The Winter Maintenance Policy describes the principles by which public roads are to be maintained in winter. The polict defines the wintertime level of service of the road network and the quality standards that are necessary to describe it. Because certain factors and volitions that affect the lines of action and quality standards are contradictory, the text also discusses the backgrounds, expectations, effects and special conditions of winter maintenance. This policy serves as guidelines for the level of service provided to traffic and road users. The definition of the level of service takes into account the numerous effects of operation and the realities of practical implementation. Each production unit will select its own techniques for realizing winter maintenance. They are discussed only to the extent that their selection noticeable affects traffic or the environment. Methods of realization are examined in more detail in the Winter Maintenance Manual.
