As South Africa transitions into spring and prepares for the inevitable heatwaves of summer, drivers must gear up for the challenges that come with warmer weather. Eugene Herbert, CEO of MasterDrive, emphasizes the importance of defensive driving as the most effective way to navigate the risks associated with summer driving.
Data from the United States Department of Transportation highlights the heightened danger on roads during the summer months. In the northern hemisphere, from June to August, more than 30% of fatal road accidents occur. While South Africa’s summer season differs, the risks remain consistent, especially with an increase in road users, congestion, and the added element of unpredictable weather.
Why Summer Driving Is More Dangerous
The uptick in road fatalities during summer is driven by several factors:
- Increased road traffic: Summer brings more drivers onto the roads as people take vacations and enjoy outdoor activities.
- Congestion: With more cars on the road, the likelihood of accidents rises, particularly in high-traffic areas or during holiday periods.
- More intoxicated drivers: As social activities ramp up, so does the risk of encountering drivers under the influence of alcohol.
- Vehicle stress: High temperatures can affect vehicle performance, increasing the chances of mechanical failure, such as tyre blowouts or overheating engines.
According to Herbert, regular vehicle maintenance and adopting safe driving habits are essential in reducing the risks associated with summer driving. Below are his key tips for preparing both your vehicle and yourself for the challenges ahead.
Preparing Your Vehicle for Summer Heat
Vehicle maintenance is paramount when it comes to safe driving in the summer. Ensuring your car is in top condition can help avoid potentially dangerous breakdowns or malfunctions.
- Tyres: Ensure that your tyre tread is no less than 3mm, especially as summer rain can reduce road grip. “Underinflated tyres increase the risk of a blowout,” warns Herbert. Tyre pressure should be checked regularly, and any signs of wear or damage should be addressed immediately.
- Battery: Hot weather places additional strain on your vehicle’s battery. “Temperatures over 25⁰C can shorten battery life. Parking in the shade when possible can help, and it’s worth knowing how to care for your specific battery type,” says Herbert.
- Fluids: Check vital fluids, including engine oil, windscreen washer fluid, and coolant levels. “Coolant is especially important as it prevents overheating, which is a common issue in summer,” adds Herbert.

Preparing Yourself for Summer Driving
As much as vehicle preparation is crucial, so is driver readiness. Hot weather can affect concentration and fatigue levels, both of which are critical for safe driving.
- Sunglasses: Polarised sunglasses can reduce glare, making it easier to see in bright conditions and protecting your eyes from long-term sun damage.
- Hydration: Keep water in your vehicle during heatwaves. Dehydration can impair focus and reaction times, increasing the risk of accidents.
- Fatigue management: Fatigue is a serious concern during long summer drives. Herbert advises, “Make sure to get enough rest before a journey, and take breaks every two hours on long trips. Heat increases fatigue, so be alert to signs of drowsiness.”
Planning Your Route
Proactive route planning can help drivers avoid the worst of summer’s heat and congestion. Check traffic updates and social media for alerts about road conditions and accidents.
- Avoid congestion: If possible, schedule your trips outside of peak hours to dodge traffic jams. “Congested roads and extreme heat can exacerbate stress and fatigue,” says Herbert.
- Plan for events: Summer brings with it concerts, sporting events, and holiday traffic. Be prepared for additional pedestrians and drivers at these locations, and adjust your driving style accordingly.
- Air conditioning: If your vehicle doesn’t have air conditioning, consider travelling early in the morning or later in the evening to avoid the highest temperatures.
Staying Alert for Impaired Drivers
Increased socialising during summer means a higher chance of encountering drivers under the influence. “If you spot erratic driving, create distance between your vehicle and theirs,” advises Herbert. Reporting such drivers to the authorities is another important step to ensure everyone’s safety on the road.
Summer driving requires a mix of preparation, vigilance, and defensive driving. By taking these simple but effective steps, South African drivers can reduce the risks associated with driving during the summer months. Ensuring your vehicle is in good condition, planning your routes carefully, and staying alert to the dangers on the road are all essential strategies to keep you and your passengers safe this season.
