Singapore’s Electronic Road Pricing (ERP) system is an essential part of traffic management. Whether you’re a driver commuting daily or someone planning occasional trips across the island, knowing how to check ERP charges online can help you manage costs and avoid unnecessary tolls.
With the LTA ERP portal and various online platforms now offering real-time information, it only takes a couple of minutes to get updated on gantry rates. Here’s everything you need to know.
What Is the ERP System in Singapore?
The ERP system is an electronic toll collection scheme introduced by the Land Transport Authority (LTA) in 1998 to reduce traffic congestion in high-demand areas during peak hours. ERP gantries are located along major expressways, arterial roads, and central business districts.
Charges vary depending on:
-
Location of the gantry
-
Time of day
-
Vehicle type
The ERP system is automated, so charges are deducted from your IU (In-vehicle Unit) when your vehicle passes a gantry.
Why It’s Important to Check ERP Charges
ERP charges can change periodically, especially during quarterly reviews by LTA based on real-time traffic flow data. If you don’t check in advance, you might get hit with unexpected fees—especially if you’re driving through several gantries.
Knowing the gantry fee checker tools available can help you:
-
Plan alternative routes to avoid ERP costs
-
Travel during non-peak hours to save money
-
Estimate total travel costs for logistics or rideshare services
Step-by-Step: How to Check ERP Charges Online
There are three main ways to check ERP charges in real time:
1. Using the LTA ERP Portal
The LTA ERP portal is the most reliable and up-to-date resource. Follow these steps:
-
Click on “Driving in Singapore”
-
Choose “ERP Rates and Gantries”
-
View gantry locations on an interactive map or search by location
You’ll be able to see:
-
Current ERP rates by gantry
-
Time-based charges
-
ERP operating hours
-
Types of vehicles affected
2. Via ERP Checker Apps
Several third-party apps and navigation platforms integrate ERP checker features:
-
OneMotoring Mobile App (by LTA)
-
MyTransport.SG
-
Google Maps (for estimated toll costs)
-
Grab Driver App (shows upcoming ERP costs)
Always verify ERP data from official apps, as third-party sources may have a time delay in updates.
3. Through Road Toll Lookup Sites
Some Singaporean road toll lookup websites offer full gantry lists and search filters by:
-
Time of day
-
Car type (motorcycle, car, heavy vehicle)
-
Zones (CBD, expressways, etc.)
These websites are useful for route planning, but again, always cross-reference with the LTA portal guide for official rates.
When Do ERP Charges Apply?
ERP charges are typically active:
-
On weekdays
-
Between 7.00 AM and 8.00 PM
-
Peak periods (morning and evening rush hours)
There are no ERP charges on:
-
Sundays
-
Public holidays
-
Certain off-peak hours (e.g., lunchtime)
Future Changes to ERP in 2025
In 2025, LTA has begun rolling out new satellite-based ERP systems under trial. While still in its pilot phase, this next-gen system will eventually replace physical gantries with GPS-based tracking to enable more dynamic and distance-based pricing.
This may affect how you use road toll lookup tools and will likely lead to changes in how ERP costs are displayed online.
Final Tips for Drivers
-
Always ensure your IU is working and topped up.
-
Keep a screenshot or list of gantry fee checker results before your journey.
-
Use official channels like the LTA ERP portal to avoid misinformation.
By learning how to check ERP charges online, you’ll save time, money, and avoid surprises on the road.
