Question: A round sign with a red diagonal slash means:
Answer options:
- Permitted action ✅ Prohibited action
- Mandatory action
- Information
Correct answer: Prohibited action
Explanation: In Alberta, a red circle with a diagonal slash through a symbol indicates a prohibited action, signaling to drivers that the illustrated maneuver is strictly forbidden, such as no left turns or no U-turns. Conversely, permitted actions are represented by green circles, mandatory actions are displayed using white-on-black or green symbols, and information signs are typically brown, blue, or green rectangles. This distinction follows standard Canadian traffic regulatory sign color codes designed for quick driver recognition. Understanding these symbols is essential for the Alberta Class 7 knowledge test, where traffic sign questions are highly frequent, and adhering to them prevents hazardous driving and road test failure.
