With winter weather predicted to hit parts of the state on Friday, N.C. Department of Transportation crews in many regions are pretreating roads and taking other steps to prepare for the storm.

NCDOT maintenance crews are using a salt-water mixture called brine, which is a cost-effective way to help prevent snow and ice from bonding to the pavement.

Statewide, more than 1,900 trucks are equipped with snow plows and graders in addition to 325 front-end loaders and backhoes and 450 motor graders. NCDOT has 146,500 tons of salt on hand. A typical statewide frozen precipitation event requires 40,000 tons of salt.

Here’s what crews are doing across the state to prepare for the storm:

Greater Charlotte area, including Rowan County — Salt brine is being applied to interstates, U.S. and N.C. routes, bridges, ramps and main lines of primary roads. The process will pause during the afternoon commute and resume if needed later. Once that is completed, equipment will be refitted with plows and spreaders and be on standby until needed.

Triad region — Salt brine is being applied to interstates, U.S. and N.C. routes, bridges, ramps and main lines of primary roads. The process will pause during the afternoon commute and resume if needed later. Once that is completed, equipment will be refitted with plows and spreaders and be on standby until needed.

North Carolina mountains and foothills — Crews are treating major roadways across the mountains and foothills with brine. Once that is completed, equipment will be refitted with plows and spreaders and be on standby until needed.

Triangle region — Crews began brining interstates and major routes, bridges, ramps and main lines of primary roads on Wednesday and continue today. Once that is completed, equipment will be refitted with plows and spreaders and be on standby until needed.

Eastern North Carolina — Crews began brining interstate routes, including I-95 and I-40, today and will then move on to work on U.S. and N.C. highways and other major routes. Once that is completed, equipment will be refitted with plows and spreaders and be on standby until needed.

Coastal areas — Crews in northeastern coastal counties are brining major routes. Forecasts call for fewer problems southeast of U.S. 64, so NCDOT crews will be on standby in far southeastern counties and will go into action if it appears icy weather will affect those areas.

As crews continue to pretreat roads, remember to leave plenty of distance between your vehicle and the trucks spraying brine.

Because most North Carolina motorists rarely have to deal with icy roads, here are a few cautionary notes to remember when the precipitation begins:

• Slow down.
• Bridges and overpasses freeze first.

• Put away the cellphone!
• Use only gentle pressure on both the accelerator and the brakes to avoid skidding.

• Give other motorists plenty of room in case you or the other drivers begin to slide.

Check conditions before you go. Motorists can access real-time information about changing road conditions across the state in a number of ways:
