Question: Headlights must be turned on:
Answer options:
- Only at night ✅ From dusk to dawn and whenever visibility is poor
- Only in winter
- Only in fog
Correct answer: From dusk to dawn and whenever visibility is poor
Explanation: The correct option is correct because the Ontario Highway Traffic Act mandates headlight use from one-half hour before sunset to one-half hour after sunrise, which represents dusk to dawn, and whenever atmospheric conditions like rain, snow, or fog reduce visibility. The other options are incorrect because they are too restrictive; headlight use is not limited solely to winter, fog, or strict nighttime hours. Legally, drivers must ensure their vehicle is visible to others whenever natural light is low. On the G1 exam, this concept is highly relevant as questions frequently test the specific environmental conditions and times of day that require headlights.
