Windshield fog results from condensationmoisture in the air turning into liquid on the glass surface. This occurs when the windshield temperature is lower than the dew point temperature of the air inside the vehicle. The warm, humid air inside the car comes into contact with the cold windshield, causing the water vapor to condense into tiny water droplets, creating fog.
Clear visibility through the windshield is paramount for safe driving. Obstructed vision significantly increases the risk of accidents. Understanding the underlying causes of condensation allows for proactive measures to maintain a clear view. Historically, rudimentary methods such as wiping the windshield with a cloth were employed, but modern automotive systems offer more sophisticated solutions.
