What is a safe driving practice when encountering a foggy condition?

Answer: C — Use low-beam headlights for better visibility

Using low-beam headlights in foggy conditions is crucial for maintaining visibility while driving safely. High-beam headlights can create a glare that reflects off the fog, reducing your ability to see and making it more difficult for other drivers to see you. Keeping headlights off is not advisable, as it severely limits visibility, which increases the risk of collisions. Driving at high speeds during fog can be dangerous due to the reduced visibility and the increased likelihood of losing control of the vehicle. Low-beam headlights are specifically designed to provide better illumination of the road directly in front of you without causing excessive glare, which is essential in foggy conditions where visibility is limited. They penetrate the fog more effectively than high beams, allowing for safer navigation through reduced visibility.
