Drivers, I’m sure you’d agree that it’s super heart pain every time you drive under the Electronic Road Pricing (ERP) gantry and hear the beep in the card reader, especially during peak hours.
While the purpose of ERP is to ease congestion during peak hours, sometimes we have no choice but to travel during those times. You can’t even escape it if you take taxis or ride-hailing.
As of 2025, there are still about 78 ERP gantries islandwide (though not all are operational at once). ERP rates are reviewed quarterly, with temporary reductions during the June and December school holidays to account for lighter traffic. Now that road traffic has largely returned to pre-pandemic levels, some ERP charges have climbed back to as high as $6—matching the peak rates seen before COVID-19. Another thing to note would be that ERP rates are reviewed quarterly—with temporary reductions during the June and December school holidays to account for lighter traffic.
In this updated 2025 guide, we’ll show you the five costliest ERP gantry locations and their peak charges (for passenger cars), so you can plan your routes or travel times to avoid these “every road pay” moments whenever possible.
We’ve also got you covered on how to avoid getting slapped with an ERP fine—and if one does land in your lap, we’ll show you the fastest and easiest ways to pay it off.

5 most expensive ERP gantries & timings (2025)
ERP rates vary from $0.50 to $6. These are the 5 ERP gantries that charge $4 and above at selected times for cars:
| Gantry | Time | ERP rate |
| CTE Slip Road to PIE (Changi) / Serangoon Road (68) | 08:30 – 08:35 | $4.00 |
| 08:35 – 08:55 | $5.00 | |
| 08:55 – 09:00 | $4.50 | |
| 09:05 – 09:25 | $4.00 | |
| CTE from Balestier Road (34) | 08:05 – 08:30 | $4.00 |
| 08:30 – 08:35 | $4.50 | |
| 08:35 – 08:55 | $5.00 | |

| 08:35 – 08:55 | $5.00 | |
| 08:55 – 09:00 | $4.50 | |
| 09:00 – 09:25 | $4.00 | |
| CTE after Braddel Road (31) | 08:05 – 08:30 | $4.00 |
| 08:30 – 08:35 | $4.50 | |
| 08:35 – 08:55 | $5.00 | |
| 08:55 – 09:00 | $4.50 | |
| 09:00 – 09:25 | $4.00 $3.00 (Lowered price for the June holiday period) | |
| PIE into CTE (42) | 08:05 – 08:30 | $4.00 |
| 08:30 – 08:35 | $4.50 | |
| 08:35 – 08:55 | $5.00 | |
| 08:55 – 09:00 | $4.50 | |
| 09:00 – 09:25 | $4.00 | |
| KPE Southbound after Defu Flyover (50) | 08:05 – 08:30 | $4.00 |
| 08:30 – 08:35 | $5.00 | |
| 08:35 – 08:55 | $6.00 | |
| 08:55 – 09:00 | $4.00 |
If you must drive through these areas, try to do so before the charged periods start or after they end to save money—even a difference of 5 minutes can bypass a $5 or $6 charge. Otherwise, consider taking alternative routes that skirt these gantries, or use public transport during the peak hour whenever feasible.There are a couple more than these 5 that charge $4 and above during certain times but they last for about 30 minutes to an hour.
Understanding ERP rates in Singapore
ERP is charged based on:
- The type of vehicle you drive. The “bigger” your vehicle, the more you pay.
- Time. The rates during peak hours can change every 30 minutes to spread traffic flow.
Apart from quarterly reviews and reduced rates during school holidays, there are no ERP charges on Sundays and public holidays. According to LTA, “ERP stops operating at 1 pm on the eve of New Year’s Day, Chinese New Year, Hari Raya Puasa, Deepavali and Christmas Day.”
For the gantries that undergo review, these are the ones that are usually affected:
- AYE, after North Buona Vista Road (towards Tuas)
- AYE, after Jurong Town Hall
- CTE, before Braddell Road
- CTE, after Braddell Road
- CTE, slip road to PIE
- CTE southbound after Serangoon Road (and PIE)
- PIE, after Adam Road and Mount Pleasant
- PIE, Bendemeer Road and Woodsville Tunnel
- ECP (city)
- KPE, after Defu Flyover
- Thomson Road
- Kallang Road
Usually, the ERP for these gantries are either reduced by $0.50 to $1 or removed entirely. Check the LTA website for the rates of the quarterly reviews.

New ERP 2.0 system to be implemented by end 2025
If you’re a driver, you’ve probably heard that there will be a shift to a new ERP 2.0 system as the existing system has been around for 25 years and it’s time to retire. It will be replaced by a new Global Navigation Satellite System (GNSS)-based ERP 2.0 system.
As such, all Singapore-registered vehicles will need to replace their In-Vehicle Unit (IU) with a new On-Board Unit (OBU). The replacement started with fleet vehicles on 1 Nov 2023 and there will be progressive installation for all other vehicles.
Vehicle owners will get a notification (by email/SMS and letter) from LTA to book their installation appointment. For a free installation, you have to complete it within the 2 months given, so don’t delay! You can check if your vehicle is eligible for a free OBU installation here.
The entire OBU replacement is expected to be completed by the end of 2025.
The new OBU comprises 3 pieces: a Processing Unit, an Antenna Unit, and an optional Touchscreen Display. The touchscreen display alerts you to real-time traffic situations such as accidents, road closures or heavy traffic. It can also support payment of roadside parking and tolls at checkpoints, and alert you when approaching an ERP gantry
You have the choice not to install the touchscreen display and you can download an app to get alerts although it will not offer all the same features. Motorcyclists will have a single-piece OBU.
ERP fines & “administrative fee” ($10 to $70)
If you inadvertently miss an ERP payment, the Land Transport Authority (LTA) will send you an SMS notification, granting a five-day grace period to settle the outstanding charge without incurring the usual $10 administrative fee.
Payments can be made conveniently through platforms like OneMotoring, AXS stations, or the LTA’s digital services portal. Failing to pay within this grace period will result in a formal notice requiring payment of the ERP charge plus the $10 fee.
If the payment remains unsettled, a $70 fine will be imposed.
To pay ERP fines, you can use the following methods:
- OneMotoring Portal: Visit the OneMotoring website to pay your fines online using SGQR PayNow or eNETS debit.
- AXS Stations: Utilise AXS self-service kiosks, AXS e-Station, or AXS m-Station mobile app to make payments.
- LTA.PROMPT e-Service: Access the LTA.PROMPT portal to pay fines using your notice number and credit card.
Can you appeal your ERP fine?
Yes. Simply write to LTA—skip the sob story that seems to be the norm for speeding and parking offences—and appeal for a waiver.
People have tried more than once and got their admin fee waived, which is better than nothing.
The bottom line is, just make sure that you have enough money in your card and it’s inserted properly! Hopefully, the new OBU will address existing issues. The authorities surely wouldn’t want you to miss out on paying ERP!
