Heavy rain can make an ordinary drive much more difficult. Roads become slippery, visibility drops, stopping distances increase and standing water can cause a vehicle to lose grip unexpectedly.
The safest approach is to slow down, increase your following distance, use your headlights when visibility is reduced and avoid driving through deep or fast-moving water. If conditions become too dangerous, finding a safe place to stop is often the best decision.
Melbourne can experience sudden heavy rain, particularly during changing weather conditions. Whether you’re commuting through the suburbs, travelling on a freeway or driving on country roads, knowing how to handle wet conditions can help you stay in control.
Why Is Driving in Heavy Rain More Dangerous?
Rain affects several parts of driving at the same time.
Your tyres have less grip on a wet road, visibility can become poor and water can collect in areas where drainage is limited. Other drivers may also struggle to see clearly or may brake suddenly.
Heavy rain can also hide potholes, road debris and damaged sections of the road.
The combination means you may have less time to react when something unexpected happens.
That’s why wet-weather driving isn’t simply about turning on the wipers. You need to adjust your speed, following distance and driving style to match the conditions.
How Should You Drive in Heavy Rain?
Slow down, leave more space between vehicles and make every movement smoother.
Avoid sudden braking, sharp steering or aggressive acceleration. Your tyres need as much contact with the road as possible, and smooth inputs help maintain that grip.
You should also keep both hands properly positioned on the steering wheel and stay focused on the road.
If visibility becomes extremely poor, don’t feel pressured to continue just because you have somewhere to be. Find a safe location to stop and wait for conditions to improve.
Why Should You Reduce Your Speed in Wet Conditions?
Wet roads can increase the distance your vehicle needs to stop.
At higher speeds, you also have less time to react to standing water, other vehicles or obstacles.
Reducing your speed gives you more time to respond and can help your tyres maintain better contact with the road.
There’s no single speed that is appropriate for every rainy situation. A speed that feels comfortable on a lightly wet suburban road may be too fast during a severe downpour.
Drive to the conditions rather than simply driving at the posted speed limit.
How Much Following Distance Should You Leave?
Increase the gap between your vehicle and the one in front.
If the vehicle ahead brakes suddenly, a larger gap gives you more time and space to respond.
This is particularly important on freeways and major roads where vehicles are travelling at higher speeds.
Avoid sitting close behind trucks and buses as well. Large vehicles can throw significant amounts of spray onto your windscreen, temporarily reducing visibility.
If you can’t clearly see the road ahead, you’re too close or travelling too fast for the conditions.
What Is Aquaplaning?
Aquaplaning, also called hydroplaning, occurs when a layer of water builds between your tyres and the road surface.
When this happens, the tyres can temporarily lose contact with the road.
You may suddenly feel the steering become light or less responsive. The vehicle may also begin to drift.
Aquaplaning can happen even when you’re travelling within the normal speed range, particularly where there is significant standing water or worn tyre tread.
What Should You Do If Your Car Starts Aquaplaning?
Stay calm and avoid sudden steering or braking.
Ease off the accelerator and keep the steering wheel pointed in the direction you want the vehicle to travel.
Don’t make sharp steering movements to try to correct the vehicle immediately.
As the tyres regain contact with the road, normal steering control should return.
The best way to deal with aquaplaning is to reduce the likelihood of it happening in the first place. Slow down when you see standing water and make sure your tyres are in good condition.
Why Are Tyres So Important in Wet Weather?
Your tyres are the only part of your vehicle directly contacting the road.
Their tread helps move water away from the contact area, allowing the tyre to maintain grip.
Worn tyres can have less ability to clear water effectively, increasing the risk of losing traction in wet conditions.
Before driving regularly in heavy rain, check your tyres for:
- Adequate tread
- Correct inflation pressure
- Uneven wear
- Cracks or visible damage
- Objects embedded in the tread
If you’re unsure about your tyres, have them inspected by a qualified tyre professional.
Does Tyre Pressure Affect Wet-Weather Driving?
Yes.
Incorrect tyre pressure can affect handling, braking and overall tyre performance.
Both over-inflation and under-inflation can affect the way a tyre contacts the road.
Check your vehicle manufacturer’s recommended tyre pressures rather than relying on the number printed on the tyre itself. The manufacturer’s recommendation is usually found on a label inside the driver’s door area or in the owner’s manual.
Check pressures when the tyres are cold for the most useful reading.
Should You Use Your Headlights in Heavy Rain?
If rain significantly reduces visibility, using your headlights can help you see the road and make your vehicle more visible to other motorists.
Avoid relying solely on daytime running lights because they may not provide the rear lighting you need in poor visibility.
If conditions are severe enough that you are struggling to see clearly, slow down and consider whether it is safer to stop somewhere appropriate.
Remember that headlights are there to improve visibility, not to compensate for driving too quickly for the conditions.
Should You Use High Beam in Heavy Rain?
Usually, no.
High beams can reflect off rain and water droplets in the air, creating glare that can actually make it harder to see.
They can also dazzle other drivers.
Use the lighting setting appropriate for the conditions and surrounding traffic. If visibility is poor, reducing your speed is generally more useful than simply using brighter lights.
How Can You Keep Your Windscreen Clear?
Good visibility is essential during heavy rain.
Before driving, make sure your windscreen is clean and your wiper blades are in good condition.
During heavy rain:
- Use the appropriate wiper speed
- Use the demister if the windows begin fogging
- Keep your windscreen washer fluid topped up
- Make sure your headlights and tail lights are clean
- Replace worn or damaged wiper blades
If your wipers leave large areas of water behind or create streaks across the glass, they may need replacing.
Why Do Windscreens Fog Up During Rain?
Rainy weather can create a difference between the temperature and humidity inside and outside the vehicle.
When moisture condenses on the inside of the windscreen, visibility can deteriorate quickly.
Use the vehicle’s demister and air-conditioning system as recommended by the manufacturer.
Don’t attempt to drive while your windscreen is heavily fogged. Take a moment to restore clear visibility before continuing.
What Should You Do When You See Standing Water?
Slow down before reaching the water and avoid it if you can safely do so.
Standing water can be deeper than it appears.
It can also hide potholes, debris or damaged sections of the road.
If you see a large pool of water ahead, don’t suddenly swerve around it without checking surrounding traffic. A sudden lane change can create another hazard.
Assess the situation early and make smooth, controlled decisions.
Is It Safe to Drive Through Floodwater?
Not necessarily.
Even relatively shallow-looking water can be difficult to judge from the driver’s seat. Water depth can change quickly, and moving water can be particularly dangerous.
Floodwater may also contain debris or conceal damage to the road.
Never deliberately drive into deep or fast-moving floodwater simply because another vehicle has managed to pass through.
If a road is flooded or closed, follow official signs and directions and find an alternative route.
What Can Happen If You Drive Through Deep Water?
Driving through deep water can cause serious problems.
Water may enter the engine intake, electrical components or other parts of the vehicle. Depending on the vehicle and depth of the water, this can result in mechanical or electrical damage.
Water can also reduce tyre grip and affect braking.
If your vehicle has been driven through significant floodwater and begins behaving unusually, stop somewhere safe and have it checked.
Don’t assume that everything is fine simply because the engine continues running.
What If Your Vehicle Stalls in Floodwater?
If your vehicle stalls in deep or rising water, do not repeatedly attempt to restart the engine.
Restarting a flooded engine can potentially cause further mechanical damage depending on how much water has entered the engine.
Your immediate priority should be personal safety.
If the vehicle is in rising or moving water, leave the vehicle only when it is safe to do so and follow emergency instructions. Do not put yourself at risk trying to save the car.
If the vehicle is stranded and cannot be safely driven, professional recovery may be required.
How Should You Drive on Wet Freeways?
Freeway driving in heavy rain requires extra concentration because speeds are higher and stopping distances are longer.
Leave plenty of space between your vehicle and others, avoid unnecessary lane changes and keep your speed appropriate for visibility and road conditions.
Watch for spray from trucks and buses.
If visibility suddenly becomes extremely poor, don’t brake sharply in the traffic lane unless necessary. Look for a safe location where you can pull over without creating another hazard.
Should You Use Cruise Control in Heavy Rain?
It’s generally better to avoid cruise control when roads are wet or conditions are poor.
When traction changes unexpectedly, you want full control over the vehicle’s acceleration and speed.
Being able to immediately ease off the accelerator can be useful if your tyres encounter standing water.
Instead, maintain your speed manually and concentrate on the road conditions ahead.
How Should You Brake on Wet Roads?
Brake earlier and more smoothly than you would on a dry road.
Avoid leaving braking until the last moment.
Modern vehicles with ABS are designed to help maintain steering control during hard braking, but ABS doesn’t eliminate the need for a safe following distance.
If you have to brake suddenly, apply firm pressure as appropriate for your vehicle and allow the system to work rather than repeatedly pumping the brake pedal on a vehicle equipped with ABS.
Why Should You Avoid Sudden Steering?
Sudden steering movements can be risky when tyres have reduced grip.
If you suddenly encounter standing water, debris or another hazard, it’s tempting to make a sharp movement to avoid it.
However, aggressive steering can cause the vehicle to become unstable.
Look well ahead and anticipate potential hazards. Smooth steering inputs give your tyres a better chance of maintaining grip.
What Should You Do If Another Driver Is Driving Too Fast?
You can’t control what other motorists do.
If another vehicle is travelling too quickly in heavy rain, don’t try to match its speed.
Maintain a safe speed and leave enough space around your own vehicle.
Be especially careful when another vehicle passes you and creates a large amount of spray.
Your priority is maintaining control of your vehicle, not keeping up with traffic that may be travelling too fast for the conditions.
Are Melbourne Suburban Roads Safe During Heavy Rain?
They can be, but conditions can change quickly.
Suburban roads may have drains, low-lying areas, potholes, painted road markings and intersections where water accumulates.
Be particularly careful near:
- Underpasses
- Bridges
- Low-lying roads
- Areas with poor drainage
- Roadworks
- Tree-covered roads
- Intersections with standing water
Don’t assume a familiar route will behave exactly the same way during a major downpour.
What Should You Check Before Driving in Heavy Rain?
A quick vehicle check can help you prepare.
Before setting off, check:
- Tyre condition and pressure
- Windscreen wipers
- Windscreen washer fluid
- Headlights and tail lights
- Brake condition
- Windscreen visibility
- Demister operation
If your tyres are badly worn, your wipers aren’t clearing the windscreen or your lights aren’t working properly, address the issue before driving in severe weather where possible.
What If Your Car Breaks Down During Heavy Rain?
If your vehicle breaks down in wet conditions, get yourself to a safe position first.
Turn on your hazard lights and, if possible, move the vehicle away from moving traffic.
Avoid standing directly beside the vehicle on a busy road.
If the vehicle cannot be driven safely, arrange roadside assistance or towing. Tell the operator that you’re dealing with heavy rain and provide your exact location.
If the vehicle is stuck in floodwater, prioritise your safety over the vehicle.
Can Heavy Rain Cause Vehicle Problems?
Yes.
Water can affect several vehicle components, particularly if the vehicle is driven through deep water.
Heavy rain can also expose existing problems with:
- Tyres
- Brakes
- Windscreen wipers
- Electrical systems
- Battery connections
- Belts
- Lights
If warning lights appear, the brakes feel unusual, the engine starts running roughly or the vehicle behaves differently after driving through water, have it checked.
Don’t ignore changes simply because the rain has stopped.
What Are the Biggest Wet-Weather Driving Mistakes?
Some of the most common mistakes are surprisingly simple:
- Driving too fast for the conditions
- Following too closely
- Using worn tyres
- Ignoring standing water
- Making sudden steering movements
- Braking too late
- Driving with poor visibility
- Using cruise control in heavy rain
- Driving through floodwater
- Continuing when conditions have become unsafe
The key lesson is that heavy rain requires a different driving approach.
You don’t need to panic. You simply need to slow down, create more space and give yourself more time to react.
Give Yourself More Time When the Weather Turns Bad
Heavy rain doesn’t necessarily mean you have to stop driving, but it does mean you need to adjust your approach.
Slow down, increase your following distance, keep your windscreen clear and avoid standing water wherever possible. Pay attention to your tyres and don’t ignore warning signs from your vehicle.
If conditions become severe enough that you can’t maintain a clear view of the road or control the vehicle comfortably, there’s nothing wrong with finding a safe place to stop.
Getting to your destination a little later is far better than taking unnecessary risks on a wet Melbourne road.
