The Korea Road Traffic Authority has urged drivers and passengers to exercise extreme caution, revealing that the interior surface temperature of a vehicle parked outdoors for an extended period under scorching heat surged up to 85.5°C (186°F).

According to the authority, after parking a vehicle outdoors for about four hours in an environment with an air temperature of 34°C (93°F) on the 5th, the dashboard temperature of a black vehicle rose up to 85.5°C (186°F), while that of a white vehicle reached up to 73.7°C (165°F), showing a difference of about 12 degrees depending on the vehicle's color.

The authority explained that since the inside of a vehicle heats up rapidly in a short period, sufficient ventilation and cooling are necessary before boarding.
