Adverse weather significantly increases risks on UK roads, particularly during the autumn and winter months. Heavy rainfall, icy surfaces and snowy conditions all affect visibility, traction and vehicle handling. To ensure the safety of both drivers and passengers, it is essential to understand how to prepare your vehicle, adapt your driving behaviour and respond appropriately to hazardous conditions. The following guidance outlines best practices for safe driving during challenging weather in the United Kingdom.
1. Driving in Heavy Rain
Heavy rainfall is common across the UK and can create serious hazards, including reduced visibility, slippery road surfaces and unexpected flooding.
Primary Risks
- Limited visibility for drivers and other road users
- Increased stopping distances
- Aquaplaning caused by water building up between tyres and the road
- Localised flooding in low-lying areas or near drains
Professional Recommendations
- Reduce speed to maintain full control and compensate for extended braking distances.
- Use dipped headlights to improve visibility and ensure your vehicle is clearly seen.
- Maintain a minimum four-second gap between your car and the vehicle ahead.
- Avoid harsh braking or sharp steering movements, which can lead to loss of control.
- Approach standing water with caution; if water depth is unclear or appears too deep, do not proceed.
- If your vehicle begins to aquaplane, lift your foot off the accelerator, keep the steering straight and allow the tyres to regain contact with the road.
2. Driving on Icy Roads
Icy conditions—particularly black ice—are among the most dangerous for drivers, as traction is significantly reduced and hazards can be hard to detect.
Primary Risks
- Extremely low grip levels
- Sudden and unexpected skidding
- Difficulty controlling the vehicle, even at moderate speeds
Professional Recommendations
- Assume ice is present when temperatures fall to 3°C or below, especially early mornings and late evenings.
- Drive slowly in higher gears to reduce the likelihood of wheel spin.
- Avoid abrupt braking, acceleration or steering inputs.
- Increase your following distance to at least 10 seconds.
- Take extra care on bridges, shaded areas, rural roads and exposed routes, where ice forms first.
- In the event of a skid, steer gently in the direction of the skid until control is restored.
3. Driving in Snowy Conditions
Snowfall can severely compromise visibility, reduce tyre grip and make manoeuvring more challenging.
Primary Risks
- Limited traction on snow-packed surfaces
- Restricted visibility due to falling or drifting snow
- Difficulty braking and steering
Professional Recommendations
- Clear all snow and ice from the roof, windscreen, mirrors, lights and number plates before setting off.
- Move off in second gear to minimise wheel spin.
- Accelerate, brake and steer progressively, keeping overall speed low.
- Allow significantly greater stopping distance—up to ten times the normal dry road distance.
- Use fog lights only when visibility is severely reduced, and remember to switch them off when conditions improve.
- Avoid overtaking unless absolutely necessary and safe.
- Carry essential winter items, including a blanket, mobile charger, de-icer, ice scraper, torch, water and non-perishable snacks in case of delays.
4. Preparing Your Vehicle for Severe Weather
Ensuring your vehicle is fit for winter driving is a crucial component of road safety.
Vehicle Preparation Checklist
- Tyres: Maintain at least 3mm tread depth; winter tyres are advisable in rural or high-altitude regions.
- Battery: Cold weather reduces efficiency; replace weak batteries before winter.
- Screenwash: Use winter-grade screenwash to prevent freezing.
- Lights: Clean and check all external lights for full functionality.
- Wipers: Replace worn or ineffective blades and ensure they are free from ice before use.
5. When to Avoid Travel
In some circumstances, refraining from driving is the safest option.
Avoid travelling when:
- A Met Office red weather warning is in effect.
- Roads are heavily flooded, blocked or extremely snow-covered.
- Visibility is too poor to safely judge road markings or hazards.
- Your vehicle is not suitably equipped for the conditions.
Conclusion
Driving in heavy rain, icy conditions and snow requires heightened awareness, careful planning and a disciplined approach to vehicle control. By preparing your vehicle adequately, adjusting your driving style and responding cautiously to changing weather, you can significantly reduce the risk of accidents. Ultimately, if conditions appear too severe or unpredictable, choosing not to drive may be the most responsible decision.
