Electronic Road Pricing (ERP) rates will be reduced by $1 or 50 cents during certain time periods at 12 gantries for the June school holidays. The revised rates will apply from June 1 to June 29. The ERP rates will revert to pre-school holiday charges from July 1, said the Land Transport Authority (LTA) in a news release on Monday.

The 12 gantries include one on the southbound Central Expressway before Braddell Road, and two along Dunearn Road. Rates for other gantries remain unchanged. The LTA monitors traffic speeds on all roads and found that traffic flow at these 12 gantries during the last June holidays was smooth enough to warrant a reduction of ERP rates this year.

In addition, vehicle entry permit operating hours will end earlier at noon on weekdays for June 1 to June 30. Drivers of foreign-registered cars and motorcycles do not have to pay permit fees for the day if they drive into Singapore after 12pm and leave by 2am the following day on weekdays during this period.

The LTA said this is part of an ongoing initiative to attract foreign visitors to Singapore, especially during the local school holiday period. For normal weekdays outside of Singapore's June and December school holidays, vehicle entry permit fees are charged from 2am to 5pm daily except on weekends and public holidays. The existing vehicle entry permit fee is $20 a day for cars and $4 a day for motorcycles.
