Different types of storms require the use of different techniques.
- The decision whether to salt or plow depends upon the predicted weather conditions. For example, if the temperature is below 20 degrees and not expected to rise, salt will not be effective. If the sun is shining and the temperature is 20 degrees or more and expected to remain steady or to rise, then salt would be more effective.
- The decision whether to plow or salt is made with great consideration and based on the latest weather information available. Plowing under the wrong conditions can create a polished road surface, resulting in dangerous glare ice.
High winds can cause a precarious situation. Adding salt/sand to drifting conditions can seriously increase the buildup of snow and ice on a roadway making it more treacherous. At times, the best action would be to limit the amount of salt/sand as to prevent heavy drifting and snow/ice buildup. The decisions made by experienced crew and supervisory personnel are critical under these conditions.
