What does a no-passing sign indicate?

• A. You may pass other vehicles.
• B. The road ahead has two lanes in the same direction.
• C. You should pass only on the dotted lines.
• D. Do not pass other vehicles.

Answer: (D)

A no-passing sign tells you that you are entering a stretch where overtaking other vehicles is not allowed. This restriction is placed where visibility is limited or road conditions make passing dangerous—like on curves, hills, or near intersections. When you see it, stay in your lane and follow the vehicle in front at a safe distance; do not try to pass. You can pass again only after you reach the end of the no-passing zone, which is shown by the end sign or by road markings that indicate passing is allowed (such as a change from a solid to a dashed centerline). If you’re unsure, err on the side of caution and wait until it’s clearly legal and safe to pass.
