What should you do if an oncoming vehicle is approaching with high beams on?

Answer: B — Look toward the right edge of your lane

When an oncoming vehicle approaches with its high beams on, it can create a blinding effect that affects your ability to see clearly. Looking directly at the vehicle can impair your vision further and make it difficult to judge distance and speed. However, looking toward the right edge of your lane helps you maintain your lane and stay oriented on the road while minimizing the glare from the oncoming lights. This allows you to continue driving safely without being distracted by the bright lights. Switching your headlights to high beams is not advisable because it can further exacerbate the glare for both you and the oncoming driver. Additionally, driving off the road is extremely dangerous, as it can lead to loss of control or encountering obstacles that can cause an accident. Thus, looking toward the right edge of your lane is the safest response in this situation.
