Car Safety: What to Do When Your Windshield Fogs Up
So it's winter, but this can happen if it's cold and rainy any time of the year; your car windshield fogs up. So what do you do? If you're a new driver like me, you may have no idea!
First of all, the fog comes from water condensation on the INSIDE of the window or windshield of your car. This is why your car may fog up when you turn it on during the winter; the warmer air on the inside of the car carries moisture, which condenses when it comes into contact with the cold glass.
Since the condensation is on the inside, wipers won't help. Turning on the heat makes more fog, so even though it may be cold outside, what you're supposed to do is turn on the air conditioning on cold.
However, I highly recommend finding the defroster button in your car. This runs hot air on the windshield, evaporating the moisture. This may sound obvious, but you'd be surprised how many teens (including myself until recently) who are driving in the winter for the first time don't know this!
For a quick fix to get going, you could also wipe off the fog with dry cloth on the inside of your car.
In the winter, it's also good to start your car and leave it running for a little while before you need to go anywhere to give it a chance to warm up.
