Abstract
An emergency warning device comprising a base, three arms extending upwardly from the base to define an equilateral triangle, one of the arms extending horizontally on the base and the other two arms extending upwardly. Each arm has reflective and fluorescent means on opposed surfaces thereof. Vane devices are constructed and arranged, shaped and positioned on the equilateral triangle and such that air flow against a face of the triangle produces a downward force tending to prevent movement of the device relative to a road surface.
