Summer is a popular time for road trips, family holidays, and longer journeys across the UK. But warmer temperatures, bright sunlight, busy roads, and sudden changes in weather can create additional challenges for motorists.
Preparing your car before setting off can help you identify potential problems before they turn into a breakdown. Simple checks such as inspecting your tyres, checking fluid levels, and testing your air conditioning can make a difference, while good driving habits can help you stay comfortable and focused behind the wheel.
In this guide, Warranty Direct shares practical summer driving tips for UK motorists, covering vehicle preparation, hot-weather driving, road-trip safety, overheating and the role a car warranty can play when your vehicle develops a covered mechanical or electrical fault.
Summer driving can bring warmer temperatures, brighter sunlight, longer journeys, and increased traffic, particularly during school holidays. These conditions can affect your comfort, concentration and visibility behind the wheel.
The following summer driving tips can help you prepare for your journey and respond safely to different conditions on the road.
Before setting off on a long journey, make sure your vehicle is ready for the trip.
You don't need to carry out a full mechanical inspection yourself, but basic checks can help identify obvious problems before you leave. Pay attention to your tyres, fluid levels, lights, windscreen, wipers, and other essential areas.
If your vehicle is due to a service, consider arranging it before a particularly long journey. It's much easier to deal with a potential problem while you're still at home than when you're on a road trip for several hours.
Your tyres are one of the most important safety components on your vehicle.
Check the tyre pressures when the tyres are cold and follow the figures recommended by your vehicle manufacturer. If you're carrying additional passengers or luggage, check whether your vehicle requires different pressures for the increased load.
Also look for:
The Highway Code states that tyres should be correctly inflated according to the manufacturer's specification and suitable for the load being carried.
Don't wait until a tyre problem develops during your journey. If you notice significant damage or unusual wear, have the tyre inspected before travelling.
Keep drinking water available when travelling, particularly during longer summer journeys.
Warm temperatures combined with traffic delays can make a journey uncomfortable, and dehydration can make it harder to stay focused.
If you're travelling with children, older passengers or pets, make sure you carry enough water for everyone and plan suitable stops along the route.
Long-distance driving requires sustained concentration. Heat, an uncomfortable cabin and spending several hours behind the wheel can make fatigue more noticeable.
Plan regular breaks into your journey rather than waiting until you're already tired.
During a break, get out of the vehicle, stretch your legs, drink some water, and take enough time to feel refreshed before continuing.
If you feel tired while driving, don't try to push through simply because you want to arrive sooner. Find a safe place to stop and take a proper break.
The Highway Code also advises keeping your vehicle well-ventilated in hot weather to help avoid drowsiness.
Bright summer sunlight can make it difficult to see clearly, particularly when the sun is low in the sky.
Glare can affect your ability to see:
Keep your windscreen clean and make sure your wipers are working properly. Use your sun visor where appropriate, and suitable sunglasses may also help reduce glare.
If sunlight significantly affects your visibility, slow down and, if necessary, stop somewhere safe. The Highway Code provides specific guidance for dealing with bright sunlight while driving.
A vehicle that has been parked in direct sunlight can become very hot before you even begin your journey.
Where possible, park in the shade. A suitable windscreen sunshade can also help reduce heat build-up inside the cabin.
Before setting off, allow hot air to escape and use your vehicle's ventilation or air-conditioning system appropriately.
A comfortable cabin can make a long journey more pleasant, but don't use air conditioning or an open window as a substitute for taking a break if you're tired.
Summer can mean increased traffic around popular holiday destinations, airports, coastal areas, and major routes.
Congestion can be frustrating, but trying to make up lost time by driving aggressively can increase risk.
Instead:
Giving yourself more time can reduce the pressure to rush when your journey takes longer than expected.
Summer weather isn't always dry and sunny. Heavy rain can arrive quickly after a period of warm weather, reducing visibility and road grip.
When driving in heavy rain:
The Highway Code states that stopping distances in wet conditions are at least double those required on dry roads.
Don't assume that because it's summer, road conditions will remain dry throughout your journey.
A parked vehicle can become dangerously hot, even when the outside temperature doesn't initially feel extreme. Never leave children, vulnerable people or pets unattended in a parked vehicle.
If you're travelling with young children or pets, plan your stops around their needs and make sure everyone can leave the vehicle safely when you stop.
This is one summer driving precaution where there should be no compromise.
Even a carefully planned journey can be disrupted by traffic, road closures, weather or a vehicle problem.
For longer journeys, consider carrying:
You don't need to overload the car with equipment. The aim is simply to have the essentials available if your journey takes considerably longer than planned.
Summer heat doesn't only affect your vehicle. It can also affect how comfortable and alert you feel behind the wheel.
Understanding these effects can help you make better decisions during longer journeys, particularly when temperatures are high or traffic is slow-moving.
A hot, uncomfortable cabin can make an already tiring journey more difficult. Keep the vehicle appropriately ventilated and use the air conditioning when necessary. Most importantly, take regular breaks and don't continue driving if you're struggling to stay alert.
Long journeys in warm weather can make it easy to forget to drink enough water. Keep water available and use your rest stops as an opportunity to stay hydrated.
Glare can make it harder to see the road ahead and identify other road users. Clean your windscreen, use your sun visor, and wear suitable sunglasses if they improve your visibility.
Being stuck in traffic on a hot day can be frustrating and uncomfortable. Allow enough time for your journey so you don't feel pressured to make up lost time. Keep your attention on the road and maintain an appropriate distance from the vehicle ahead.
Hot and sunny conditions don't require a completely different style of driving, but they do require greater awareness of visibility, comfort and fatigue. The safest approach is to adapt to the conditions rather than assume that clear skies automatically mean easy driving.
Bright sunlight, glare, congestion, or unexpected changes in road conditions can affect how quickly you can react. Your speed should always be appropriate for the conditions, traffic, and visibility.
Maintaining a suitable following distance gives you more time to react if the vehicle ahead brakes suddenly. This becomes even more important when traffic is unpredictable or road conditions change.
Summer journeys can involve passengers, music, navigation systems, and frequent stops, but the driver's attention should remain on the road. Set your navigation before setting off and avoid handling your phone while driving.
A dirty windscreen can make glare significantly more difficult to manage. Clean both the inside and outside of the windscreen and make sure your wipers can clear water effectively.
Summer weather isn't always predictable. Heavy rain, strong winds or sudden changes in visibility can make conditions very different from those you experienced when you started your journey.
The key is to recognise the change and adapt your driving rather than continuing at the same speed.
Rain can reduce visibility and tyre grip. If conditions deteriorate, reduce your speed and leave a larger gap between your vehicle and the one ahead.
Avoid driving through standing water where possible. If you encounter water on the road, slow down and avoid sudden steering or braking. Be particularly cautious if you cannot judge its depth.
Heavy rain can make it difficult to see road markings, vehicles, and hazards ahead. Use your lights appropriately and increase your following distance.
Road conditions can change after periods of hot, dry weather followed by rainfall. Don't assume that a familiar route will have the same grip and visibility conditions throughout your journey.
A longer summer journey deserves a little more preparation than an everyday trip. While the focus of this guide is safe summer driving, it's also important to make sure your vehicle is ready before you set off.
Check the essentials, including your tyres, fluid levels, brakes, lights, windscreen, and air conditioning. If you notice anything unusual, it's better to have it checked before a long journey rather than dealing with a problem on the road.
Your vehicle's condition can have a direct impact on your journey, particularly when you're travelling long distances in warm weather. Simple checks can help you identify potential issues before you leave.
For a more detailed guide to preparing your vehicle for summer, see our Summer Car Maintenance Checklist. It covers important checks including tyres, coolant, engine oil, battery, air conditioning, and other areas of your vehicle that deserve attention before summer travel.
Taking care of these checks before your journey means you can concentrate on the road itself and enjoy a more comfortable and prepared summer trip.
Check your route before leaving and consider alternative options if you're travelling during a particularly busy period. Don't rely entirely on your navigation system to make every decision for you. Remain aware of road signs, traffic conditions and any changes to your route.
Look at traffic conditions and the weather forecast before setting off. If significant congestion or severe weather is expected, consider whether changing your departure time or route could make the journey easier and safer.
Identify suitable places to stop before starting a long journey. Regular breaks are particularly important when travelling with children, older passengers or anyone who may become uncomfortable during a long drive.
Don't leave refuelling or EV charging until the last possible moment. Plan suitable stops along your route, particularly if you're travelling on unfamiliar roads or during busy holiday periods.
If you're travelling with children, pets or older passengers, consider their needs before setting off. Carry enough water, plan suitable breaks, and make sure everyone is comfortable before beginning a long journey.
Overheating can become a serious problem if you continue driving after a warning appears. The immediate priority is to protect yourself, your passengers and the vehicle rather than trying to reach your destination.
Depending on your vehicle, signs can include:
If you notice signs of overheating, find a safe place to stop as soon as practical. Switch off the engine and allow it to cool.
Never remove a coolant or radiator cap while the engine is hot. The cooling system can be pressurised, and hot coolant can cause serious burns.
Continuing to drive an overheating vehicle can increase the risk of further mechanical damage. If you're unsure what has caused the problem, arrange appropriate assistance rather than attempting a repair you're not qualified to carry out.
Even with careful preparation, a vehicle can develop an unexpected mechanical or electrical problem during a summer journey. A breakdown can be particularly stressful when you're travelling with family, carrying luggage or stuck in unfamiliar surroundings.
Some repairs can also be expensive, particularly when a major mechanical or electrical component fails. Having the right protection in place can help reduce the financial impact of an unexpected repair.
An extended car warranty can provide protection against eligible mechanical and electrical failures, subject to the terms, conditions and exclusions of the policy.
This can be particularly useful when your manufacturer's warranty has expired, and you're faced with an unexpected repair bill. Instead of having to meet the full cost of an eligible repair yourself, your warranty can provide financial protection for covered components.
It's important to remember that a warranty is not a replacement for regular servicing or maintenance. Keeping your vehicle properly maintained remains essential for safe summer driving.
A mechanical or electrical fault isn't the only concern during a summer journey. If your car breaks down at the roadside, having roadside assistance can help you get the support you need to continue your journey or get your vehicle to a suitable repair facility.
Warranty Direct's extended warranty plans come with AA Roadside Assistance, providing additional support if you experience a breakdown, subject to the applicable policy terms and conditions.
Having both warranty protection and roadside assistance means you're not only considering the potential cost of an eligible repair, but also what happens if your vehicle leaves you stranded during a journey.
Summer driving should be about enjoying the journey, not worrying about what could go wrong. Checking your vehicle, planning your route, taking regular breaks and adapting your driving to changing weather conditions can all help you travel more safely.
However, even a well-maintained car can develop an unexpected mechanical or electrical fault. A major repair can quickly become an expensive and unwelcome cost, particularly if your vehicle is no longer covered by its manufacturer's warranty.
An extended car warranty from Warranty Direct can provide protection against eligible mechanical and electrical failures, while included AA Roadside Assistance can provide support if your vehicle breaks down during a journey. Both are subject to the applicable policy terms, conditions and exclusions.
The most important summer driving tips include preparing your vehicle before a long journey, staying hydrated, taking regular breaks, managing glare, keeping the cabin comfortable, planning for traffic and adapting your driving when weather conditions change.
Stay hydrated, take regular breaks, keep the vehicle appropriately ventilated, manage glare and avoid driving if you're too tired to concentrate.
You should also allow additional time for traffic and unexpected delays rather than feeling pressured to rush.
Keep your windscreen clean, use the sun visor where appropriate and wear suitable sunglasses if they improve your visibility. If you're dazzled by bright sunlight, slow down and, if necessary, stop somewhere safe.
Regular breaks are particularly useful during long summer journeys because heat, discomfort and extended periods behind the wheel can contribute to fatigue.
If you feel tired, stop somewhere safe and take a proper break rather than trying to continue.
Park in the shade where possible, use a suitable windscreen sunshade and ventilate the vehicle before setting off. Use your air conditioning or ventilation system appropriately during the journey.
Driving during very hot weather can be managed safely with appropriate preparation. Stay hydrated, take regular breaks, keep the vehicle ventilated and pay close attention to signs of fatigue.
If heat, glare, or weather conditions make driving unsafe, adjust your journey or stop somewhere appropriate.
Consider carrying drinking water, a phone charger or power bank, essential medication, a basic first-aid kit, sunglasses, sun protection and relevant vehicle or assistance information.
If you're travelling with children or pets, pack additional supplies based on their needs.
Stop somewhere safe as soon as practical, switch off the engine and allow it to cool. Never remove the coolant or radiator cap while the engine is hot. If you're unsure about the cause, arrange appropriate assistance rather than continuing to drive.
