Which situation would require the use of lower beam headlights during the day?

Using lower beam headlights during the day is crucial in certain situations to ensure visibility and safety. When meeting other vehicles, it is important to use lower beam headlights to reduce glare for oncoming drivers. This helps to prevent accidents as high beams can blind other motorists, making it difficult for them to see the road ahead.

In conditions such as heavy rain, while parked on the side of the road, or when driving in rural areas, the usage of headlights can vary but does not necessarily require the use of lower beams. For instance, in heavy rain, while you could use your headlights for visibility, lower beams are more beneficial than high beams to avoid reflecting light off the rain. When parked on the side of the road, headlights may not need to be on at all unless visibility is particularly poor. In rural areas, while it's essential to have lights on for visibility, the context matters; lower beams are typically required when being approached by or meeting other vehicles to ensure safety.
