Icy road conditions can form when rain has fallen and freezes upon contact, causing dangerous driving conditions.
Water freezes at 32 degrees.
Salt is one method to prevent and treat icy roads. This method is helpful because salt lowers the freezing point of water, which will lead to melting of the ice. It also prevents falling rain or snow from being able to freeze.
At 30 degrees, one pound of salt will melt 46 pounds of ice in 5 minutes, Storm Center 7 Meteorologist Molly Coates said.
However, salt can become ineffective when the air temperature reaches 15 degrees and below, Coates said.
Magnesium chloride and calcium chloride are used in colder conditions.
Always remember to take it slow when driving on icy roads.
