Shoveling Tip to Stop Snow From Blocking Your Driveway
After a snowstorm, you may find you have already shoveled your driveway, just to have it plowed in again once the snowplow comes through.

Check out the below diagram for a look at how you should shovel. Here is a video published by the Virginia Department of Transportation that also helps to describe this technique:
