Road Rules 2019

The length of road to which a traffic sign on a road (except a parking control sign) applies is worked out in the direction driven by a driver, or travelled by a pedestrian, on the road who faces the sign before passing it.

Rule 21(3) provides that a speed-limit sign applies to the length of road beginning at the sign and ending at the nearest of a different speed-limit sign, anend speed-limit sign, orspeed derestriction sign, and the end of the road. Only the nearest of those things, in the direction driven by a driver, or travelled by a pedestrian, who faces the sign before passing it, is relevant.

Parking control signand traffic sign are defined in the dictionary.

Rule 332 deals with parking control signs that display an arrow. These signs apply to lengths of road.
