[OAdelyn]

When driving in foggy conditions with 200 meters of visibility, vehicles should maintain a distance of at least 100 meters from the vehicle ahead in the same lane. Below are some precautions for driving in foggy weather: 1. Proper use of lights: When driving in fog, drivers should turn on both front and rear fog lights. If the fog is extremely heavy, hazard lights can also be activated. The main purpose of turning on fog lights and hazard lights is to make your vehicle more visible to other drivers, helping to prevent rear-end collisions or side-swipe accidents. 2. Pull over when necessary: If heavy fog suddenly appears and you don't have time to reach the nearest service area, you should pull over to the emergency stopping lane of the highway as soon as possible while turning on your fog lights, width indicators, and tail lights. Additionally, place a warning sign at least 150 meters away in the direction of approaching traffic.
