What should a driver do during low visibility conditions?

Answer: C — Reduce speed and use low-beam headlights

During low visibility conditions, it is essential for a driver to reduce speed and use low-beam headlights. Reducing speed is crucial because it allows for better reaction time in case of unexpected obstacles or changes in the road conditions. When visibility is compromised—due to fog, rain, or darkness—driving at normal speed can significantly increase the risk of accidents, as drivers may not see hazards or other vehicles in time to react appropriately. Using low-beam headlights is important in these conditions as well. High-beam headlights can create glare in fog, rain, or snow, which can make it even harder to see. Low-beam headlights provide adequate illumination of the road immediately in front of the vehicle without causing excessive glare, helping to navigate safely and clearly. This combination of reducing speed and using low-beam headlights helps ensure the driver's safety and the safety of others on the road during low visibility conditions.
