In conditions of reduced visibility, what should a driver do?

Answer: C — Use low-beam headlights

Using low-beam headlights is important in conditions of reduced visibility, such as fog, rain, or snow, because they provide adequate illumination of the road and help you see obstacles and other vehicles more clearly. High-beam headlights can create a glare that hampers visibility in these situations, as the light reflects off mist, rain, or snow and can blind the driver. Low beams are designed to cast light in a way that enhances clarity without creating that dangerous glare, allowing for safer driving in adverse conditions. In addition, low beams enable oncoming traffic to see your vehicle more effectively, reducing the risk of collisions. This safety precaution is a crucial part of defensive driving, as it helps maintain awareness of the environment around you, ensuring you can react appropriately to any hazards that may arise.
