At night, when driving, you should always:

Using high beams when there are no oncoming vehicles is a crucial practice for night driving, as it significantly enhances your visibility. High beams illuminate a greater distance ahead and the sides of the road, helping you to see potential hazards, pedestrians, and wildlife that may be on or near the roadway. This increased visibility allows for better reaction times in low-light situations, contributing to safer driving conditions.

On the other hand, using sunglasses at night is not effective, as they reduce overall visibility rather than enhance it. Similarly, utilizing your dome light may help you see your speedometer, but it can also reduce your night vision by making it harder to see outside the vehicle. High beams should be dimmed when other vehicles are approaching to prevent blinding other drivers, but they are beneficial when the road is clear, making this practice essential in ensuring both personal visibility and safety on the road.
