The summer heat in the UAE is no joke, and with temperatures climbing this season, there’s one small habit that could put your car — and your safety — at risk: leaving a plastic water bottle inside your vehicle while it’s parked under the sun.

The Warning
Sharjah Civil Defense Authority previously issued a clear warning last year: “Leaving a water bottle inside your car can ignite a fire.”
It sounds surprising, but it’s true. A clear plastic bottle filled with water can act like a magnifying lens. When direct sunlight passes through it, the rays get concentrated into a single hot spot — strong enough to scorch your seats or, in some cases, start a fire inside your car.
And here’s something even more alarming — it’s not just full bottles you need to worry about. Even an empty or partially empty plastic bottle can pose a risk. The remaining air inside can still refract sunlight, and the plastic itself can warp, melt, or release harmful chemicals when exposed to extreme heat for prolonged periods.
Why It Still Matters Today
While the warning was issued last year, it’s just as relevant now as temperatures in the UAE continue to soar during the summer months. Most of us grab a bottle of water for the road and forget about it once we park. That forgotten bottle — whether full, half-empty, or completely empty — on your dashboard or seat is all it takes for things to go wrong.
What You Can Do
The fix is simple:
- Take your water bottle with you when you step out of the car — yes, even the empty ones!
- Store it in a shaded spot like the glove box or under a seat if you’d rather leave it behind
- Avoid leaving any clear bottles on the dashboard or front seat where direct sunlight hits
- Dispose of empty bottles rather than letting them roll around in your car
It only takes a second, and it could save you from a costly and dangerous situation. Stay safe this summer, and pass this reminder along to those around you.
