What is a safe practice when driving in fog?

Using low beam headlights when driving in fog is a safe practice because high beam headlights can actually worsen visibility in these conditions. Fog reflects light back, and the bright beam can create a glare that obscures your view rather than enhancing it. Low beam headlights provide a more controlled and focused light that cuts through the fog better, allowing you to see the road and other vehicles more clearly.

In adverse weather conditions, maintaining visibility is critical for safe driving. Using low beams helps you to see the road immediately ahead while reducing glare. Emergency flashers are intended to warn others that your vehicle is stationary or operating under abnormal conditions, but they do not help you see the road better. Additionally, driving at or above the speed limit is unsafe in fog, as visibility is reduced and stopping distances increase. Therefore, opting for low beam headlights is the most effective strategy for navigating fog safely.
