What is the best practice when an oncoming vehicle has its high beams on?

Answer: C — Look at the dotted line to the left side of the road

The best practice when encountering an oncoming vehicle with its high beams on is to look at the dotted line to the left side of the road. This is a safety measure designed to prevent temporary blindness from the intense light of the high beams. By focusing on the left side of the road, drivers can maintain their lane positioning and spatial awareness without being distracted or disoriented by the glare coming from the other vehicle. Looking directly at the oncoming vehicle may lead to a loss of night vision, causing difficulty in judging distance and speed, which can result in decreased reaction time. While some might think to look at the right side of the road, it’s less effective in centering your view in the lane. Ignoring the oncoming vehicle is also not advisable since maintaining awareness of surrounding traffic is crucial for safe driving, especially at night. Therefore, directing attention to the left-side dotted line effectively combines safety with continued lane management.
