Question: Which shape is typically used for a Stop sign in Alberta?

Answer options:

• Square
• Circle
• Triangle ✅ Octagon

Correct answer: Octagon

Explanation: In Alberta, a stop sign is always an octagon because its distinctive eight-sided shape allows drivers to recognize the command instantly, even when the sign is viewed from behind or obscured by snow. Other shapes convey different meanings: triangles are reserved for yield signs, squares or rectangles indicate regulatory and physical guides, and circles typically warn of railway crossings. Under the Alberta Driver's Guide, traffic signs are strictly standardized by shape and color to facilitate rapid decision-making. Memorizing these physical silhouettes is essential for the Class 7 knowledge exam, as questions often test your ability to identify signs purely by their shape.
