Driving in Bright Sunshine and Hot Weather: Staying Safe Behind the Wheel

Sunny weather can make driving feel easier and more enjoyable, but bright sunshine and high temperatures bring their own hazards. While many drivers prepare carefully for rain, fog, and ice, they often underestimate the risks associated with hot, dry conditions.

Understanding these risks and adapting your driving can help keep you, your passengers, and other road users safe.

The Dangers of Bright Sunshine

Strong sunlight can significantly reduce visibility, particularly when the sun is low in the sky during early mornings and late afternoons. Glare can make it difficult to see traffic signals, pedestrians, cyclists, and changes in the road ahead.

When driving into bright sunlight:

• Keep your windscreen clean, inside and out.
• Wear suitable sunglasses that reduce glare without affecting your ability to see clearly.
• Use the vehicle’s sun visor when necessary.
• Increase your following distance to give yourself more time to react.
• Be especially alert around junctions, crossings, and schools where vulnerable road users may be harder to see.

Remember that other drivers may also be struggling with reduced visibility. Anticipate unexpected actions and be prepared to react safely.

Looking After Your Vehicle in Hot Weather

High temperatures can place extra strain on your vehicle. Before setting off on a long journey, carry out some basic checks.
Pay particular attention to:

• Engine coolant levels.
• Tyre condition and tyre pressures.
• Windscreen washer fluid.
• Oil levels.
• Fuel or battery charge levels.

Tyres deserve special attention during hot weather. Increased road temperatures can cause tyre pressures to rise, and under-inflated or damaged tyres are more likely to fail. Regular checks can reduce the risk of a breakdown or dangerous blowout.

Driver Fatigue in Warm Conditions

Many people associate tiredness with night driving, but hot weather can also contribute to fatigue. A warm vehicle can make drivers feel drowsy and less alert, particularly during long motorway journeys.

To stay focused:

• Ensure the vehicle is well ventilated.
• Use air conditioning appropriately if fitted.
• Drink water regularly.
• Take planned rest breaks on longer journeys.
• Avoid driving when you feel tired or unwell.

If you notice signs of fatigue, such as frequent yawning, difficulty concentrating, or wandering thoughts, stop in a safe place and take a break.

Protecting Passengers

Hot vehicles can become uncomfortable and potentially dangerous very quickly. Children, older passengers, and pets are particularly vulnerable to heat-related illness.

Before travelling:

• Carry drinking water.
• Plan rest stops on longer journeys.
• Keep the vehicle ventilated where possible.
• Never leave children or animals unattended in a vehicle, even for a short time.

Temperatures inside a parked car can rise rapidly, even when the outside temperature feels moderate.

Adapting Your Driving Style

Dry roads generally provide better grip than wet roads, but drivers should not become complacent. Bright weather often encourages increased traffic, including cyclists, motorcyclists, pedestrians, and tourists unfamiliar with local roads.

Good practice includes:

• Maintaining safe following distances.
• Scanning well ahead for hazards.
• Checking mirrors frequently.
• Being patient around slower-moving road users.
• Remaining aware that glare can affect other drivers as much as it affects you.

A calm, defensive driving style helps reduce risk and improves overall safety.

Final Thoughts

Bright sunshine and hot weather may seem ideal for driving, but they can create serious challenges if drivers fail to prepare. Glare, reduced visibility, fatigue, vehicle stress, and increased road activity all require careful attention.

By preparing your vehicle, staying hydrated, maintaining concentration, and adapting your driving to the conditions, you can enjoy the journey while helping to keep everyone on the road safe.
