Traffic Signs: Shape, Colour, and Meaning
Reading signs by shape and colour
Sign questions reward pattern recognition. Learn the categories rather than memorizing individual signs.
- Octagon, red: stop. Come to a complete halt behind the line or crosswalk.
- Inverted triangle, red/white: yield. Slow down and give way; stop only if necessary.
- Diamond, yellow: warning - curves, intersections ahead, pedestrian crossings, slippery pavement.
- Rectangle, white with black text: regulatory - speed limits, turn restrictions, lane use.
- Rectangle, green: guidance and distance information.
- Pentagon, yellow: school zone or school crossing.
- Circle with a diagonal slash, red: prohibition (no entry, no turns).
- Railway crossbuck (X-shaped): railway crossing; a signal or gate may accompany it.
Traps to watch for
- Yellow vs. white: yellow means warning, white means a rule you must obey. A question may show a yellow diamond with a symbol and ask whether it is a warning or a regulation.
- Construction signs are orange, not yellow - a common distractor.
- School zone vs. school crossing: the pentagon marks a crossing; the zone's reduced speed applies during posted times.
- Temporary vs. permanent: obey temporary signs and flag persons over normal signage.
Worked example
A yellow diamond shows a pedestrian symbol. Because the shape and colour signal a warning, the correct answer is to slow and watch for pedestrians ahead - not that pedestrians are prohibited or that a crossing guard is present.
Rule of thumb
Name the shape, then the colour, then the symbol. That order resolves almost every sign question.
