When is it legal to pass another vehicle on a two-lane road?

• A. Only when the center line is solid and it is safe to pass.
• B. Only when the center line is dashed and it is safe to pass without interfering with oncoming traffic.
• C. Whenever you feel impatient behind the vehicle ahead.
• D. Never; passing is prohibited on two-lane roads.

Answer: (B)

On a two-lane road, you may pass only when the center line is dashed and you can do so safely without interfering with oncoming traffic. A dashed line means passing is allowed if the way ahead is clear. A solid line means passing is not allowed. Impatience isn’t a valid reason to pass; you must follow the road markings and ensure there’s enough distance and visibility to complete the pass safely.
