When faced with bad weather, what is the appropriate action regarding headlights?

Answer: C — Switch to low-beam headlights

Using low-beam headlights in bad weather is crucial for safety and visibility. Low-beam headlights are designed to illuminate the road directly in front of your vehicle without causing glare for other drivers, which is particularly important in conditions such as rain, fog, or snow. High-beam headlights can reflect off precipitation, creating a blinding effect that reduces overall visibility instead of enhancing it. In addition, low beams provide a broader light pattern that is more effective for seeing the road and the immediate surroundings, which is essential for navigating through adverse weather conditions. Maintaining proper visibility without blinding others contributes to safer driving for everyone on the road during challenging weather.
