When driving at night, what should you use to improve visibility near the edges of the road?

Using high beam lights at night is the best choice for improving visibility near the edges of the road. High beams provide a stronger light output, illuminating a greater distance ahead and helping drivers see beyond the reach of low beams. This can be particularly beneficial on dark, rural roads or in areas with little ambient light, allowing for better detection of pedestrians, animals, and road signs.

However, it is important to switch to low beam lights when approaching oncoming traffic or when following another vehicle to prevent blinding other drivers. Low beam lights are designed to minimize glare while still providing adequate visibility, making them a safer choice in those situations. Fog lights are useful in conditions of reduced visibility, such as fog or heavy rain, but they don’t typically enhance side visibility to the same extent as high beams. Parking lights are intended for use when a vehicle is parked and should not be relied upon for driving visibility.

Thus, high beam lights stand out as the most effective tool for improving visibility on dark roads when there are no oncoming vehicles present.
