Abstract A reversible, portable direction indicating sign for use in road construction and maintenance work includes an upper indicia bearing panel rigidly attached to and spaced from an upright member and a lower indicia bearing panel rotatably mounted on the upright member. The lower indicia bearing panel includes an arrow imprinted thereon which can be pointed to the right or to the left by rotating the second indicia bearing panel. The word "KEEP" is printed on the upper indicia bearing panel. The word "LEFT" is printed on the lower indicia bearing panel beneath the arrow when the arrow points to the left. The word "RIGHT" is printed on the lower indicia bearing panel beneath the arrow when the arrow points to the right. When the arrow points to the right the portion of the lower indicia bearing panel on which the inverted word "LEFT" is imprinted in located in the space between the upright member and the upper indicia bearing member, so that the word "LEFT" is covered thereby. Similarly, the inverted word "RIGHT" is covered when the arrow is pointed to the left.
