Singapore Toll Roads Complete Guide
System: Electronic Road Pricing (ERP) — gantry-based DSRC transitioning to satellite-based GNSS ERP 2.0
Operator: Land Transport Authority (LTA)
Currency: Singapore Dollar (SGD)
Coverage: Expressways, arterial roads, Central Business District (CBD) cordon
Technology: In-vehicle Unit (IU) with NETS Motoring Card / FlashPay / CEPAS card; GNSS OBU for ERP 2.0
Do I Need an IU for Singapore Tolls? 2026 Update
Yes — if you drive a locally registered vehicle in Singapore, a working In-vehicle Unit (IU) or new ERP 2.0 On-Board Unit (OBU) is legally mandatory. ERP gantries automatically deduct charges from the NETS Motoring Card, NETS FlashPay, or CEPAS card inserted in your IU/OBU (or via backend services like NETS vCashCard). Without a working unit or sufficient card balance, a missed charge notice will be issued.
Key Reality: Rental vehicles already have IUs/OBUs installed. Drivers simply need to ensure the NETS Motoring Card or CEPAS card inserted has sufficient balance (top up at 7-Eleven, Cheers, or AXS stations). Motorists who miss an ERP charge receive an SMS from LTA with a 5-day grace period to settle the amount without the SGD 10 administrative fee.
2026 Update: Singapore's next-generation ERP 2.0 (GNSS-based, satellite) rollout is ongoing. New On-Board Units (OBUs) are being distributed and will eventually replace the legacy gantry system. During the transition period both systems operate in parallel; existing IU holders are not penalised. ERP 2.0 will enable distance-based charging and real-time congestion pricing.

Singapore Toll Costs: Current ERP Rates 2026
ERP charges in Singapore are time-of-day and location-specific. Rates are reviewed quarterly by LTA and adjusted to maintain optimal traffic flow — a charge of SGD 0 means the gantry is active but traffic is free-flowing and no deduction is made. Peak-hour rates on busy corridors such as the CTE and PIE can reach SGD 6.00 per gantry pass.
Typical ERP Rate Ranges by Corridor (2026)
| Corridor / Location | Off-Peak Rate | Peak Rate (Cars) | Notes |
|---|---|---|---|
| Central Expressway (CTE) — CBD entry | SGD 0.00 | SGD 4.00–6.00 | Busiest AM peak gantries |
| Pan Island Expressway (PIE) | SGD 0.00 | SGD 1.00–4.00 | Rates vary by segment |
| Ayer Rajah Expressway (AYE) | SGD 0.00 | SGD 1.00–3.00 | West–CBD corridor |
| East Coast Parkway (ECP) | SGD 0.00 | SGD 0.50–2.00 | Airport–CBD link |
| Kallang–Paya Lebar Expressway (KPE) | SGD 0.00 | SGD 0.50–2.00 | Includes tunnel section |
| Marina Coastal Expressway (MCE) | SGD 0.00 | SGD 1.00–3.00 | Underground; CBD link |
| CBD Cordon Gantries (Orchard, Robinson, etc.) | SGD 0.00 | SGD 0.50–3.00 | Weekday 7:30 AM–8:00 PM |
ERP Rates by Vehicle Class
| Vehicle Class | Multiplier vs Base ERP Rate | Example Peak Charge | Notes |
|---|---|---|---|
| Motorcycles | 0.5× | SGD 0.25–3.00 | Half the base ERP rate at each gantry |
| Passenger Cars / Light Goods Vehicles / Taxis | 1.0× (Base) | SGD 0.50–6.00 | Base rate vehicle class |
| Heavy Goods Vehicles / Small Buses | 1.5× | SGD 0.75–9.00 | 1.5× the base ERP rate |
| Very Heavy Goods Vehicles / Big Buses | 2.0× | SGD 1.00–12.00 | Double the base ERP rate; public service buses exempt |
How Singapore's ERP System Works
Singapore operates the world's first fully operational congestion pricing system, introduced in 1998 as a successor to the Area Licensing Scheme. Every ERP gantry broadcasts a short-range signal; your IU reads it and deducts the applicable charge from the inserted CashCard in real time. No stopping required — the transaction completes at highway speed.
Operating Hours: ERP charges apply only during designated peak periods. Off-peak, overnight, and weekend travel is typically free on expressways. CBD cordon charges operate weekdays 7:30 AM to 8:00 PM and selected Saturdays.
Quarterly Revision: LTA reviews ERP rates every three months. Rates increase when average speeds fall below 45–65 km/h (expressways) or 20–30 km/h (arterial roads) during charged periods, and decrease or become SGD 0 when traffic flows freely. Always check the official LTA website for current rates before peak-hour travel.
How to Pay Singapore Tolls
1. NETS Motoring Card / CEPAS Card (Physical Cards):
- Insert a NETS Motoring Card, NETS FlashPay, or EZ-Link Motoring Card (CEPAS-compliant) into the IU or OBU card slot
- Cardless backend payment services (NETS vCashCard or EZ-Link Motoring Service) can also be linked directly to your credit card
- Top up physical cards at 7-Eleven, Cheers, AXS machines, ATMs, and NETS top-up kiosks
- Minimum top-up: SGD 10; maximum stored balance: SGD 500
2. ERP 2.0 On-Board Unit (OBU — GNSS System):
- Satellite-based OBU tracks vehicle position and deducts road usage charges
- Linked directly to a registered bank account or stored-value account
- Enables future distance-based and time-based pricing flexibility
- OBU installation is free if completed within the LTA-notified 3-month final reminder window; late installations cost SGD 35 for motorcycles and SGD 70 for other vehicles
3. Missed ERP Charges & Grace Period:
- If card balance is insufficient, LTA sends an SMS notification to the vehicle owner
- Motorists have a 5-day grace period to settle the outstanding ERP charge without any administrative fee
- If unpaid after 5 days, LTA issues a demand letter adding a SGD 10 administrative fee; unpaid arrears block LTA transactions like road tax renewal
Recent Changes (2026)
ERP 2.0 Rollout:
- GNSS-based OBU distribution to all locally registered vehicles is actively progressing in 2026
- Legacy gantry ERP remains fully operational during the dual-system transition period
- LTA has confirmed no additional charges for vehicle owners upgrading to ERP 2.0 OBU
Rate Adjustments (Q1–Q2 2026):
- CTE southbound AM peak rates adjusted upward on select gantries following traffic speed monitoring
- Several PIE gantry rates reduced after improved traffic flow in off-peak shoulders
- AYE and BKE rates held steady from Q4 2025 LTA review
Cross-Causeway Travel:
- Malaysian vehicles entering Singapore via Woodlands or Tuas checkpoints are subject to ERP charges on Singapore roads
- Foreign-registered vehicles must have a Singapore-registered IU or arrange payment via the rental agency
- The Vehicle Entry Permit (VEP) scheme for Malaysian vehicles continues; VEP tag doubles as IU for ERP purposes
Singapore Expressway Network
Singapore operates ten expressways totalling approximately 163 km, all subject to ERP charges during peak hours. Key corridors include:
- CTE (Central Expressway) — North–south spine through the CBD; heaviest ERP charging corridor
- PIE (Pan Island Expressway) — East–west backbone; longest expressway at approximately 42 km
- ECP (East Coast Parkway) — Changi Airport to CBD; high tourist usage
- AYE (Ayer Rajah Expressway) — West Singapore and Tuas industrial to CBD
- KPE (Kallang–Paya Lebar Expressway) — Includes Singapore's longest road tunnel (9 km)
- MCE (Marina Coastal Expressway) — Fully underground; connects east and west of Marina Bay
- TPE (Tampines Expressway) — Northeast corridor; links Tampines and Seletar
- SLE (Seletar Expressway) — Northern Singapore; connects Woodlands and TPE
- BKE (Bukit Timah Expressway) — Woodlands Checkpoint to PIE
- KJE (Kranji Expressway) — Tuas Checkpoint to BKE; western industrial access
Planning Your Journey in Singapore
Typical Daily ERP Costs:
- CBD commuter (car, peak in + peak out): SGD 8–18 per day depending on route and timing
- Airport to CBD (ECP route, off-peak): SGD 0–2.00
- Airport to CBD (ECP route, AM peak): SGD 2.00–5.00
- Cross-island PIE travel, non-peak: typically SGD 0
Tips to Reduce ERP Costs:
- Travel before 7:30 AM or after 9:30 AM to avoid the highest AM peak charges on CTE and PIE
- Use arterial roads (still ERP-chargeable on some cordon gantries but often cheaper) for CBD entry
- Check live ERP rates on the OneMotoring portal or LTA's MyTransport.SG app before setting off
- MRT and bus remain the most cost-effective option for CBD travel; capped daily fares apply
Frequently Asked Questions
Can I avoid ERP charges in Singapore?
Yes — travel outside ERP operating hours (generally before 7:30 AM, after 9:30 AM for the AM peak; before 5:00 PM and after 8:00 PM for the PM peak) and you pay SGD 0 on expressways. You can also use secondary roads that bypass ERP gantries, though journey times will be longer.
What if I drive a foreign-registered vehicle?
Foreign-registered vehicles enter Singapore using an Autopass Card for checkpoint entry/exit fees. For ERP roads, foreign vehicles can rent a temporary dual-mode IU or insert their Autopass card into an IU. From 1 January 2027, foreign vehicles without an OBU will pay a flat-rate daily ERP fee automatically deducted from their Autopass card upon exiting Singapore.
Do electric vehicles pay ERP?
Yes. ERP charges apply equally to all vehicle types including electric vehicles. There are no ERP exemptions for EVs in Singapore. EV owners must maintain a functioning IU (or ERP 2.0 OBU) with sufficient balance just like petrol vehicle drivers.
Are taxis and Grab cars charged ERP?
Yes. All taxis and private hire vehicles (Grab, TADA, etc.) pay ERP charges, which are passed on to passengers as a surcharge shown on the meter or ride fare. The ERP surcharge equals the actual gantry charge incurred during the trip.
What are the penalties for non-payment?
Motorists receive an SMS notification from LTA and have a 5-day grace period to pay the missed ERP charge with no administrative fee. If unpaid after 5 days, LTA issues a demand notice with a SGD 10 administrative fee. Outstanding ERP arrears block key vehicle transactions, such as road tax renewal and vehicle ownership transfer.
When does ERP 2.0 fully replace the gantry system?
LTA has mandated that all Singapore-registered vehicles must have an ERP 2.0 On-Board Unit (OBU) installed by 1 January 2027. Legacy gantries are being dismantled progressively through 2026 as the country completes the transition to satellite-based road pricing.
