What should you do if the headlights of an oncoming vehicle prevent you from seeing ahead?

Answer: B — Look down and to the right of your lane

When encountering headlights from an oncoming vehicle that impair your visibility, the appropriate action is to look down and to the right of your lane. This technique helps to avoid direct glare from the oncoming headlights, which can temporarily blind you and hinder your ability to see the road ahead. By focusing on the right side of your lane, you can still maintain awareness of the road boundaries and any potential hazards while safely navigating the situation. The other choices do not address the reality of driving safely in such conditions. Closing your eyes and hoping for the best is not a practical or safe strategy, as it does not allow you to maintain control of the vehicle. Speeding up to get past the vehicle might increase the risk of losing control or colliding with other cars or obstacles in the environment. Using high beams in response to oncoming headlights is also inappropriate and could further blind or distract the other driver, creating a dangerous driving scenario. Thus, looking down and to the right provides the best combination of safety and situational awareness.
