Using low beams when driving in fog is the recommended action because high beams can create more glare and reflect off the fog, making visibility even more difficult. Low beams provide a more directed light that can penetrate the fog better and help illuminate the road without causing excessive reflection.

Driving at maximum speed is ill-advised in foggy conditions, as reduced visibility can lead to dangerous situations. While turning on hazard lights can signal to other drivers that you're having trouble, it doesn't enhance your visibility to see the road ahead. Therefore, using low beams is the safest approach to maintain visibility and control while navigating through foggy weather.
