You should always dress for the weather. Proper footwear is necessary, make sure that your shoes are warm and have good tread. Slip and falls often happen when entering or leaving buildings, be cautious when entering and leaving buildings.
Always keep your eye out for black ice or any slippery surface. If you do come in contact with an icy patch, take your time when walking over it or try to avoid the area all together.
It is a good idea to leave your cell phone in your pocket or purse when walking in inclement weather. Keeping your hands free can help you to keep your balance.
Take your time when walking on ice and snow covered sidewalk. Stay home if you can and avoid a potential serious accident. When possible, help out your elderly neighbors and shovel their sidewalks and driveways.
