ERP 2 is moving from an in-vehicle change to something drivers will start noticing on the road. LTA says about 1,000 motorists will take part in a user-experience study from June to July 2026, with new signs and blue markings tested at five expressway locations.
The timing matters because ERP 2 starts on 1 January 2027 for Singapore-registered vehicles on public roads. LTA says more than 96% of local vehicles have already been fitted with the On-Board Unit, and the trial is meant to test how well drivers recognise charging points without relying on gantries as visual markers.
Where The Trial Markings Will Appear
- PIE westbound after Kallang Bahru on Woodsville Flyover, across five lanes.
- CTE southbound from Serangoon Road, across two lanes.
- PIE westbound before Eunos Link, across four lanes.
- Marina Boulevard to MCE eastbound, across two lanes.
- Citybound AYE after Jurong Town Hall, across four lanes.
What Drivers Will See
The trial uses combinations of blue ERP signs, oval blue ERP markings, a 25-metre blue road stretch at selected sites, blue edge lines and blue lane-divider treatments. LTA’s Phase 1 test at Bayshore Drive had already checked visibility and skid resistance before this wider expressway trial.
The markings are meant to complement OBU alerts. Under ERP 2, the OBU detects when a vehicle passes a charging location, shows advance alerts and displays the charge after the vehicle crosses the location.
How To Read This As A Motorist
Treat the June-to-July study as a preview of how ERP charging points may look once gantries stop being the main cue. The five trial sites cover different lane counts and road layouts, so regular expressway drivers may see more than one marking style.
