When driving in foggy conditions, what should you use for visibility?
Answer: B — Low beam headlights
In foggy conditions, it is important to use low beam headlights for visibility. High beam headlights should not be used as they will reflect off the fog and reduce visibility even further. Emergency flashers are intended for signaling an emergency and should not be used while driving. Driving lights are used primarily for off-road driving and are not recommended for use in foggy conditions. Therefore, low beam headlights are the most appropriate choice for driving in foggy conditions.
