Safety Tips for Driving in Adverse Weather

The UK's weather can change quickly, particularly throughout autumn and winter, making it essential to know how to drive safely in challenging conditions. Here are our top tips for staying safe behind the wheel when the weather takes a turn.

1. Check Your Vehicle Before You Travel

A well-maintained vehicle is your first line of defence against adverse weather.

Before setting off, take a few moments to check:

• Tyre tread depth and tyre pressures
• Windscreen wiper condition
• Washer fluid levels
• Headlights, indicators and brake lights
• Battery health
• Fuel or charge level

For electric vehicle drivers, colder temperatures can affect battery performance and range, so it's worth planning charging stops ahead of longer journeys.

2. Slow Down and Leave More Space

When roads are wet, icy or covered with fallen leaves, your vehicle will take longer to stop.

Reducing your speed gives you more time to react to hazards and helps maintain control if road conditions suddenly change. It's also important to leave a larger gap between you and the vehicle in front.

As a general rule:

• Double your following distance in wet weather
• Increase it even further in snow or icy conditions
• Avoid sudden braking, acceleration or steering inputs

Smooth, controlled driving can make a significant difference when grip levels are reduced.

3. Driving Safely in Heavy Rain

Rain is one of the most common causes of poor driving conditions across the South West.

Heavy downpours can reduce visibility and increase the risk of aquaplaning, which occurs when your tyres lose contact with the road surface due to standing water.

If you experience aquaplaning:

• Stay calm
• Ease off the accelerator gently
• Avoid harsh braking
• Keep the steering wheel steady
• Allow your tyres to regain contact with the road

Always drive with dipped headlights in heavy rain and avoid driving through floodwater unless you're certain it's safe to do so.

4. Be Prepared for Ice and Snow

Even minor snowfall or overnight frost can create hazardous road conditions.

Bridges, shaded lanes and untreated rural roads often become slippery first, particularly across Devon, Cornwall and Somerset.

When driving in icy conditions:

• Reduce speed significantly
• Use higher gears where appropriate to reduce wheelspin
• Brake gently and progressively
• Avoid sudden movements
• Keep a greater distance from other vehicles

If conditions are severe, consider whether your journey is necessary and check travel updates before setting off.

5. Take Extra Care in Fog

Fog can appear quickly and dramatically reduce visibility, especially on rural roads and in coastal areas.

When driving in fog:

• Use dipped headlights
• Use front and rear fog lights when visibility drops below 100 metres
• Reduce your speed
• Leave extra stopping distance
• Avoid relying solely on the vehicle in front to guide your route

Remember to switch off fog lights when visibility improves to avoid dazzling other drivers.

6. Watch Out for Strong Winds

High winds can affect vehicle stability, particularly for vans, SUVs and vehicles towing trailers.

Be especially cautious when driving:

• On exposed roads
• Across bridges and viaducts
• Near large vehicles
• Along coastal routes

Keep both hands on the wheel and be prepared for sudden gusts as you pass gaps in hedges, buildings or other windbreaks.

7. Make the Most of Your Vehicle's Safety Systems

Modern Mercedes-Benz vehicles feature a range of advanced safety technologies designed to support drivers in challenging conditions.

Depending on your model, features may include:

• Active Brake Assist
• Attention Assist
• Adaptive Highbeam Assist
• 4MATIC All-Wheel Drive
• Electronic Stability Programme (ESP)
• Active Lane Keeping Assist

While these systems can help enhance safety and confidence, they are designed to assist the driver rather than replace careful driving and good judgement.

8. Carry an Emergency Kit

If you're travelling during winter or heading on a long journey, it's sensible to keep an emergency kit in your vehicle.

Consider including:

• A phone charger or power bank
• Warm clothing and blankets
• Water and snacks
• A torch
• Ice scraper and de-icer
• First aid kit

These essentials could prove invaluable if you're delayed or stranded due to adverse weather.

Stay Safe Whatever the Weather

Driving in adverse weather requires extra care, preparation and awareness. By maintaining your vehicle, planning ahead and adapting your driving style to the conditions, you can help keep yourself and others safe on the road.
