Final answer:
Option 3. No Passing Zone signs indicate that you cannot see far enough ahead to pass safely due to potential oncoming traffic or limited visibility.
Step-by-step explanation:
Signs or lane markings that indicate a No Passing Zone tell you that you can't see far enough ahead to pass safely. This means that there could be oncoming traffic, a curve, or a hill where visibility is limited, and it would be unsafe to pass another vehicle regardless of the time of day or night. These signs are critical for road safety and help prevent accidents caused by unsafe passing maneuvers.
