Abstract

A traffic mirror comprises a spherically curved glass pane having a front surface, a rear surface, and an outer periphery, a metal reflective layer located on the inner surface of the glass pane, and a decorative frame located directly on the glass pane. The decorative frame is an enamel-like colored material which is baked onto the outer periphery of the glass pane. The traffic mirror further comprises a supporting structure for mounting the traffic mirror onto a vertical post. The supporting structure comprises at least two supporting struts which, are attached directly to the glass pane, for example, by bolts passing through bores in the glass pane itself. The glass pane is made from thermally prestressed single pane safety glass. The traffic mirror does away with the bulky frames used in prior art mirrors of this kind.
