Why does the snowplow plug up my driveway? ~: Winter weather brings with it a variety of challenges and occasional frustrations. Among those is the fact that snowplows push snow against the curb and into driveway aprons. While unfortunate, this is necessary as plowing requires the snow to move from the center of the road to the curb. Plow trucks cannot turn their blades to avoid driveways as snow will fall back to the center and delay completion in clearing all streets. Please take small quantities of snow on your shovel when clearing the end of your driveway, especially when the snow is wet and heavy.
