What you will want to do is steer into the skid as this will help to point the front wheels and the back wheels in the same direction. If you steer against the skid, you could cause your car or truck to rotate even more.
In addition to driving at a reduced speed, the use of winter tires could also reduce the chances of your car skidding or sliding on the highway. The folks at A-1 Auto Sales will be happy to answer any winter driving questions that you may have.
