First, it's smart to prepare for ice and snow by using markers to mark the perimeter of your driveway to avoid damage to the vegetation.
There's a nifty product you apply about 1 1/2 to 2 hours before the snow hits which acts as an "anti-snow agent". Essentially this reduces snow accumulation and therefore the formation of ice. One gallon of this liquid product protects 1000 square feet and lasts about 2 weeks. The product is called Bare Ground and can be used from 35 degrees to -20. Anything above 35 degrees F will cause a slippery surface.
Other options are to shovel the snow before it becomes ice or laying down heavy plastic over small areas before the storm.
When it comes to chemicals...
Sand does not remove the ice, however it does provide traction. You may even want to use a pick to chop up ice, shovel it, and then spread the sand out evenly over remaining icy spots.
Rock salt aka sodium chloride is probably the most well known product to remove ice. It is inexpensive and usually readily available. Keep it mind it does damage vegetation and can damage metal and concrete.
CMA or Calcium Magnesium Acetate is a low toxicity product that's safe for vegetation, concrete, and metal. However, it is one of the slower working products and more expensive too.
Potassium Chloride is OK for plants and concrete but is not very effective. It also will work only to the lowest temperature of 12 degrees F.
Calcium Chloride is fast acting and effective to -25 degrees F. It will likely cause damage to concrete, vegetation and metal and tends to leave an oily residue.
Magnesium chloride is also one of the best known products. If followed as directed, it will not harm vegetation, metal, or concrete. It will usually leave an oily residue.
With possibly the next few days being a snow storm over in the Seattle area, take care and do as little driving as possible!
