Given the onset of cold weather, more and more of us are experiencing misty car windows.
Your windows will steam up when the air inside your car is warmer than the air outside and is carrying more humidity. This inside air is cooled near the glass, allowing the humidity to condense and form mist.
The Institute of Advanced Motorists’ chief examiner Peter Rodger recommends that drivers prepare their cars before they travel:
“Your windows are your eyes when you get behind the wheel,” Peter Rodger said, “and it is dangerous to drive if you can’t see clearly from your windows. Be five minutes late rather than venture down the road in this way”.
