Question: When driving in fog you should use:

Answer options:

• High beams ✅ Low beams or fog lights
• No lights
• Hazard lights only

Correct answer: Low beams or fog lights

Explanation: The Official MTO Driver’s Handbook states that drivers must use low-beam headlights or fog lights when driving in foggy conditions. Low beams direct light downward onto the road surface rather than directly into the fog, minimizing reflective glare. Conversely, high beams are dangerous because they project light straight ahead, reflecting off airborne moisture droplets and blinding the driver. Driving with no lights is illegal in low visibility, and hazard lights are reserved for stopped or disabled vehicles, not active driving. For exam prep success, remember that low beams are the standard safety requirement for fog, heavy rain, and snow to ensure your vehicle remains visible to others.
