Weather conditions dramatically impact road safety, route timing, and vehicle range. Whether navigating a summer heatwave, sudden torrential downpours, thick winter fog, or frozen roads, this guide provides essential advice for all drivers, with specialized tips for Electric Vehicle (EV) owners.

Weather & Driving Guide
Safety rules, vehicle performance, and route planning guidelines for extreme weather conditions.
Active Advisory: Extreme Heatwave
With record high temperatures, drivers must take precautions. Pre-cool your cabin while plugged in to save battery range, monitor tyre pressure (which expands in heat), keep hydrated, and check engine coolant before driving.
Active Advisory: Winter Conditions
Freezing temperatures detected. Check your tire tread, use winter washer fluid, keep a scraper handy, and adjust your speed for possible ice.
Active Advisory: Torrential Rain
Heavy rainfall detected. Turn on dipped headlights, increase following distance, and watch out for aquaplaning on highways.
Active Advisory: Low Visibility & Fog
Thick fog detected. Use fog lights only if visibility is below 50m, reduce your speed, and never tailgate.
Navigating Heatwaves & High Temperatures
Driving in high ambient temperatures creates severe thermal stress on both drivers and mechanical systems. Under extreme heat, road asphalt softens, tyre blowout risk increases by up to 50%, and vehicle cabin temperatures can surpass 60°C within 15 minutes of parking.
⚠️ Risk factors: Engine overheating, high fatigue, road melting
⚡
EV Battery Cooling & Charging
Lithium-ion batteries operate less efficiently in high temperatures. Keep your EV plugged in when pre-cooling the cabin (to use grid power instead of battery), and charge during cooler parts of the day if possible. High-speed DC charging may throttle speeds to protect the battery from overheating.
🛞
Tire Pressure & Blowouts
Air expands in heat. Check your tire pressure when tires are cold; driving on over-inflated or under-inflated tires in high heat increases the risk of a blowout.
🌡️
Engine Coolant & Fluids
For combustion vehicles, ensure engine coolant is topped up. Never open a hot radiator cap. Also check windshield washer fluid.
💧
Driver Fatigue & Hydration
In-cabin heat accelerates driver fatigue. Run the AC, drink plenty of water, and take breaks every 2 hours on long trips.
Weather & Driving FAQ
Q: Are winter tyres mandatory in Belgium?
A:
No, winter tyres are not legally mandatory in Belgium. However, they are highly recommended when temperatures drop below 7°C, as standard summer tyres lose grip. Note that winter tyres are mandatory in neighboring Germany and parts of France during winter conditions.
Q: How does extreme weather affect electric vehicles (EVs)?
A:
Both extreme cold and heat affect EVs. Cold weather can reduce battery range by 20% to 30% due to cabin heating and lower battery chemical activity. Extreme heat increases battery degradation and may slow down fast-charging speeds. Pre-conditioning the cabin while plugged in is recommended in both conditions.
Q: When am I legally required to use fog lights in Belgium?
A:
In Belgium, you must use front fog lights during fog, snowfall, or heavy rain. You must use rear fog lights only when visibility is reduced to less than 50 meters due to fog or snow, or during heavy rainfall. Remember to switch rear fog lights off as soon as visibility improves to avoid blinding drivers behind you.
