Use main roads wherever you can, as they are less likely to be flooded. Have an alternative route in mind in case of road closures, accidents or floods.
Regularly check that your tyres have the recommended legal tyre tread depth of at least 1.6mm, across the central three-quarters of each tyre around its entire circumference, to ensure you obtain sufficient grip on the roads.
If the weather is particularly wet, it is wise to ensure you have extra grip for safety. If using summer or all-season tyres, at least 3mm is recommended; for winter tyres, at least 4mm.
Ensure you can both clearly see and be seen. Ensure your windscreen wipers – both front and rear – are fully functional. If they squeak as they wipe, leave streaks or don’t clear the glass in a single swipe, they may need replacing.
Make sure that your windscreen wipers are turned off before starting the ignition, to preserve the blades and lessen the chance of a blown motor fuse if they are exposed to frost.
When driving in the rain, you will be using your lights, heater and wipers more than normal, which will reduce your fuel economy. Traffic will also be slower-moving and accidents more likely, which could mean that you use more fuel than normal. Ensure you have plenty in the tank for your journey to allow for these conditions.
Ensure all your headlights, taillights, sidelights, brake lights and indictors are working, so you can signal clearly and be seen in the rain. If visibility is reduced you will have to utilise dipped headlights, so don’t forget to check those as well!
It’s important to reduce your speed in wet weather to leave more space between vehicles, giving more leeway if something unexpected happens and to reduce the likelihood of hydroplaning.
When the roads are slippery, the Highway Code observes stopping distances at least double. Staying at least four seconds from moving traffic ahead is therefore wise to ensure you have longer to react to a hazard.
Watch the road closely in case spray from other vehicles reduces your visibility suddenly. Consider others too and avoid driving too quickly through puddles near to cyclists or pedestrians.
Stay in control to avoiding having to brake or accelerate harshly braking and carry out manoeuvres very slowly and with extra care.
Pedestrians, bikes, motorbikes and horses are harder to spot in the wet, so look out for them closely. Also watch carefully for signs warning of hazards or temporary lower speed limits.
Keep your headlights on dipped beam so that other drivers can see you easily but not be dazzled. If visibility is very low (less than 100m) then The Highway Code states you should use your full beam headlights and you can also switch on front or rear fog lights. However, if visibility improves beyond this you must switch them off, as they can mask your brake lights and dazzle drivers behind you, so keep aware of changing conditions.
If your start to lose some control of your car due to wet weather, don’t instantly brake, as this will affect the car’s balance.
Instead, should your tyres begin to lose traction, ease off the accelerator and allow the speed to decrease naturally until you feel back in full control.
Similarly, if you find your steering becoming unresponsive as the rain prevents your tyres from gripping, reduce acceleration and gradually slow down until you can steer properly again.
If you must drive through a puddle, use the highest part of the road, judging by the edge of the kerb. Avoid driving through if it looks more than 10cm deep, as the air intake in many vehicles is low down at the front and even a small amount of water in the engine can cause damage.
Watch out for objects that may cause damage to your wheels, tyres or suspension, so you can avoid them and use a safe path across. Drive through slowly but steadily in a low gear and with engine revs up to maintain your momentum.
Once you're safely through the water, test your brakes as soon as you can.
Be particularly careful with floods on bends. If you can't see where you're going to come out of the water, think twice about starting to drive into it.
If the water is clearly too deep for your car, find another route. Don't gamble driving down flooded roads: it only takes 1ft of water to float a car. Furthermore, if you damage your engine by driving through water and a new one needs to be fitted, your insurance policy may not cover the bill.
Driving through water can cause hydroplaning, as your tyres lose contact with the road. If your steering suddenly feels light, take your foot off the accelerator, hold the wheel lightly and allow your speed to reduce until your tyres regain their grip and you feel in control again.
Do not brake until you’ve regained control. At that point it’s a good idea to gently brush your brake pedal to create some friction and heat – and therefore evaporate off any outstanding moisture.
Wet weather causes more breakdowns as damp conditions increase issues with electrics and engines.
Should your car break down, pull over to a safe visible place, turn on the hazard lights, and wait for help to arrive. If your engine cuts out after you have had to navigate deep water, don’t try and restart it, as engine damage may occur. Instead, stop and call for professional assistance.
Keep the bonnet shut while waiting, as the engine will be more difficult to start if the electrics are soaked with rain.

With the challenges of driving in bad weather, if you are hiring a car and are likely to face them, you should consider car hire excess insurance to cover you if you have an accident whilst driving.
While many car hire companies offer cover, taking it out with them could be far more expensive (and less comprehensive) than cover provided by an insurance provider - such as insurance4carhire.com. Find out more about our policies and what car hire excess insurance is.
