Tractor trailer drivers, when you come off the road and park on a snow covered lot, it is important to pack down the snow before setting your brakes. Roll forward and back a few times. This does 2 things, it cools down your tires so they aren’t as likely to melt the snow and then freeze forming a cup of ice that you will spin on when you are trying to leave the other is, it creates your runway when you leave so you aren’t trying to push through snow from a dead stop. When you are parked it is best to sit in the driver’s seat for about 5 minutes with the brakes not set as long as you are on level ground to let the brake drums dry out so they aren’t wet when you set them and freeze while you are on a brake. Just a few winter tips.
