Traveling around Singapore till late hours of the night on busy commercial areas is absolutely safe if you are a local. As Singapore was a British colony, communication is not a problem as most locals speak fluent English. People traveling to Singapore for the first time on holiday or business should take time to understand local regulations about littering, public behavior and hygiene as there are stiff fines for offences like smoking in public places, spitting or throwing even small pieces of paper on the sidewalk. To have a memorable stay in this picturesque city and enjoy all the delightful experiences it has on offer, it is best to understand local regulations to be safe rather than sorry about visiting Singapore.
Drugs and punishment
Laws in Singapore are very strict so jaywalking or loitering around smoking and chewing gum is not acceptable. If you are traveling to the city for a short vacation with the family or with young friends and have planned weekend hotel stay in Singapore then it is best to stay away from soliciting drug purchase or sales in any manner. Possession and consumption of drugs in Singapore is punishable by death so stepping out of line with drugs as a tourist is a foolish idea.
Traveling by car
Taxis are relatively inexpensive in Singapore and tourists can travel everywhere in safety if they are absolutely sure about their destination else they are likely to get overpriced. As all local taxis have meters you are safe from negotiating about prices and can expect a fair bill after the ride. If you feel that the cab driver has overcharged then calls up the company to which the driver belongs as all details will be available in the bill itself. To keep costs down take a map with you to find out exact distance to destination and then take assistance of hotel reception to get a fair priced cab.
Traveling during weekends
As there are several Malaysian and Indonesian residents working in Singapore traveling to the city on a weekend by public transport or road is a tiresome exercise. If you are planning a weekend hotel stay in Singapore then avoid traveling during Sunday. It is advisable to drive over during weekdays like Thursday or Friday. Pack plenty of insect repellant and keep away from wooded areas as there are plenty of creepy crawlies in the under-bush that are common in tropical countries.
