Which type of lights should you use when driving in fog?

Answer: C — Low beams or fog lights

Using low beams or fog lights while driving in fog is essential because these lights are designed to illuminate the road directly in front of your vehicle without causing too much glare. Fog can reflect light back at the driver, making it difficult to see. High beams can create a white wall effect, intensifying the fog’s glare and reducing visibility rather than improving it. Regular headlights may not provide enough illumination directly in front when conditions are poor, and hazard lights are intended for situations where you need to alert other drivers of a stopped or slow-moving vehicle, rather than for enhancing visibility when driving. Fog lights, combined with low beams, ensure maximum safety and clarity when navigating through foggy conditions.
