What should you consider if you encounter fog while driving?

Answer: C — Drive with low beam headlights and reduce speed

When driving in fog, one of the most critical aspects to ensure safety is adapting your vehicle's speed and illumination appropriately. Using low beam headlights is essential because high beams can cause light to reflect off the fog, creating glare and making it even harder to see. Reducing your speed allows for increased reaction time in case of sudden obstacles or changes in the driving conditions, as visibility can be significantly impaired. Maintaining a manageable speed in fog ensures that you can stop or navigate in a controlled manner, minimizing the risk of accidents. This combination of using low beams and reducing speed helps enhance visibility and control, making it the safest option when encountering foggy conditions.
