From October 2026, motorists will progressively see new Electronic Road Pricing (ERP) road markings and road signs across Singapore, ahead of the launch of the ERP 2 system on 1 January 2027. With the transition to ERP 2, all Singapore-registered motor vehicles must be fitted with the ERP 2 On-Board Unit (OBU) to travel on public roads in Singapore. To date, more than 98% of eligible Singapore-registered vehicles have been fitted with the OBU.
2. The ERP 2 system uses Global Navigation Satellite System technology, eliminating the need for physical gantries on Singapore’s roads. The OBU detects when a vehicle passes an ERP charging location and calculates the applicable ERP charges.
New Visual Cues for ERP Charging Locations
3. With physical ERP gantries no longer serving as visual markers from 1 January 2027, LTA will introduce a new set of road markings and road signs to help motorists identify ERP charging locations. These visual cues will complement OBU notifications, to alert motorists before they enter an ERP charging location, provide information on prevailing ERP charges, and indicate the amount charged when motorists pass through a charging location.
4. To ensure the ERP markings are clearly visible to motorists, two oval blue ‘ERP’ symbols will be painted on each lane of arterial and slip roads. On expressways, where motorists travel at higher speeds, three symbols will be painted on each lane to provide greater visibility. A new “ERP Charge Zone” road sign will also be placed at the start of each ERP charging location as an additional visual cue for motorists. Please refer to Annex A for an illustration of the new set of ERP 2 road markings and road signs.
5. From March to July 2026, LTA conducted a two-phase user experience study to assess the effectiveness of different sets of road markings and road signs, with the second phase being a more comprehensive test at five expressways and arterial roads representing different traffic and road conditions. About 1,000 motorists participated in this second phase of the study, which was conducted from 1 June to 31 July 2026 across five expressways and arterial roads.
6. The study found that road markings and road signs help motorists identify ERP charging locations in a gantry-less environment. Among the road marking designs tested, including a 25-metre stretch of road painted in blue and a 25-metre line painted in blue at the sides of the road (along with its corresponding lane dividers), the oval blue “ERP” symbol emerged as the preferred option, achieving high visibility under different traffic and weather conditions, while being easily understood by motorists as a visual cue for an ERP charging location.
7. Implementation of the new road markings and road signs will begin progressively from October 2026 across the existing 33 ERP operational locations. The works will be completed ahead of the transition to ERP 2 on 1 January 2027.
Progressive Removal of ERP Gantries
8. From October 2026, LTA will also progressively remove physical ERP gantries across Singapore. To support satellite connectivity, ERP gantry frames may be retained and repurposed with roadside units (RSUs) at some locations. Please refer to Annex B for a photo of a gantry with RSUs attached.
9. The works will be carried out in two phases. The first phase will remove the 62 non-operational ERP gantries. The remaining 33 operational ERP gantries will be removed after gantry-based ERP charging ceases on 31 December 2026.
10. The modification or removal of all 95 ERP gantries is expected to be completed by June 2027.
Enforcement Against Vehicle-Related Offences
11. The ERP 2 system is designed primarily for payment and charges. It will also enhance LTA’s ability to manage traffic across Singapore, and give LTA better tools to detect and enforce vehicle-related offences. As part of existing enforcement efforts, LTA uses ERP 1 gantry records to detect vehicles that should not be used on our roads, such as deregistered vehicles. We will continue to use ERP 2 to enforce against vehicle-related offences, such as the provision of illegal cross-border taxis services, to ensure safer roads for all users. ERP 2 can also be potentially used for enforcement against speeding offences, but further enhancements are needed before any such use. Access to and use of all ERP 2 data will be limited to authorised purposes and subject to strict safeguards governing its collection, use, and security.
12. There will be no change to the current congestion pricing framework, where ERP rates will be regularly reviewed quarterly, with the next review in mid-November. LTA will continue to monitor traffic conditions and introduce appropriate congestion management measures where necessary.
