Question: A black-on-yellow sign with a curving arrow indicates:
Answer options:
- Detour ✅ A curve in the road
- Lane change
- Reverse direction
Correct answer: A curve in the road
Explanation: A black-on-yellow sign with a curving arrow indicates an upcoming curve in the road, warning drivers to adjust their speed for a change in the road alignment. Yellow signs are warning signs in Ontario, whereas detour signs are orange, lane change requirements are typically regulatory white or black, and reverse direction symbols feature a hairpin turn. Under Ontario Highway Traffic Act guidelines, yellow diamond-shaped signs always alert drivers to physical road conditions ahead rather than temporary or regulatory situations. Memorizing color-coded signage is vital for the G1 exam, as identifying road warnings ensures safe speed adjustments and prevents collisions during the road test and beyond.
