Within what distance should you not pass another vehicle when approaching a hill or curve?

1. 1/4 mile

2. 1/2 mile

3. 1/3 mile

4. 2/3 mile

The correct answer is: 1/3 mile

When approaching a hill or curve, the appropriate distance to avoid passing another vehicle is typically around one-third of a mile. This distance is crucial because visibility is often limited in these areas. Hills and curves can obstruct your view of oncoming traffic, making it unsafe to try to pass another vehicle. If you cannot see clearly ahead, you may not be aware of any obstacles or vehicles coming towards you, increasing the risk of a collision. Understanding this rule promotes safe driving practices and emphasizes the importance of ensuring clear sightlines before making any maneuver that could endanger yourself or others on the road. Recognizing the danger of attempting to pass in areas with restricted visibility helps reinforce overall traffic safety.
