Singapore imposes heavy fines for infractions that might be overlooked elsewhere, so it is important to keep a few basic rules in mind:
- Do not eat or drink on MRT trains, buses, or inside stations.
- The import of most chewing gum is prohibited, though there are approved exceptions for certain dental or medicinal varieties.
- Do not litter or spit; smoke only in designated areas.
- Cross the street only at marked crossings and in accordance with traffic signals.
- E-cigarettes (vapes) are completely banned, including possession.
Note: Declare goods exceeding duty-free allowances (such as alcohol or tobacco) upon entry; carrying undeclared tobacco can result in heavy fines.
