How should you respond to a vehicle that is flashing its high beams at you?

When a vehicle is flashing its high beams at you, it is typically a signal that there is a potential hazard ahead, or that you are using your high beams and should switch to low beams to avoid blinding oncoming traffic. Dimming your headlights, which means switching from high beams to low beams, is the appropriate and responsible action to take.

By dimming your headlights, you reduce glare for the driver coming towards you, making it safer for everyone on the road. This action demonstrates good driving etiquette and ensures that visibility is maintained for both you and oncoming vehicles, especially at night or in low-light conditions.

Other responses, such as flashing your high beams back, could create confusion or escalate a situation unnecessarily. Ignoring the signal would also disregard an important communication about road safety, and adjusting your mirrors does not directly address the immediate concern of potential glare or hazard that the flashing lights are indicating.
