Which vehicle light is recommended to use when driving in fog?

Answer: C — Dipped headlights

Using dipped headlights in foggy conditions is recommended because they provide adequate illumination of the road without causing excessive glare. Fog can reflect light back towards the driver, making visibility worse if high beams or other bright lights are used. Dipped headlights create a lower intensity light that allows for better visibility of the road directly ahead and helps other road users see your vehicle as well. In fog conditions, the goal is to enhance your visibility while minimizing the risk of blinding yourself or other drivers. Unlike high beam headlights, which can create a wall of light that reflects back in fog, dipped headlights cut through the fog more effectively. This helps you see the road surface and any obstacles while also making your vehicle more visible to others. The other options are less effective for various reasons. Park lights are not bright enough for driving in fog, while front and rear fog lights are sometimes used depending on regulations and visibility; however, they are not always the primary recommendation in fog compared to dipped headlights.
