What is the purpose of no-passing zones with painted lines?

• A. They indicate areas where passing is prohibited due to restricted view or potential hazards.
• B. They indicate areas where passing is allowed with caution.
• C. They indicate school zones only.
• D. They indicate a speed limit zone.

Answer: (D)

No-passing zones marked with painted lines are there to keep you safe in places where you can’t see oncoming traffic or where there are hazards. When your side shows a solid line, passing is prohibited because a driver cannot safely judge the distance and speed of vehicles coming toward you, such as on curves, hills, or near intersections. You should stay behind the solid line and only pass where the lines become dashed and it’s clear you have enough sight distance and time to do so safely. These lines aren’t about school zones or speed limits; those are shown by separate signs and markings.
