Final answer:
When driving in fog, it is important to have your headlights on. Specifically, you should use low-beam headlights or fog lights, as they provide a more focused and less reflective beam compared to high-beam headlights.
Step-by-step explanation:
When driving in fog, it is important to have your headlights on. Specifically, you should use low-beam headlights or fog lights, as they provide a more focused and less reflective beam compared to high-beam headlights. This helps to improve visibility in the fog by reducing glare and reflecting less light back at you.
Fog lights are specially designed to be mounted lower on the vehicle, closer to the road surface. This helps to illuminate the road directly in front of the vehicle, making it easier to see obstacles and other vehicles. Additionally, fog lights are designed with a wider and shorter beam pattern, which helps to improve visibility in conditions with limited visibility, such as fog, rain, or snow.
