolls?

No. As part of post-COVID traffic monitoring and the ERP 2.0 transition, all CBD cordon gantries (such as Orchard Road and Shenton Way) are currently inactive (charging SGD 0.00). Active charging gantries are located exclusively on major expressways.

What is the penalty for driving through an active ERP gantry without an IU or OBU?

Driving a Singapore- or foreign-registered vehicle through an active operational ERP gantry without a working IU or OBU carries an immediate penalty fine of SGD 70.00 per instance.
