[2026 Update] 15 Things You Must NOT Do in Singapore: Essential Travel Warnings for Visitors

10/12/2025

Singapore is known for being one of the cleanest and safest countries in the world.
However、this safety is supported by extremely strict laws and regulations, many of which differ greatly from those in Japan and other countries.

Some actions that seem harmless to foreigners can result in heavy fines or even arrest in Singapore.
To ensure a safe and trouble-free trip, here are 15 things you must avoid during your stay.

1. Eating or drinking inside MRT trains

Eating and drinking are strictly prohibited inside MRT trains.
Even taking a sip of water can result in a fine of up to S$500.

2. Bringing or selling chewing gum

Chewing gum is essentially banned in Singapore.
Importing, selling, or bringing it into the country may lead to complications.
Littering used gum can result in fines of S$1,000 or more.

3. Smoking outside designated areas

Smoking is allowed only in official smoking areas.
Smoking while walking or near building entrances is illegal and can result in fines of up to S$1,000.

4. Possessing or using e-cigarettes (vapes)

E-cigarettes are fully banned in Singapore.
Possession, usage, or bringing them into the country can lead to fines of S$2,000 even for first-time visitors.

5. Littering, even small items

Singapore enforces littering laws very strictly.
A small piece of trash or cigarette butt can lead to fines ranging from S$300 to S$1,000.

6. Jaywalking (crossing roads outside designated crossings)

Crossing streets outside of pedestrian crossings is illegal.
Jaywalking can result in a fine of up to S$1,000.

7. Causing disturbances in public (shouting, fighting, aggressive behavior)

Public disturbances—especially involving aggression or intoxication—can lead to fines or even arrest.
Singapore maintains strict public order standards.

8. Not flushing public toilets

Leaving a toilet unflushed after use can result in fines up to S$150.
This rule reflects Singapore’s strong emphasis on cleanliness.

9. Repeat offenses leading to “Corrective Work Order”

Repeat offenders of smoking or littering may be sentenced to the Corrective Work Order (CWO).
This involves wearing a bright vest and cleaning public areas in front of the public—a very humiliating penalty.

10. Feeding animals such as monkeys, otters, or pigeons

Feeding wildlife is strictly prohibited to protect ecosystems.
Violations may result in fines.

11. Causing trouble at MRT stations (shouting, throwing items, refusing instructions)

Trouble at transport hubs is taken very seriously.
Incidents may lead to immediate police involvement.

12. Engaging with illegal street vendors or unauthorized fundraisers

Some illegal vendors operate without permits, and tourists can be unknowingly pulled into scams.
Avoid all unlicensed street sales and suspicious donation requests.

13. Drinking alcohol in restricted public areas

Certain neighborhoods—such as Little India—have nighttime alcohol restrictions.
Drinking in prohibited areas can result in penalties.

14. No-show or last-minute cancellation at restaurants

Singapore has a strong reservation culture.
A no-show may lead to cancellation fees or being blacklisted by the restaurant.

15. Excessive public displays of affection

Light contact such as hugs or quick kisses is acceptable, but excessive displays of affection may be considered inappropriate in public spaces.
