After a snow or ice fall, the city streets are treated  with ordinary rock salt. In some areas, the salt is  combined with calcium chloride, which is more  effective in below-zero temperatures and which  melts ice better. This combination of salt and calcium  chloride is also less damaging to foliage along  the roadways. 



According to the snow treatment directions, which of the following is true?

If the temperature is below zero, salt and calcium chloride is effective in treating snowand ice-covered streets.
Crews must wait until the snow or ice stops falling before salting streets.
The city always salts major roads first.
If the snowfall is light, the city will not salt the streets as this would be a waste of the salt supply.

Whether there is ice on the street
The plants and trees along the street
Whether the street is a main or secondary road
