7.4.2a Design

The chevron sign shall be a vertical rectangle. No border shall be used on the chevron sign. The point of the arrow in chevron shall indicate the direction of travel. They shall be visible for at least 150m to provide the road user with adequate time to react to change in alignment. The minimum lateral offset of the chevron sign shall be 1.8m from the edge of the pavement.

SHOWING THAT THE SPACING OF THE CHEVRON SIGNS ALLOW THE DRIVER TO SEE AT LEAST (3) SIGNS IN VIEW WHILE NEGOTIATING THE CURVE UNTIL THE CHANGE IN ALIGNMENT ELIMINATES THE NEEDS FOR THE SIGNS AS CONTAINED IN THE 4TH PARAGRAPH OF SECTION 620.2.2, DESIGN FOR ITEM 620 - CHEVRON SIGNS

The chevron signs shall be installed on the outside of the curve, set up aligned with the approaching traffic at right angle to a driver's line of sight. Two-sided chevron signs may be used on two-lane, two-way roads to guide driver's travelling in both directions. It is recommended that the spacing of the chevrons signs should allow the driver to see at least three (3) signs in view while negotiating the curve, until the change in alignment eliminates the need for the signs. Chevron signs shall be mounted clear of roadside vegetation and clearly visible under headlight illumination by night. Chevrons should be installed 1.5m above the ground in rural areas and 2.2m in urban areas. The recommended spacing for chevrons within a curve is shown below.
