That beep of your on-board unit or card reader every time you drive under the Electronic Road Pricing (ERP) gantry is the sound of heart pain—even more so during peak hours. But that’s the price we pay for driving in Singapore.
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.
There are about 77 ERP gantries in Singapore (though not all are operational at once). ERP rates are reviewed quarterly, with temporary adjustments 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 to $6 at selected times for cars (w.e.f. 1 Sep 2025):
Gantry (location and number) | 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 after Braddell Road, Serangoon Road and Balestier slip road (31, 33, 34) | 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 | |
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 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 larger your vehicle, the more you pay.
- Time. The rates during peak hours can change every 30 minutes to spread traffic flow over a longer period.
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.
For the quarter beginning 1 Sep 2025, there are increases of $1 at the following 5 locations:
Time Period | Current ERP Rates* | ERP Rates** w.e.f. 1 Sep 2025 |
AYE After Jurong Town Hall towards City (Set of 3 Gantries)*** | ||
7:30 - 8:00 | $3.00 | $4.00 |

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.
You should have already gotten a new On-Board Unit (OBU). It replaces the old In-Vehicle Unit (IU). 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! If you haven’t, 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 5-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! There have also been cases where people’s OBUs did not detect the ERP gantry when they drove past it. OBUs have a five-year warranty for any manufacturing defects, so get yours replaced if it’s faulty if not you may get fined!
