CHARLOTTE, N.C. (FOX 46 CHARLOTTE) - The decision to pre-treat roads happens 24-48 hours before a storm hits, and that's the window we’re now in as a wintry mix of weather nears.
NCDOT is preparing, all in hopes of making it a little easier for you to get around.
On Thursday night, they put 20 trucks on the road to spray brine, which is a mixture of water and salt.
In order for it to work, it must be applied when it's not raining. The brine keeps the snow and ice from bonding with the road's surface.
The focus just a couple of days ahead of when the storm is expected to hit is major interstates in Mecklenburg, Cabarrus and the Monroe Expressway in Union County.
Crews are also treating parts of Anson and Stanly counties.
On Friday, NCDOT will pre-treat major roads in Alexander, Catawba, Cleveland, Gastson, Iredell and Lincoln counties.
Come Sunday, you can expect to see around 100 dot trucks on the road with about 200 crews. They will be working 12-hour shifts until the storm is done.
As you can imagine, the work is far from over. Road crews will be out leading up to and during this storm, and NCDOT is asking that you give drivers the space to do their jobs.
