Be honest- do you slow down much while driving in the rain? Do you change your driving style at all?
Do you leave extra room for braking, even if it's not raining that hard?
How dangerous is driving in the rain?
According to Highways England, people are 30 times more likely to be killed or injured on the roads when it is raining, rather than in snow or icy conditions.
Apparently, we automatically adjust our expectations and driving style in snow, fog or ice, but not so much in rain. A few years ago, Highways England launched a “Rain Kills” warning to drivers in the hope to reduce these sad statistics.
Most of you reading this will already have your driving licence (and probably had it for a while!) We've all driven in heavy rain and (hopefully!) stayed unscathed.
But it never hurts to have a refresher on driving in the rain safety tips- ESPECIALLY if you are going to be driving a bigger vehicle than usual (you know… like a motorhome…)
How much slower should you drive in the rain?
Even doing the speed limit can be dangerous in rain, especially very heavy rain. The key thing is how much space you leave between you and the vehicle in front. Stopping distances are increased substantially (over twice as long) when the road surface is wet- that's assuming you can stop and the car doesn't just aquaplane if you brake too hard.
There is no hard or fast rule saying how much slower you should drive in the rain. Some countries, like France, have two speed limits on their major motorways- one for normal weather and one for rainy conditions. (130km vs 110km/ hour)
Driving in the rain safety tips- before you set off
The first step to staying safe on the roadways is to understand and plan for upcoming weather conditions. Using a weather-focused website helps you forecast weather conditions for your journey, allowing you to plan ahead.
For example, if you know in advance you will be driving in heavy rain, you can make sure to:
- have your windshield wipers replaced with new blades
- have your windshield wiper fluid upgraded to one which naturally aids your windshield in repelling water.
- Check tyres for adequate tread (and find out if you need winter tyres fitted)
- Check tyre pressure is correct
- Ensure all vehicle lights are working: headlights, brake lights, indicators, fog lights and hazards
(We all know we should be doing that before every trip anyway… right? Don't rely on a clever vehicle system to tell you when a bulb is out- go check them manually before your next road trip.)
How to Stay Safe When Driving in Heavy Rain
I asked Richard Jackson, from WorldWeatherOnline to give us his top tips for driving safely in rain.
It can be hard work driving in heavy rain, especially if you are travelling in a new location. Unknown roadways, sudden curves, reduced field of vision and more can be a recipe for disaster for those unprepared and not driving sensibly for the weather.
There are several safety precautions which should be observed when driving in the rain. These are things you can do to ensure you and your passenger’s safety when driving in heavy rains during daytime or at night.
In the event that you encounter bad weather while driving, remember these heavy rain safety tips:
- Use your headlights and your wipers. Not only will using these help you to see better but having your headlights on will make you more visible to other drivers.
- Drive more slowly than usual. No matter what the speed limit sign says, slow down until you are comfortable. This will also keep you from hydroplaning on standing water you may come across.
- Leave lots of braking room between you and the car in front of you. When we were first learning to drive, we were always aware of the “one car length” rule. As we get more confident, we often let this lapse. During rain, it is recommended to leave extra space.
- Do not slam on your brakes. This is another way to skid across the road, or hydroplane. You can lose control of your car in this situation and end up in an accident.
- Try and avoid standing water– this is the easiest way to avoid aquaplaning. Try and follow the ‘tracks' of the vehicle ahead of you. (Just out of interest- hydroplaning & aquaplaning are exactly the same thing- skidding across the top of water in a terrifying and not-very-controllable way.)
- If you do hydroplane, react calmly. Do not slam on your brakes or yank the wheel. Instead, come off the accelerator and try to carefully yet firmly keep your car headed in the direction it is supposed to go.
- Use built-in ventilation options to de-fog your windows. If you cannot see, pull over to avoid an accident.
- Engage your brain. We often behave subconsciously, especially in areas where we are comfortable. If you are entering risky weather, take care to be alert of your surroundings and aware of the choices you make while driving.
- Do not use cruise control. If you accidentally hydroplane, cruise control will make the car go faster. It is best to be in control of as much of the car as you can during rainy weather
- Take extra precautions when merging. Your visibility will be more limited, so make use of all your mirrors and be sure to check over your shoulder. If someone is in the car with you, they can help look for cars. Clearly signal before you move over.
- Check and check AGAIN for motorcyclists. They are easily hidden by rain spray. Make sure you indicate clearly and wait a couple of seconds before you change lanes.
Staying Safe While Driving in the Rain at Night
Here are some extra tips to help you stay safe if you are driving in heavy rain during the night:
- Give large trucks or buses extra space. If you follow them too closely, you will get caught in the wake of their tyres. All the water splashing up off the road will greatly decrease your visibility.
- Be aware that roads will have a glare at night and may affect your visibility. Slow down when approaching oncoming vehicles, as the glare from their lights will also decrease your visibility.
- If there's a storm with lightning, keep in mind that you will feel temporarily blinded by these lights and adjust your speed accordingly.
- Never drive beyond where you can see. A curve or a hidden puddle may spell disaster, so always be looking ahead of where you are.
Renting a Vehicle for Your Travels
Thinking of renting a car or motorhome for your next road trip? It's a brilliant idea for a holiday (here are 12 PERFECT road trip destination ideas in Europe), but be sure to check the condition of the vehicle when you collect it.
If you will be driving in winter (and not somewhere sunny like these 7 warmest places in mainland Spain!) be sure that your vehicle comes with appropriate winter tyres. If you are in a car, make sure you know if you have traction control or not.
Even in summer, if heavy rains are forecast, skip the sports car and go with something more practical. Also be sure to discuss with the rental place the condition of wiper blades, headlights and other attributes that may aid you in navigating safely through heavy downpours.
No matter whether you're renting a vehicle or taking your own, I hope these driving tips have helped you feel more confident to drive in rainy conditions.
If you remember nothing else, remember to slow down and turn your lights on. If in doubt, and if the rain is really heavy, pull over somewhere safe and wait it out. There's no shame in being cautious if it helps prevent an accident.
If you aren't going to be using your motorhome or camper during winter, please remember to prepare it for winter storage to avoid damage which insurance companies may not cover. See our motorhome winter storage checklist here.
