Summers in India are now longer, harsher, and more intense. While open highways and freshly built expressways call out to travellers and road trippers, summer driving today comes with its own set of modern-day risks—especially when you're cruising at triple-digit speeds on roads like the Delhi–Mumbai Expressway or the Samruddhi Mahamarg. The heat isn’t just a discomfort—it’s a potential hazard, both to your vehicle and to you.

Here’s a fresh 2025 take on seven must-follow summer driving tips, designed especially for Indian road and weather conditions.

1. Tyre Health is Non-Negotiable

Your tires are the only part of your car in contact with the road, and in summer, they’re under tremendous stress. As temperatures rise, air inside the tyres expands, leading to overinflation—one of the key reasons behind high-speed tyre bursts. It's important to check tyre pressure when the tyres are cold and ensure it matches the manufacturer’s recommended levels. Equally critical is checking the tread depth and sidewall condition. Worn-out treads or cracked sidewalls on scorching tarmac can compromise grip and control. And while we often forget about the spare wheel, it’s your emergency saviour—keep it road-ready too.

2. Keep Your Engine—and Your Cabin—Cool

The Indian summer sun can be brutal on your car’s engine, especially during long drives. Overheating is still a real risk if your coolant levels are low or your radiator fan isn’t working properly. So before any journey, make sure your engine is topped up with coolant and check if all temperature-related warning signs are clear. Also, ensure your air conditioning is functioning at its best—not just for comfort, but also to avoid fatigue while driving. Using windshield sunshades or legal UV-protective window tints can go a long way in keeping your car interiors cooler, especially if you're parked in open areas.

3. Hydrate Constantly—You and Your Co-Passengers

It’s easy to underestimate how quickly summer heat can dehydrate you, especially with the AC on. Dehydration doesn’t just lead to discomfort—it affects concentration, causes drowsiness, and slows reflexes. Carrying cool water or electrolyte-based drinks in insulated bottles or a portable cooler box can make a huge difference. Avoid caffeinated or sugary drinks during long drives as they dehydrate you faster and can leave you feeling sluggish.

4. Plan Smart: Routes, Stops, and Timing Matter

Driving in peak heat isn’t just uncomfortable—it’s inefficient and tiring. If you have the flexibility, plan your trip to avoid the hottest hours of the day, typically between 12 noon and 3 PM. Use navigation apps to map your route, but don’t just focus on the shortest distance—look for routes that have good infrastructure, reliable fuel stations, and clean rest areas. It’s a good practice to pause every couple of hours for a short break, even if you're feeling fresh. A few minutes off the wheel can go a long way in keeping you alert and reducing fatigue.

5. Keep an Eye Out for Pedestrians, Cyclists & Two-Wheelers

Summer means more people are out and about—walking, cycling, or commuting on two-wheelers. Even expressways, despite rules, are not always free of unexpected slow-moving traffic or people crossing at unauthorized points. In cities and towns, roadside vendors, schools, and local markets often see increased foot traffic. Drive cautiously, avoid sudden lane changes, and always anticipate that someone could step into your lane without warning. Giving space and being patient can literally save lives.

6. Get a Full Health Check—For Your Vehicle

A pre-journey inspection is like a health check-up—it prevents minor issues from becoming major breakdowns. In summer, your battery is especially vulnerable since heat can shorten its lifespan. Make sure your engine oil, brake fluid, and wiper fluid are all at optimum levels. If your car hasn’t had a service in a while, it’s worth taking it in for a quick check-up. Ageing components like hoses, fan belts or even rubber seals tend to wear faster in the heat, and replacing them proactively is smarter than getting stranded later.

7. Always Be Ready for the Unexpected

Even the best-prepared road trips can run into emergencies. Your car should always have a basic first-aid kit, a working flashlight, and essential tools like a jack, wheel spanner, and a spare tyre in good condition. In remote or semi-urban areas, carry extra drinking water, non-perishable snacks, and a phone charger or power bank. It’s also wise to have a printed map as backup in case of poor GPS connectivity. An emergency contact list with key numbers—mechanic, insurance, road assistance—should be easily accessible.

Bonus Tip: Ensure Digital and Legal Readiness

In 2025, tolls are digital, enforcement is AI-driven, and systems are more automated than ever. Make sure your FASTag is recharged, your vehicle insurance is active, and your Pollution Under Control (PUC) certificate is up to date. Getting stuck at tolls or paying fines can easily ruin the start—or end—of an otherwise great trip.

Final Thoughts

Summer road trips are a ritual—but one that demands caution and preparation in today's India. Between soaring temperatures, high-speed travel, and unpredictable road behavior, it’s crucial that both you and your car are ready. Keeping your car cool, your tyres fit, and yourself hydrated can go a long way in making your journey as enjoyable as the destination. The road is calling—but drive smart, drive safe.
