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 CashCard / 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) is legally mandatory. ERP gantries automatically deduct charges from the CashCard or CEPAS contactless card inserted in your IU. Without a functioning IU and sufficient card balance, you will receive a fine.

Key Reality: Rental vehicles already have IUs installed. Tourists driving rental cars simply need to ensure the CashCard in the IU has sufficient balance — top-up at any 7-Eleven, Cheers, or AXS station. Failing to maintain balance results in a SGD 10 administrative fee per deduction failure plus the outstanding ERP charge.

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. CashCard / CEPAS Card (Legacy ERP Gantries):

• Insert a CashCard or NETS FlashPay (CEPAS-compliant) into the IU slot
• Deductions are automatic at each gantry; no PIN or action required
• Top up at 7-Eleven, Cheers, AXS machines, OCBC/DBS ATMs, and NETS kiosks
• Minimum top-up: SGD 10; maximum card 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 for locally registered vehicle owners; managed by LTA-authorised workshops

3. Shortage / Violation Handling:

• If CashCard balance is insufficient, the IU beeps and displays a warning; gantry camera records the plate
• An Administrative Fee notice (SGD 10 + outstanding ERP charge) is mailed to the registered vehicle owner
• Failure to pay the notice results in further enforcement action and potential summons

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?

Malaysian-registered vehicles under the VEP scheme have an RFID tag that serves as their IU. Other foreign vehicles driving in Singapore on a temporary basis must obtain a CashCard-equipped IU through a rental company or LTA-authorised vendor. Foreign plates caught at ERP gantries without a valid IU or OBU will receive an administrative notice.

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?

A SGD 10 Administrative Fee plus the outstanding ERP charge is imposed per failed deduction. If the notice is not paid within 28 days, a summons may be issued. Repeated offenders risk vehicle registration suspension. There is no grace period — the gantry records every pass.

When does ERP 2.0 fully replace the gantry system?

LTA has not announced a fixed decommissioning date for legacy gantries. As of 2026 both systems run in parallel. OBU-equipped vehicles interact with ERP 2.0 infrastructure; non-OBU vehicles continue to use the existing IU/CashCard gantry system until the transition is complete.
