Standardization of signs (Repealed)

(a) In situations where messages are required other than those herein provided for, the signs should be of the same shape and color as standard signs of the same functional type. (b) The term "legend" as used in these regulations includes all word messages and symbol designs that are intended to convey specific meanings. For purposes of design, borders are included as part of the sign legend. (c) As rapidly as feasible, signs of non-standard design or application shall be replaced by new standard signs. Signs which are not dangerously inconsistent with current standards or not clearly inadequate may remain in use for a period of normal service life.
