The ICY PAVEMENT ZONE (NYW4-10) sign may be used, as necessary, to warn of roadway sections subject to unusual or unexpected pavement icing.
Guidance
The ICY PAVEMENT ZONE sign should be used only where it has been determined that recurrent pavement icing in an isolated section of otherwise clear roadway constitutes an unusual hazard. The sign should not be used in conjunction with normal wintertime storm-related snow or ice conditions.
Where used, the ICY PAVEMENT ZONE sign should be displayed only during periods when icing is likely to occur. Variable-message or part-time signs should be considered for locations subject to periodic posting.
The ICY PAVEMENT ZONE sign should be supplemented with a Distance plaque where the affected roadway section is 1000 feet or longer.
Additional ICY PAVEMENT ZONE signs, supplemented with Distance plaque stating the distance to the end of the affected section, should be placed at suitable locations (for example, after intersections), and at appropriate intervals, on long icy pavement zone roadway sections. Where an additional sign is placed within 1000 feet of the end of the section, the Distance plaque should be omitted.
