Which of the following describes no-passing zones accurately?

• A. They allow passing only during daylight hours.
• B. No-passing zones require you to pass on the left if safe.
• C. No-passing sign indicates you are not allowed to pass other vehicles in that area.
• D. They apply only to trucks.

Answer: (C)

No-passing zones indicate you are not allowed to pass other vehicles in that area. These stretches are chosen because sight distance or road conditions (like hills, curves, or intersections) make passing dangerous. The sign communicates a universal rule for all drivers and at all times, so you should stay in your lane and avoid starting or completing a pass within the zone. This applies to every vehicle, not just trucks, and it isn’t limited to daylight hours.
