What should you do if another oncoming vehicle turn off their high beams?

If another oncoming vehicle turns off their high beams as a courtesy, it is polite to return the gesture and switch off your own high beams as well. This creates a safer driving environment for both vehicles by reducing glare and potential distractions, making it easier for each driver to see the road ahead more clearly. By dimming your lights, you show consideration for the other driver and ensure a more comfortable and cooperative driving experience.
