Abstract: A portable, temporary roadway sign stand (10) with a single upright support (11), a first stabilizing means (12), and a horizontal stabilizing means (13), all of which are telescopically extensible to allow for a great range of adjustable features. Such features include, but are not limited to, improved stability, quick and easy assembly and disassembly, compaction, and variable sign display height. Other constituents of sign stand (10) provide essential wind rigidity, adjustment for various sign types and sizes, conformity to uneven, irregular and/or sloping terrains, and break-away joints for safety purposes. The present invention is also designed to conform to federal, state, and local regulations, as well as the "standards of operation and use" established by other groups.
