One of the most commonly enforced — and most commonly misunderstood — rules for drivers crossing from Singapore into Johor Bahru. Here's exactly what it requires.
Under Singapore Customs regulations, every Singapore-registered vehicle departing Singapore by land (via Woodlands Causeway or Tuas Second Link) must have its fuel tank at least three-quarters (75%) full at the point of exit. This is checked at the Singapore checkpoint before you cross — not on the Malaysian side.
The rule applies specifically to Singapore-registered cars and motorcycles. It does not apply to Malaysia-registered or other foreign-registered vehicles entering Singapore. The intent is to prevent Singapore-registered vehicles from crossing over specifically to exploit Malaysia's cheaper, subsidized fuel prices without contributing a comparable amount of fuel duty at home.
If your tank is checked and found below the three-quarter mark, you'll face a composition fine of up to S$500, and you'll be required to turn back into Singapore to top up before being permitted to exit again. This can cost significant time on top of the fine, especially during peak hours — it's an entirely avoidable delay.
No. Malaysia's RON95 petrol is a subsidized fuel reserved exclusively for Malaysian-registered vehicles. Foreign-registered vehicles — including Singapore-registered cars — are only legally permitted to pump unsubsidized RON97 or RON100. Many stations near the checkpoint have separate pumps or enforcement checks specifically for foreign plates.
