What is the best driving technique when driving in foggy conditions?

Drive at a higher than normal speed
Use your high beam headlights to light up the fog
Slow down and increase your following distance
Stop until the fog clears up

The correct answer is: Slow down and increase your following distance

Driving at a higher than normal speed in foggy conditions can be extremely dangerous as visibility is reduced and other drivers may not be able to see you in time to avoid a collision. Using your high beam headlights may seem like a good idea to increase visibility, but in reality, this can create glare and make it even harder to see. Stopping on the side of the road until the fog clears up is not recommended as this can also pose a potential hazard to other drivers. The best technique when driving in foggy conditions is to slow down and increase your following distance, allowing more time to react to potential hazards on the road.
