Begin braking early when you come to an intersection. If you start to slide, ease off the gas pedal or brakes. Steer into the direction of the skid until you feel you have regained traction then straighten your vehicle. When a snow plow is coming towards you, allow plenty of room for the plow to pass. When the center line is being cleared and salted the plow tip may be on or over the line.
Snow plows are big, heavy pieces of equipment.
So play it safe, give them room to pass. When you approach a snow plow from behind, pass with care and only when you can see the road ahead of the plow. You should not try to pass in blowing snow, there may be a vehicle in that cloud of snow. Allow more distance between you and the plow, they may be spreading salt. Be alert when you approach a cloud of snow which covers the road, especially on passing lanes of interstates or freeways.
