Salt, Sand, or Kitty Litter for Traction in Winter?
It's tricky and dangerous to drive in winter. But you won't be driving at all if your car gets stuck in a place where the tires have no traction. You will want to have something in your car that can give you traction when you need it.
The typical materials used for this purpose are salt, sand, and kitty litter. Which one is best for you? It depends on your needs. Salt will melt ice and snow and absorb moisture, which will make your driveway easier to get out of, but it won't give you any immediate traction if you're trying to get out of a slushy embankment.
Sand will give you immediate traction, but it won't absorb moisture. Kitty litter will also give you immediate traction and absorb moisture, but it will absorb so much that it will stick to the driveway. You should use sand for making your driveway drivable and kitty litter for emergency situations.
