Road Signs: Shapes & Colours
Before you memorise individual signs, learn what the shape and colour already tell you. Get this and half the sign questions answer themselves.

Read the shape first
The outline of a sign narrows down its meaning before you read a single word.
Octagon · Stop
The only octagon in the system. A full stop, every time — even on an empty road.
Inverted triangle · Give Way / Yield
Slow down and give way. You only stop if the way isn't clear.
Triangle, red border · Children ahead
A warning. Something ahead to prepare for — it doesn't order you to act.
Circle, red border · No entry
A prohibition. The red ring means “you must NOT”.
Circle, solid blue · Keep Left
A command. Solid blue means “you MUST”.
Then read the colour
Colour is a code. Learn it once and it works on signs you’ve never seen.
Red
Stop, danger, or prohibition. A red ring or border always means “you must not”.
Blue
A command — “you must”. (Also the highest-class A1 freeway direction signs.)
Green
Freeway and rural direction signs — not blue, which is a common trap.
Brown
Tourism and places of interest.
White background
A permanent sign.
Yellow background
A temporary sign — roadworks.
Common trap: rural direction signs are green, not blue. Blue is reserved for the highest-class A1 freeways — and a yellow background always means temporary roadworks.
The two everyone confuses
Stop vs Yield is the single most-tested confusion in the learner’s test.
Stop
Come to a complete stop at the line, every time. Then go only when it's clear.
Give Way / Yield
Slow down and give way. You only stop if traffic or pedestrians are there.
How the test asks it
- “What does this sign mean?” — recognise the meaning from shape + colour.
- “What must you do when you see this sign?” — the required response.
- The trap answer: treating a Yield like a Stop, or reading a blue “must” as a red “must not”.
That’s one lesson. There are dozens more.
Every sign, rule and control — explained like this, then practised until it sticks.
