K53 Questions on Temporary Signs
Straight from the question bank, with the answer and the reason it is correct.
A sign has a yellow background with a black symbol (same shape as a permanent sign). What does the yellow colour indicate?▼
TEMPORARY signs have a yellow background. They indicate a temporary road condition (construction, special event) and TAKE PRECEDENCE over all permanent signs in that area.
A temporary (yellow background) sign shows workers with shovels. What does this mean?▼
A temporary yellow sign with workers indicates ROADWORKS AHEAD. Reduce speed, expect changed road conditions, obey all temporary signs, and watch for workers.
A temporary speed limit sign shows 40 km/h, but the permanent sign nearby shows 60 km/h. Which applies?▼
Temporary signs (yellow background) take PRECEDENCE over all permanent signs. So you must obey the temporary 40 km/h limit, not the permanent 60 km/h sign.
A fluorescent orange/amber rectangular sign with black text reads "ROAD WORKS 500m". What does this require?▼
Orange/amber road-works signs provide advance warning of construction zones. Reduce speed, be prepared for lane closures, workers on the road, changed traffic patterns, and temporary speed limits.
