Singapore's weather plays by its own rules. One moment the sky is clear; twenty minutes later you're crawling along the CTE in a downpour with visibility down to a few car lengths. For learner drivers and newly licensed drivers alike, heavy rain is one of the most stressful conditions you'll face on the road — and it catches many people off guard because most of our driving lessons happen in dry weather.
Here are the most common wet weather driving mistakes made on Singapore roads, and what you should do instead.
1. Not Reducing Speed Early Enough
Many drivers only slow down once they can barely see ahead. By then, it's already too late to react safely. Wet roads increase your braking distance significantly — sometimes by more than double. The moment rain begins to fall heavily, ease off the accelerator and increase your following distance to at least three seconds behind the vehicle in front. On expressways, four seconds is safer.
2. Leaving Headlights Off
Under the Road Traffic Act, you are required to switch on your headlights whenever visibility is poor — this includes heavy rain, not just night-time driving. Yet many drivers forget, or assume daytime running lights (DRLs) are sufficient. DRLs do not illuminate your tail lights, meaning vehicles behind you may not see you clearly in a downpour. Always switch on your full headlights when it rains heavily.
3. Braking Hard in Standing Water
Puddles and standing water are common along Singapore roads, especially at the edges of older roads and near canal crossings. Driving through standing water at speed can cause aquaplaning — where your tyres lose contact with the road surface entirely. If you feel your steering go light, do not brake hard or turn suddenly. Ease off the accelerator gently and hold the wheel steady until your tyres regain grip.
4. Overspeeding in the Left Lane Near Drains
The leftmost lane on many Singapore roads runs close to roadside drains and kerbs where water pools fastest. Learner drivers often stick to the left lane out of habit, which is fine in dry conditions — but in heavy rain, that lane can behave like a shallow river. Be prepared to check if it's safe to shift one lane right during very heavy rain.
5. Forgetting to Check Wiper Condition
Wipers deteriorate quickly in Singapore's heat and UV exposure. Worn wiper blades leave streaks across your windscreen, creating dangerous glare and reducing visibility exactly when you need it most. Replace your wiper blades every six to twelve months, and always test them before a long drive — do not wait until you're already on the road in a storm.
6. Following a Large Vehicle Too Closely
Trucks, buses and lorries throw up enormous spray. Following too closely behind them in the rain effectively blinds you. Hang back further than usual so you maintain a clear line of sight, and avoid lane changes immediately behind heavy vehicles in wet conditions.
7. Neglecting Tyre Tread Depth
Singapore's legal minimum tyre tread depth is 1.6mm, but safety experts recommend replacing tyres at 3mm. Worn tyres cannot channel water away efficiently, dramatically increasing aquaplaning risk. If your tyres are borderline, wet weather will expose it immediately.
Build Confidence Before You Face Real Rain
One of the best things you can do as a learner is to mentally rehearse routes before you drive them, so that when rain hits, you're not also trying to navigate unfamiliar roads. SteerClear, the Singapore app for practising real driving test routes with live scoring, helps you learn Singapore roads thoroughly — so bad weather is one less thing on your mind.
- Slow down early and increase following distance
- Switch on headlights — not just DRLs — in heavy rain
- Never brake hard in standing water
- Check wiper blades every six to twelve months
- Keep well back from large vehicles spraying water
- Monitor your tyre tread depth regularly
Singapore rain is unpredictable, but your response to it doesn't have to be. Build these habits early, and wet weather driving will become something you handle calmly rather than fear.
