The ROAD FLOODED (NYW4-9) sign may be used, as necessary, to warn of a roadway section which remains passable, but is covered by water which requires greatly reduced travel speed and/or obscures a significant length of pavement.
Guidance
The ROAD FLOODED sign should be used only where the roadway remains, or is expected to remain, passable during its flooded condition. Where a roadway is, or is expected to become, impassable, it should be closed and suitably posted with ROAD CLOSED (R11-2) signs.
Where used, the ROAD FLOODED sign should be displayed only while the flood condition exists, or is imminent, and should be removed promptly when the condition subsides. Variable-message or part-time signs should be considered where road flooding occurs periodically.
