Drivers must be feeling how intensely hot their cars get even after being parked outside for just a short while amid the relentless heatwaves.

In fact, the interior temperature of a vehicle can soar up to 90°C (194°F).

Caution is required against various safety accidents.

According to the Korea Transportation Safety Authority, the number of vehicle fires increases by 10% to 20% in July and August compared to usual periods.

This is because the interior temperature of vehicles exposed to direct sunlight for long periods can rise up to 90°C (194°F).

Leaving items inside the vehicle, especially on the dashboard beneath the front windshield, can lead to explosions or fire accidents.

In particular, auxiliary batteries and disposable lighters have an increased risk of exploding at high temperatures, so they must be taken out of the vehicle.

Otherwise, it is advisable to store them in a place not reached by direct sunlight.

Also, many people leave transparent bottled water in their cars.

This can act as a lens that gathers sunlight to a single point, potentially causing a fire.

If you have to park your car outdoors, parking it with the rear facing the sunlight can reportedly help reduce the rise in interior temperature to some extent.

Using sunshades or similar items to cover the windows can also be helpful.
