Which statement best describes safe headlight use in poor visibility?

• A. Low beams should be used at night, in poor visibility, and in city; high beams are for dark rural roads with no other traffic.
• B. High beams should be used in city streets at all times.
• C. Headlights are optional in rain.
• D. Use high beams in fog.

Answer: (C)

When visibility is poor, making yourself seen and seeing the road clearly is the priority. Turning on headlights helps others notice you sooner and helps you spot hazards earlier. In rain or fog, low beams are the right choice because they illuminate the road without causing glare. High beams shine farther but reflect off moisture and can blind oncoming drivers and yourself, which makes them dangerous in these conditions. In city streets with traffic, you want to avoid the glare that high beams create for others, so staying with low beams is safer. High beams are better reserved for dark, rural roads with no other vehicles around.

The statement that headlights are optional in rain doesn’t align with safe driving practice, since using headlights in poor visibility improves visibility for you and for other drivers. The other options either promote unsafe high-beam use (in fog or in traffic) or misstate when headlights are needed. The key takeaway is: in poor visibility, use headlights, and prefer low beams in rain and fog; reserve high beams for isolated, dark roads.
