If you are parked outside during a snow storm its a good idea to stick your wipers in an upright position on your car’s windshield. This prevents them from getting buried under snow and ice. You don’t want to mistakenly try to get your wiper fluid to spritz and ruin the motor of your wipers because they are frozen in a stationary position. Plus cleaning off your windshield will be easier because the wipers will be out of the way.
