What is the recommended action when approaching dusk?

As dusk approaches, the natural light diminishes, making visibility more challenging for drivers. The recommended action is to switch to lower headlight beams. Using low beams is important because they provide adequate illumination without causing glare for oncoming drivers, which can happen when high beams are used in low-light conditions.

Additionally, low beams are designed to focus light closer to the ground and can illuminate road signs, pedestrians, and other potential hazards more effectively as darkness falls. This adjustment is particularly critical since visibility is reduced, and it’s essential to ensure you can see clearly while also allowing others on the road to see you without being blinded by bright lights.

The other options may not be suitable; for instance, using high beams can be hazardous due to bright glare that affects other drivers. Driving with fog lights on is generally meant for low-visibility conditions like fog or heavy rain, and opening windows does not improve visibility or safety while driving.
