The road sign, particularly for use on road works and the like, comprises a stand 2, a sign plate 4, a bracket 5 to support the sign plate on the stand so that the sign plate can rotate from a first to a second position relative to the stand, and a motor 9 for rotating the sign plate. The motor is preferably operated by remote control and powered by a battery 11 or solar powered. The sign plate may be designed to rotate by 90 degrees or 100 degrees between the first and second positions. |
