Before attempting a pass on a two-lane highway, you should check for oncoming vehicles.

• A. There must be no oncoming traffic
• B. If vehicles are approaching
• C. The weather is clear
• D. You have plenty of time

Answer: (B)

The essential idea is that passing on a two-lane highway must be done only after you’ve confirmed there’s no oncoming traffic within a safe distance and you have enough time to complete the maneuver and return to your lane. The best option emphasizes actively checking whether vehicles are approaching; if there are approaching vehicles, you should not attempt the pass. Weather or time won’t by themselves make passing safe, and even if conditions seem favorable, you still need a clear opposite-lane view and sufficient space to finish the pass before any oncoming vehicle arrives.
