Question: What shape and colour identifies a stop sign?

Answer options:

  • Yellow diamond ✅ Red octagon
  • Green rectangle
  • Orange diamond

Correct answer: Red octagon

Explanation: A red octagon is the universal standard for stop signs in Alberta, requiring drivers to come to a complete halt at intersections. In contrast, yellow diamonds indicate warning signs for potential hazards ahead, green rectangles provide guide or informational directions, and orange diamonds signal active construction zones. This color-and-shape coding system, standardized under Alberta's Traffic Safety Act guidelines, ensures drivers can instantly recognize traffic control commands even in poor visibility. Mastering sign identification is essential for the Alberta Class 7 knowledge exam, as shape and color recognition questions appear frequently.
