A dry windscreen can hide a lot. Then the rain hits on the school run, the motorway or a dark suburban street, and suddenly every smear, worn tyre groove and weak headlight matters. This rain ready car maintenance guide focuses on the simple checks that give you a clearer view, more control and fewer surprises when wet weather arrives.
Rain Ready Car Maintenance Guide: Start With Visibility
Rain changes how quickly you can spot hazards. Spray from trucks, glare from oncoming headlights and water sitting on the windscreen can turn an ordinary drive into a stressful one within seconds. Your first priority is making sure you can see clearly in every direction.
Replace wiper blades that streak, skip or chatter
Wiper blades do more than clear water. They help you identify brake lights, lane markings, pedestrians and cars pulling out of side streets. If your blades leave streaks, miss sections of glass, judder across the screen or make a chattering sound, they are no longer doing their job properly.
Check the rubber edge for splits, hard patches and loose sections. Australian heat can dry and damage rubber long before the next big downpour exposes the problem. Cleaning the blade with a damp cloth may remove road grime, but it will not restore worn rubber.
Replacing blades is a straightforward DIY job when you have the right fit for your vehicle. Model-matched front wiper kits remove the guesswork around blade length and connector type, so you can get back to clear, streak-free wiping without booking a workshop visit. ClearView Wiper makes this easier with a vehicle search tool and easy-install multi-adaptor blades designed for everyday drivers.
Do not forget the rear wiper if your hatch, SUV or wagon has one. Rear visibility is especially useful when reversing out of a driveway or checking traffic in heavy spray.
Top up windscreen washer fluid
Wipers alone cannot clear mud, salt spray, insects or oily film from the windscreen. Check the washer reservoir under the bonnet and top it up with suitable windscreen washer fluid. Plain water can work in a pinch, but a proper washer solution is better at cutting through road grime.
Test the spray nozzles before you need them. If one is blocked or aimed poorly, you may get a clear patch on one side and a dirty smear directly in your line of sight. Use the washers briefly to confirm that fluid reaches the glass and the wipers clear it cleanly.
Check every exterior light
Wet roads reflect light, and grey skies can make cars harder to see even in the middle of the day. Walk around the vehicle with the headlights, tail-lights, brake lights, indicators and hazard lights switched on. Ask someone to press the brake pedal, or reverse near a reflective surface to check the brake lights yourself.
Replace failed globes promptly and wipe away dirt from the lenses. Cloudy or yellowed headlight lenses can reduce useful light output, particularly on unlit roads. If your headlights look dim, check whether the lenses need restoration or whether the globes and electrical system need professional attention.
Tyres Are Your Grip in the Rain
Your tyres are the only part of the car touching the road. In wet conditions, their tread channels water away from the contact patch so the rubber can grip the surface. Worn tyres struggle to do this, increasing the chance of longer stopping distances and aquaplaning.
Look beyond the legal minimum
Australian tyres must have at least 1.5 mm of tread across the central area, but waiting until that point is not a good wet-weather plan. Grip on standing water can decline well before a tyre reaches the legal limit. If the tread looks shallow, the wear indicators are nearly level with the tread, or the tyre has uneven wear, arrange an inspection and consider replacement.
Check for cuts, bulges, embedded objects and cracking around the sidewalls. A tyre can have plenty of tread and still be unsafe if it is damaged or aged.
Set pressures when the tyres are cold
Under-inflated tyres can feel vague, wear faster and handle poorly in the wet. Over-inflated tyres can also reduce the tyre’s effective contact with the road. Use the pressure listed on your vehicle’s tyre placard, usually inside the driver’s door opening or in the owner’s manual, rather than relying on the number printed on the tyre sidewall.
Check pressures before a long drive and at least monthly. Include the spare tyre if your vehicle has one. A flat spare is no help when you are stranded on a rainy roadside.
Make Sure Braking Feels Predictable
Rain does not usually cause brake problems, but it exposes them. Water reduces tyre grip, meaning the same brakes need more distance to bring the car to a stop. If your brakes already feel soft, pull to one side, squeal constantly or shudder through the pedal, do not put off an inspection.
Pay attention to warning lights on the dashboard, including brake and ABS warnings. These systems are designed to help maintain control under hard braking, so a warning light deserves prompt professional diagnosis.
After driving through a deep puddle, brake gently when it is safe to do so. This can help dry the brake discs and restore normal feel. Never drive through floodwater if you cannot judge its depth, current or road condition. It only takes a small amount of moving water to create a serious risk, and water can damage the engine, electrics and cabin.
Prepare the Car for Sudden Weather Changes
A few small checks can make a wet-weather drive much less stressful. Make sure the demister clears the front and rear glass quickly. If the inside of the windscreen fogs often, clean the glass thoroughly and check that the air-conditioning system is operating, as it helps remove moisture from the cabin air.
Check that door and boot seals are intact, particularly if you have noticed damp carpet, a musty smell or water collecting in the spare-wheel well. Clear leaves and debris from the base of the windscreen, around drainage channels and from the area near the bonnet. Blocked drains can allow water to overflow where it should not.
Keep your fuel level sensible before a forecast downpour or regional trip. Traffic disruptions, detours and road closures can add unexpected kilometres. It is also worth carrying a charged mobile, torch, basic first-aid kit and a dry cloth for cleaning the inside of the windscreen if needed.
Adjust Your Driving, Not Just Your Car
Even a well-maintained vehicle needs a different approach in the rain. Slow down before corners, leave more room behind the vehicle ahead and avoid sudden steering, braking or acceleration. The first rain after a dry spell can be particularly slippery because oil and residue rise to the road surface.
If the car begins to aquaplane, ease off the accelerator smoothly and keep the steering pointed where you want to go. Avoid stamping on the brakes or making sharp steering corrections. Your tyres need a moment to regain contact with the road.
Use headlights whenever rain reduces visibility, even during daylight. Low-beam headlights help other drivers see you without creating unnecessary glare. If conditions are severe enough that you cannot see clearly beyond a short distance, find a safe place to stop rather than trying to push through.
Make the Checks Before the Clouds Build
Wet-weather safety is rarely about one big repair. It comes down to a clear windscreen, tyres with real tread, responsive brakes and lights that let others see you. Take ten minutes before the next rainy week to check these essentials. A small maintenance job in the driveway is far easier than driving blind when the weather turns.
