Question: In fog you should:

Answer options:

• Use high beams ✅ Use low beams or fog lights and slow down
• Drive on the shoulder
• Tailgate the car ahead

Correct answer: Use low beams or fog lights and slow down

Explanation: Under official Ontario Ministry of Transportation rules, driving in fog requires low-beam headlights or fog lights and reduced speed because low beams direct light downward, minimizing the blinding glare reflected back by moisture droplets. High beams are incorrect because they reflect directly off the fog, severely reducing visibility. Tailgating and driving on the shoulder are dangerous, illegal actions that increase collision risks. This concept is highly relevant for the G1 exam, as candidates must know the proper headlight settings for various adverse weather conditions to ensure safe stopping distances and avoid common exam pitfalls regarding high-beam usage in low-visibility scenarios.
