Reading B.C. road signs by shape and colour

2026-10-04

ICBC's driving guide says there are three ways to read a sign: its shape, its colour and the message printed on it, and that knowing the first two helps you work out signs you have not seen before (Learn to Drive Smart, p.29). If you learned to drive somewhere else, or are new to driving, shape and colour are the quickest part to learn. ICBC also says that almost one in five knowledge test questions is about road signs (ICBC: Get your L).

Everything below comes from the key on page 29 of Learn to Drive Smart and the sign pages after it. The key is a set of pictures with short captions; where this post names a shape or a colour, that is what the picture shows.

Shapes you can read from a distance

Red octagon: stop. Stop completely, then go only when it is safe (Learn to Drive Smart, p.29–30).
Triangle pointing down: yield. Let other vehicles, and people crossing on foot, go first (p.29–30).
Diamond: a warning. The guide says "Most warning signs are yellow and diamond-shaped. They warn of possible hazards ahead." (p.33).
X-shape: railway crossing (p.29).
Five-sided sign, pointed at the top: school zone. In the key it is fluorescent yellow-green (p.29).

Circles: allowed or not allowed

A green circle around a symbol shows an action that is permitted. A red circle with a slash shows an action that is not permitted (p.29).

What the colours tell you

The key on page 29 pairs colours with meanings (Learn to Drive Smart, p.29):

White rectangle: shows driving regulations.
Black: explains lane use.
Yellow: warns of hazards ahead.
Orange: warns of construction zones.
Fluorescent yellow-green: school zones.
Blue: tells about motorist services.
Green: shows distance and direction.

Fluorescent yellow-green also appears on the school crosswalk sign (p.34). Orange signs in a work zone come with instructions you must obey, including traffic-control persons and posted speeds (p.35).

Why the white ones matter

In the key, the white rectangle "shows driving regulations". The guide's section on regulatory signs says these signs tell you about driving laws, that ignoring them is an offence under the B.C. Motor Vehicle Act, and that drivers who do not follow them may be penalized (p.30). The examples in that section include the speed limit, one-way and "do not enter" signs.

Practising

Shape and colour narrow a sign down; the words and symbol finish the job. ICBC has a free road signs practice test with every sign on it (ICBC: Get your L). Our free card on sign shapes and colours sums this up in one page, and our free practice questions include sign questions written by us from Learn to Drive Smart. They are not ICBC's test questions.
