Question: A black-on-orange diamond 'DETOUR' sign means:
Answer options: ✅ The road is closed; follow the marked detour
- Construction will start
- Slow down
- Yield
Correct answer: The road is closed; follow the marked detour
Explanation: Ontario traffic laws stipulate that orange-and-black diamond-shaped signs indicate temporary conditions like construction zones. A detour sign specifically signals that the route ahead is fully closed, requiring drivers to follow the marked detour path to bypass the obstruction. While other orange signs warn motorists to slow down or indicate that construction is ahead, this specific sign dictates an immediate route change, making general warnings about construction starting or slowing down incorrect. Understanding temporary traffic control signs is highly relevant for the Ontario G1 exam, as drivers must accurately identify signs that dictate mandatory path changes in construction zones.
