Rain is often seen as harmless, but when you’re behind the wheel, it can become a serious hazard. In fact, rain is one of the leading causes of road accidents due to reduced visibility and the risk of hydroplaning. That’s why it’s crucial to take all necessary precautions when driving in bad weather.
Main Risks of Driving in the Rain
The greatest danger is undoubtedly reduced visibility. Heavy rain makes it difficult for drivers to clearly see the road and other users. Humidity inside the car also fogs up the windows, making visibility even worse.
Hydroplaning is another major risk. When your tires can no longer channel water away properly, they lose grip on the road, which can cause you to lose control of the vehicle.
High humidity also increases your braking distance. Wet brake pads and discs significantly reduce braking performance.
Driving in the Rain: Statistics
According to Québec’s auto insurance board (SAAQ) in its 2022 road safety report, 392 people died in road accidents and 1,275 were seriously injured that year. While the exact weather conditions aren’t specified in each case, the report stresses the importance of driving cautiously, especially in the rain.
Safety Tips for Driving in the Rain
Here are the top recommendations from the SAAQ to help you stay safe when driving in rainy weather:
- Maintain a greater following distance than usual.
- Adjust your speed according to road conditions.
- Turn on your low-beam headlights to be more visible.
- If you hydroplane: stay calm, keep your steering wheel straight, and slowly ease off the accelerator.
7 Essentials to Check Before Driving in the Rain
These checks and habits will help keep you safe even in harsh weather conditions:
1. Tires
Check your tires before hitting the road. It’s best to use rain-friendly tires with deep enough grooves to disperse water and prevent hydroplaning. Also check the pressure—if it’s off, your handling could be affected.
2. ADAS System
An Advanced Driver Assistance System (ADAS) includes various technologies that enhance safety in wet conditions, like emergency braking, adaptive cruise control, and lane-keeping assist. Before you drive, ensure your system is calibrated and working properly.
3. Aquapel Treatment
Aquapel rain repellent is applied directly to your windshield and helps water bead and roll off easily, improving your visibility in the rain. It makes a big difference when conditions get rough.
4. Headlights
Your vehicle’s lights are essential for safety. Make sure all your lights are clean and functioning: low beams, high beams, running lights, turn signals, and fog lights. Well-aligned headlights help you see and be seen—badly adjusted ones can blind other drivers or reduce your own visibility.
5. Windshield Wipers
Wipers are crucial for clear vision. Check their condition regularly and replace them at least once a year or as soon as they show signs of wear. Don’t forget to top up your windshield washer fluid before a long trip.
6. Brakes
Brakes are one of your car’s most important safety systems. Rain increases stopping distance, so it’s vital they work properly. Have a professional inspect your brake pads, discs, and fluid regularly.
7. Battery
Your car battery powers key components like headlights, wipers, and the defogging system. Make sure it’s fully charged and in good shape—especially in winter when cold weather can drain its performance.
Conclusion
Driving in the rain comes with challenges, but with a few precautions and vehicle checks, you can greatly reduce your risk on the road. When the weather is really bad, it’s always better to postpone your trip if you can.
FAQ
How should I drive in light rain?
Stick to speed limits and turn on your low beams as soon as it starts to rain to stay visible. Clean your windshield regularly to prevent glare, replace your wipers before the rainy season, and check tire wear and pressure.
What about during heavy rain that reduces visibility?
Keep your low beams on, slow down to 40 km/h (if visibility drops below 50 metres), use your front fog lights if needed, leave more space between you and the vehicle ahead, and avoid hard braking—especially if you don’t have ABS.
Can I use rear fog lights when it’s raining?
Only use rear fog lights when visibility is extremely poor, such as in thick fog, heavy snowstorms, or torrential rain.
What should I do if I hydroplane?
Ease off the accelerator gradually and keep the steering wheel pointed in the direction you want to go. Stay calm and avoid sudden movements.
