A road warning system for indicating the presence of emergency or other conditions along a roadway or other surface includes an elongated carrier and a plurality of erectable-retractable warning means which are retracted when the carrier is disposed in a storage mode and erected when the carrier is translated from the storage mode into the utilization mode in which the warning means are erected to indicate the existence of a roadway anomaly. The carrier may consist of a wide variety of different structures, including linkages, continuous lengths of flexible-deformable material and the like. It is also contemplated that the carrier will incorporate various conductors, including electrical and fluid conductors, so that the warning means may be illuminated either electrically or by means of illuminating gases.

1. A reusable road hazard warning system for indicating the existence of hazardous conditions along a roadway or other surface, comprising: an elongated flexible carrier which, when not in use, is stored in a storage mode from which it can be payed out into a utilization mode on said roadway, said carrier conforming to said roadway configuration and irregularities and being disposable in coplanarity with said roadway and unattached thereto; a plurality of road warning elements normally maintained retracted when said carrier is disposed in its storage mode, said road warning elements being attached to said carrier and disposed in contiguity to said carrier in said storage mode, but being erectable therefrom when said carrier is payed out upon said roadway surface into its utilization mode; and an erecting means interposed between said carrier and said road warning elements to cause the automatic erection of said road warning elements as said carrier is payed out on said roadway surface. 2. The system of claim 1 in which said carrier includes detachable linkage means along its length to permit the severance of predetermined lengths of said carrier from the remainder thereof. 3. The system of claim 1 in which said carrier incorporates electrical conductor means and at least certain of said road warning elements include electrically illuminable means connected to said electrical conductor means whereby said road warning elements may provide visual indication of a hazardous condition during obscured or night conditions. 4. The warning system of claim 1 in which said carrier includes a combustible gas conduit and in which at least certain of said road warning means have a combustible gas outlet permitting ignition of said gas to impart a flare-type indication of a hazardous roadway condition. 5. The system of claim 1 in which said carrier includes cable means and said road warning elements are mounted on said carrier cable means at predetermined intervals. 6. The carrier of claim 5 in which said road warning elements are individually removable from said carrier cable means. 7. The road warning system of claim 5 in which said road warning elements may be adjusted along the length of said cable means to permit selective spacing of said road warning elements. 8. The road warning system of claim 1 in which said elongated carrier includes a plurality of receptacles located at predetermined intervals along the length of said carrier and said road warning elements are seperably inserted into said receptacles whereby said road warning elements may be installed in or removed from said receptacles.
