I should have expressed myself more clearly. The plow truck tires pack down the snow so hard that it turns to something akin to ice that can't be removed with a shovel. Eventually it does turn to ice. The hard/snow ice is only where the tires pass. I think we've all experienced this even with driving our own vehicles over snow in our driveways. Pressure and weight harden snow. Best example: snow shoveled from a roof turns to something close to concrete. I've had to take an AX to that snow many a time. Another example: snow falling on a glacier turns to ice as it compacts.
There is ice in my driveway right now from where the mailman drove his truck on it yesterday. So yes, the plow truck does cause the ice. Of course, this only causes a problem if the snow isn't plowed down to the asphalt.
