Driving in flash floods Hot spots in Singapore and safety tips



blank space

Recent monsoon downpours caused major flooding in parts of Singapore.

Some motorists were forced to abandon their cars after being stuck in floodwaters that left their vehicles un-roadworthy or seriously damaged.

There are things you can do to minimize the risks. The road safety experts at Budget Direct Insurance have this practical advice:

Good reasons to avoid flood water

  1. If you come across a flood the best advice is to avoid it and to find an alternative route. Even if you’re late for that ‘urgent meeting’ forget it! You’ll regret ruining your car for the sake of a few minutes.
  2. Try to avoid driving through standing water that is more than 15 cms and if it is moving water then it should be no more than 10 cms deep. In short, if it’s ankle deep - avoid it. At this level, water can easily get into your engine bringing you to a halt and causing serious damage to your motor.
  3. A study by the Automobile Association says that most people would endanger their lives by driving through floodwater. And that more than a quarter of respondents would drive through moving floodwater deeper than 30cms which is enough to move a car. Shocking statistics, which show motorists really do underestimate the power of flood water.

Safety advice if you have no alternative

If you really have no alternative and must drive through flood water, here’s what you need to know. 

  1. Enter the water at 1-2mph and then accelerate up to 3-4mph to create a bow wave and to keep water out of the engine.  Even if you’re driving into quite shallow puddles avoid going too fast as the car can start aquaplaning which means the front tires are no longer steering the car and you lose control.
  2. Stay in first gear and keep the revs up to avoid water entering the exhaust pipe. Don’t speed up, though, as this will push water into the engine.
  3. Stay on the crown of the road or the highest part of the road where possible and where water is most likely to be shallower.
  4. When you get out of the water, dry the brakes by using them gently.

What to do if your car aquaplanes

If you hit a build up of water, your car can loose traction. Don’t panic. Resist the temptation to break hard or accelerate suddenly.

“Since hydroplaning is a loss of traction to the front tires sudden braking slows the front tires but locks the rear tires which can cause a spin out. Also sudden acceleration could pull the vehicle straight ahead which could be dangerous if the vehicle is pointed toward the edge of the roadway.” defensivedriving.com

If your car has:

  • Front wheel drive with or without ABS and traction control OR
  • Rear wheel drive with ABS and traction control

Keep your foot lightly on the accelerator, look for the best open space and gently steer in that direction.

If your car has:

Rear wheel drive without ABS and traction control 

Ease off the accelerator and gently steer in the direction of an open space.
