The Rule in One Minute
Leaving Singapore by land? Your fuel tank must be at least three-quarters full or you risk a fine, prosecution, and being turned back at the checkpoint. This rule is enforced by Singapore Customs at both Woodlands and Tuas.
What Fuel Types Are Covered?
- Petrol — Always covered.
- Diesel — Included since 1 April 2019. If you drive a diesel car, the same 3/4 rule applies.
- CNG (Compressed Natural Gas) — Also applies. For hybrid petrol/CNG vehicles, both tanks must be at least 3/4 full.
- Electric Vehicles (EVs) — Exempt. No fuel tank = no 3/4 requirement.
Penalties for Non-Compliance
- Fine of up to S$500.
- Possible prosecution for repeat offenders.
- Forced U-turn back to Singapore to refuel.
- Significant trip delay — refueling + rejoining the checkpoint queue.
Quick Self-Check Tips
- Top up before the BKE/AYE fork — there are Shell and Esso stations near the expressway exits.
- Keep your fuel receipt as evidence in case of disputes.
- If your gauge needle hovers near the 3/4 mark, fill up anyway. It's not worth the gamble.
- Diesel drivers: double-check — many forget diesel was added to the rule in 2019.
