What should you do when driving in foggy conditions?

When driving in foggy conditions, using low beam headlights is the appropriate action. Low beam headlights are designed to provide adequate illumination without causing a glare that would reflect off the fog, rain, or snow, which can make visibility even more difficult. In contrast, high beam headlights can reflect back and blind you as well as other drivers, significantly hampering visibility.

Driving at the speed limit in foggy conditions is often not advisable, as it may not account for the reduced visibility and the potential need to drive more slowly to maintain safety. Finally, while pulling over and stopping can sometimes be necessary, especially if visibility drops to near zero, it should not be considered a primary option as a response to fog. Instead, if you must stop, finding a safe, designated area away from traffic is critical. Thus, using low beam headlights is the most effective method to improve your visibility while driving in fog.
