How to Drive Safely in the Rain

Driving in the rain is hard

With Malaysia’s constant heavy thunderstorms and flash floods, we like to offer some crucial advice to help you drive safely in the rain.

Have you ever faced a situation when you’re driving and suddenly there’s a heavy downpour? You’re not alone, as thousands road users have had to confront such a situation on a daily basis, particularly if you’re a Grab or taxi driver.  

Rain can reduce vision

Heavy downpours usually slow traffic to a crawl as people become cautious for all kind of reasons. When heavy rain strikes, visibility will be affected. Therefore, most motorists should engage the brakes earlier in the rain then under normal dry conditions and maintain a greater distance between cars.

The other thing that all motorists should take seriously is the opacity of the car’s windscreen. Your windscreen should be clean, wipers effective and water jets positioned correctly and aimed at the windscreen. When driving in the rain, the wipers are more effective then the headlights. It is also wise to ensure that the wipers are not worn out under Malaysia’s harsh heat and extreme conditions. As for headlights, halogens work better in the rain then Bi-xenon’s or LEDs.

Aquaplanning is dangerous

When driving through flooded areas aquaplaning is a major concern, especially when you hit higher speeds. Aquaplaning is where a wedge of water forms in front of the tyre and lifts it up off the road surface. This is caused by the tread not being able to displace the amount of water present. To recover form aquaplaning, ease gently off your accelerator, have a firm grip of the steering wheel and be sure not to make any sudden steering actions. The car will eventually regain its grip as the water clears.

When braking as the car aquaplanes, again don’t make any sudden steering movements and ease off the accelerator completely. The trick here is to prevent the car from sliding and losing completely out of control.

Avoid flooded areas during heavy rains


If you’re faced with a flood, find an alternative route and avoid it at all costs, especially if the standing water is 15 cm deep or more. If there are no alternatives, park the car on the shoulders of the road and hail a friend or a cab.  

However, if the standing water is shallow, attempt to drive through it is possible; consider this: the best approach is to press lightly on your clutch and add gentle pressure on your accelerator to increase your engine revs. For auto transmissions, do apply pressure on the accelerator without increasing your speed and accelerate slightly but control the speed with your brakes. Do make sure that you drive as slow as possible going through the flood. After passing through, make sure to test the brakes and ensure they’re as dry as possible. Remember if water gets in the exhaust, engine bay or the interior of the car, it could cause a lot of damage, on the car and to your wallet. If engine should take in water, you risk an immediately engine lock and sudden stop. If the water is fast flowing, do not attempt to drive through it, as there is a real danger of your car being swept off the road.
