Question: An orange diamond-shaped sign indicates:
Answer options:
- A school area ✅ Temporary construction or maintenance work ahead
- A railway
- A truck route
Correct answer: Temporary construction or maintenance work ahead
Explanation: Under Ontario traffic law, orange diamond-shaped signs warn drivers of temporary conditions ahead, specifically construction or road maintenance work. In contrast, school zones are marked by fluorescent yellow-green pentagon signs, railway crossings are indicated by round yellow warning signs or crossbucks, and truck routes are shown using regulatory white signs with green circles. Official MTO guidelines use standard color-coding and shapes to ensure drivers can identify hazards from a distance. Mastering these sign shapes and colors is highly relevant for the G1 exam, as identifying road signs is a heavily tested, mandatory component of the written test.
