What should be done when visibility is impaired at night due to rain?

When visibility is impaired at night due to rain, driving with caution and using low beams is the safest approach. Low beams provide adequate illumination of the road without causing glare that can further reduce visibility for both the driver and other road users. Driving at a slower speed also allows for better reaction time to any hazards that may arise, such as puddles, debris, or other vehicles. Rain can create slippery road conditions, so maintaining a safe distance from other vehicles is crucial.

Using high beams in these conditions is not advisable, as they can reflect off the rain and create a blinding effect that hampers visibility even more. Similarly, fog lights are specifically designed for low-visibility conditions like fog, not heavy rain, and may not be effective in these circumstances. Speeding up to cross the area quickly can lead to loss of control or accidents, as it does not address the compromised visibility and could increase the risk of encountering unexpected road conditions.
