Motorists coming from Malaysia's state of Johor form a queue as they approach the immigration checkpoint to enter Singapore on Mar 31, 2023. SINGAPORE: Older foreign motorcycles will soon be disallowed on Singapore's roads, while foreign commercial diesel vehicles must comply with a lower smoke emissions threshold as the authorities announce plans to tighten regulations to protect air quality.
NEA had previously announced in 2018 a similar requirement banning old local motorcycles from Singapore's roads from July 2028, as these older motorcycles generally cause more pollution than motorcycles complying with the newer Euro emissions standards.“Foreign motorcyclists entering Singapore are required to use motorcycles registered on or after Jul 1, 2003, that also comply with Singapore’s in-use emission standards.
If a foreign commercial diesel vehicle is found with smoke emissions of 60 HSU or more, the vehicle will be turned back at Singapore’s land checkpoints and not be allowed to enter the country. In the six months prior to rollout - Oct 1, 2025 to Mar 31, 2026 - NEA will issue advisories to such vehicles entering Singapore to remind them of the new threshold and implementation date.
