Driving on Wet Roads: Your December Holiday Safety Guide
Woza Dezember, the summer holidays come with a festive vibe—and loads of rainfall. Driving on wet roads takes extra skills and vigilance. Did you know that wet roads and poor visibility are the cause of 27% of South Africa’s road fatalities¹? Knowing how to handle these conditions could save your life.
You may be travelling roads you know or exploring a new destination these school holidays. Either way, Matrix is right by your side with practical advice to help you arrive safely.
Why Wet Roads Are More Dangerous
Wet conditions transform even familiar routes into hazards. Your tyres may only have half as much grip on wet surfaces as on dry roads, and braking distance increases by up to 50% on wet roads (compared to dry conditions) according to the Automobile Association and Ominsurecoty.
December is particularly challenging. Most of South Africa receives summer rainfall from November to March, with December having the second-highest monthly average rainfall (SA Places Online). That means you’re likely to encounter wet conditions during your holiday travels.
Essential Tips for Driving on Wet Roads
Slow Down and Increase Following Distance
Speed limits are designed for ideal conditions. When it’s wet, you need to adjust.
- Reduce speed by at least 20% below the speed limit in heavy rain.
- Keep a 4-6 second following distance between you and the vehicle ahead.
This gives you critical reaction time if something unexpected happens. Remember, it’s not just about your driving skills. It’s about physics.
Switch On Your Headlights
Visibility matters for everyone on the road. Switch on your headlights, especially when natural light is low.
This helps other drivers see you, reducing collision risks.
Use low-beam headlights or fog lights in heavy rain. Avoid high beams, as they reflect off rain droplets and create dangerous glare.
Avoid Sudden Movements
Never use the brakes suddenly because this may cause the car to skid. Instead, do one thing at a time. Brake first, then steer, then accelerate. This prevents overloading your tyres and helps maintain traction.
Never Drive Through Flooded Areas
If you can’t judge the depth of water, find another route. More than 60% of flash flood fatalities in South Africa involve vehicles². Water can damage your engine and sweep your vehicle away. It’s simply not worth the risk.
Vehicle Checks To Do Before You Leave
These simple checks take minutes but make a massive difference in wet-weather performance.
- Check your tyre tread depth. You need at least 3mm for a proper grip on wet roads.
- Test your windscreen wipers (front and back). Replace them if they streak.
- Ensure all lights work properly, including brake lights and indicators.
- Verify your brakes are in good condition.
- Check weather forecasts for your route and destination.
- Share your travel plans with someone.
- If conditions deteriorate significantly, pull over safely and wait it out. Arriving late is better than not arriving at all.
