Put ice grippers on shoes or boots, or at least wear boots with good traction to reduce the risk of slipping and falling on the ice.
Scoop rock salt out the bag using a small plastic flower pot or a clean, plastic container. Wear gloves so that the salt doesn’t contact bare skin. If a kitchen container is used to scatter the salt, write “SALT” on it with a permanent marker so that it isn't accidentally used in the kitchen again.
Scope out any particular trouble spots on the driveway -- the places where the car tends to get stuck most often -- and salt those first. Walk from one side of the driveway to the other, shaking the salt container to distribute the salt evenly. Aim for an even, moderate covering of salt -- no need to pour it on thickly -- and keep the salt off of the lawn and any nearby plants as much as possible.
Refill the container from the bag of salt as necessary. Once the entire driveway or all the trouble spots have been treated, wait about 30 minutes for the ice to soften and begin to melt. Depending on how icy the driveway was, let the ice melt on its own or chip and shovel it away as it softens. Extremely thick ice may need to be salted more than once.
