If the driver of an approaching car fails to dim their lights, what should you do?

When driving at night, encountering an approaching car with their high beams on can create dangerous visibility issues. It's important to maintain focus on the road ahead to avoid being blinded by the oncoming headlights, which is why the first action to take is to keep your gaze directed towards the right side of the road. This helps in maintaining your awareness of the lane and any obstacles that might be present.

Additionally, flicking your headlight beams low and high serves as a signal to the other driver that their high beams are on, encouraging them to dim their lights. This can be a courteous way to prompt the other driver to adjust their headlights, ensuring better visibility for both parties on the road.

Therefore, combining these two actions—watching the road and signaling the other driver—is a comprehensive response to deal with the situation effectively.
