The correct answer is that you should use your headlights during the day when visibility is seriously reduced. This scenario includes conditions such as fog, heavy rain, or snow that significantly impair your ability to see other vehicles and obstacles, as well as make it harder for others to see you.

Using headlights in reduced visibility improves safety by enhancing the visibility of your vehicle to others on the road, which is crucial in conditions where natural light is insufficient. It's important to remember that while headlights are typically used at night, their usage is equally vital during daylight hours when weather conditions warrant it.

In contrast, using headlights only in fog or rain is too restrictive, as visibility can be compromised in a variety of other situations as well. Maintaining good visibility during the day is essential for safe driving regardless of the specific conditions. Additionally, while driving on the motorway or in the city may have lighting conditions that vary, it is the specific situation of seriously reduced visibility that mandates the use of headlights as a safety measure.
