What is a critical action to take during a nighttime drive when facing bright lights?

Looking at the right edge of the road is a critical action to take during nighttime driving when faced with bright lights, such as oncoming headlights. This technique helps reduce the blinding effect of the bright lights by directing your focus away from the source of the glare. It allows your eyes to maintain their night vision and helps you stay oriented on the road.

Focusing on the right edge provides reference points for positioning your vehicle safely on the road, aiding in navigation and avoiding potential hazards. This technique is especially useful if other vehicles are approaching with high beams or if you are driving in poorly lit conditions.

The other choices, such as closing one eye or looking straight ahead, do not mitigate the blinding effects and can lead to impaired visibility. Turning on high beams in the presence of oncoming traffic is also not advisable, as it can increase glare for other drivers, creating a dangerous situation on the road.
