How should you react if another vehicle is approaching with bright high beams?

When another vehicle approaches with bright high beams, dimming your lights immediately is the appropriate reaction. This action helps to reduce glare and ensures that you do not blind the oncoming driver. High beams can significantly impair the vision of other drivers, making it difficult for them to safely navigate the road. By dimming your lights, you also follow the courtesy rule of sharing the road and maintaining safe visibility for everyone.

In addition, failing to dim your lights could result in a dangerous situation where both drivers struggle to see. Ignoring the bright high beams might not only be disrespectful but could also lead to a compromise of safety on the road as your visibility is affected. Speeding up is not a safe response, as it may increase the risk of an accident or loss of control. Maintaining proper lane discipline is always important for safety, but in this scenario, it does not directly address the issue of oncoming bright lights. Thus, dimming your lights is the most responsible and effective measure to ensure a safe driving environment for all.
