When driving at night with high beams on, when should you switch to low beams before meeting oncoming traffic?

The correct choice is based on the guideline that when driving at night with high beams, you should switch to low beams when you are about 500 feet away from oncoming traffic. This distance ensures that you do not blind or distract the other driver, making it safer for everyone on the road. High beams can significantly illuminate the road ahead, but they can also impair the vision of drivers approaching from the opposite direction. By dimming your lights ahead of time, you provide those drivers with a clearer view and maintain overall safety.

In addition to preventing glare for oncoming vehicles, this practice helps you comply with traffic regulations, as it is a recommended safety measure. It is important to be proactive in switching to low beams well in advance to minimize sudden changes that could catch oncoming drivers off guard.
