NOTES

1  Arrows dispersed over width of route. Arrows may be curved. Where the traffic lane is converging, arrows should be oriented to the approximate average directions of the side boundaries.

2  Arrow omitted at intersections (other than roundabouts) to avoid implying priority of one lane.

3  Separation line 3 mm wide where chart scale permits.

4  Tint light enough not to obscure detail beneath it.

5  If traffic lanes are separated by natural obstacles) may be replaced by the symbol for general maritime limits at the boundaries of the lanes.

6  Stems of dashes point towards the area in question.

7  Symbol intended for tracks to be followed closely through inadequately surveyed areas.

8  Legend "Precautionary area" or its national language equivalent may also be used within the precautionary area instead of the symbol.
