Singapore on a US Licence 2026: Keep Left, Carry a 1949 IDP

Most Americans who drive in Singapore are on a short stopover, and the city’s public transport is good enough that a car is optional. If you do rent one, two things matter before anything else: the permit in your bag and the side of the road.

Do you need a permit?

Carry an International Driving Permit with your US licence. Global Affairs Canada says visitors must carry one, and the UK government’s permit table lists the 1949 IDP for Singapore, needed for car hire and for stays longer than 30 days. The US issues the 1949 permit, and the State Department authorises only AAA and AATA to sell it, so get it before you fly. Note that the State Department’s own Singapore page is silent on the licence, so the permit advice comes from the other two governments. If you end up living in Singapore for more than 12 months, you must convert to a Singapore licence. For other trips, the Driving Permit Checker lists each country’s rule.

What the State Department says about the roads

Singapore has a highly developed, well-maintained road and highway network, according to the Department. Two cautions follow. Motorcyclists often ignore lane markings, so check mirrors and blind spots more than you would at home. And laws on traffic rules, vehicle registration and liability in an accident are strictly enforced, with violations that may bring criminal penalties. Closed-circuit cameras monitor all major roads.

Help is easy to reach. The Automobile Association of Singapore provides roadside assistance, and the Land Transport Authority has rescue vehicles on the road at all hours. Public transportation and taxis are abundant, inexpensive and reliable, which is why many visitors skip the car.

Driving on the left

Singapore drives on the left. You sit on the right of the car, roundabouts flow clockwise, and the classic error is drifting into the right lane after a turn. Turns across traffic are now to the right, which is the move that feels like a left turn at home, so slow down and look for oncoming cars. Take a slow first half-hour somewhere quiet before joining the expressways.

Speeds in miles per hour

Expressways are capped at 90 km/h, or 56 mph. A US interstate allows far more, and the lower limit is enforced. In built-up areas the figure is lower still, with 50 km/h (31 mph) the usual town number. If you are looking for the speed limit by road, the Speed Limit Map shows national limits for comparison.

Enforcement and alcohol

Ottawa notes that traffic regulations are strictly enforced, and the UK Foreign Office says police run regular breath tests. The legal limit is 0.08%, the figure most US states use, but the consequences are much heavier: drink-driving can bring up to 10 years in prison. Do not drink if you are driving.

When a car is worth it

With abundant public transport, a car earns its place only for particular plans: a day with young children, heavy luggage, or a trip to an area with limited rail access. If you plan one, rent for a single day, have the permit with you at the counter, and ask how the road-pricing charges on the car are billed. Parking in busy areas is limited, so choose a destination with a car park. For most visitors, a mix of trains, buses and the occasional taxi is cheaper and less stressful than driving on the left in an unfamiliar city.

Whichever you choose, keep the licence and permit on you whenever you drive. Singapore’s enforcement is thorough, and the State Department’s warning about criminal penalties is a reason to leave nothing to chance.

Emergency numbers

In an emergency call 999 for police and 995 for an ambulance or fire. At home you would dial 911 for everything, so put both Singapore numbers in your phone at the rental counter. Our Singapore driving guide has the rest.
