While driving, the inside of your vehicle’s windscreen begins to mist over. How can you counteract this?

The selected combination of turning on the climate control system and directing airflow onto the windscreen at full power is correct because both actions effectively reduce humidity inside the vehicle, preventing the windscreen from misting over. In Germany, maintaining good visibility is crucial to road safety, and the Straßenverkehrsordnung (StVO) emphasizes the importance of clear windows while driving. Opening the window may not be advisable when the outdoor humidity is high, as it can introduce more moisture into the vehicle, making the problem worse. Therefore, using the vehicle's climate control system is the most reliable method to ensure a clear view while driving.
