Your car should be parked in your driveway so that the plow has access to your street and can the road.
Salt Before the Snow
A little salt will keep snow and ice from bonding to the pavement by salting before the snow has accumulated. Salt should not be used to melt every bit of snow and ice. Use only enough to break the ice / pavement bond, and then remove the remaining slush by plowing or shoveling.
Shovel to the Right
When clearing the end of the driveway, place snow to the right to prevent it from being plowed back into the driveway.
Shovel Away From Roadway
Do not pile snow in areas that will block or obscure a driver's view of the roadway and oncoming vehicles. This causes a dangerous situation for motorists who are driving on a plowed road and unknowingly hit blocks of snow placed out in the road.
