What is the recommended action when driving in foggy weather?

When driving in foggy weather, increasing the following distance is crucial for safety. Fog can significantly reduce visibility, making it challenging to see other vehicles, obstacles, or changes in the road conditions. A greater following distance allows drivers more time to react to sudden stops or emergencies involving the vehicle in front. This buffer zone is essential in fog, where stopping distances can be extended due to reduced visibility.

In addition, while it is often tempting to drive at the speed limit, the actual safe speed in foggy conditions may be lower than the posted limit. This is due to the decreased visibility and increased stopping distance required on wet or slippery roads.

Using high beam headlights is not advisable in fog, as they can reflect off the fog droplets and create a glare that further impairs visibility. Instead, low beam headlights are recommended for foggy conditions, as they illuminate the road directly in front of the vehicle without causing excessive glare.

Turning off all lights is also unsafe, as it would make the vehicle nearly invisible to others, increasing the risk of accidents. Proper visibility both for the driver and other road users is key to navigating safely in fog.
