Road Shoulder Barrier Board
Road Shoulder Barrier Board used for directing traffic away from Highway Road Shoulder. These Traffic control boards are used on main roads and highways. Notably, they comply to Australian Standards. The Class 1W reflective diagonal stripe bars indicate which direction. Indeed, a bar sloping from the right, down to the left, means keep left. Similarly, diagonal bars sloping from the left, down to the right, means keep right. Shoulder boards differ from centre lane barriers inasmuch as the other side of the bar is the same direction. For example, say this barrier was see through, the sloping bars would be aligned when looking through. Indeed, they are the same both sides. Consequently, care must be taken placing the Roadside Barrier Boards as to which way the stripes slope for traffic guidance.

MUTCD traffic control information
Barrier boards shall be 150 mm to 200 mm in height and not more than 4 m in length. They should be mounted on trestles or fixed posts at about 1 m above the pavement. The colour combination used for barrier boards shall be alternate diagonal stripes of black and retroreflective yellow, terminating in yellow at each end. Barrier board designs for use in Queensland are given in TC9215 and TC9224. A Barrier Board shall not be placed parallel to the direction of traffic flow.
