What does a single solid white pavement line marking indicate?

1. A passing zone

2. A no passing zone

3. Pedestrian right-of-way

4. Approaching an intersection

The correct answer is: A no passing zone

A single solid white pavement line marking indicates a no passing zone. This type of line is used to convey to drivers that they should not change lanes or pass other vehicles in that area. The intent is to ensure safety by preventing lane changes when visibility is limited or when it may be unsafe to do so. This line is commonly found in locations such as near intersections, on curves, or in areas where there are road hazards. In contrast, a passing zone would be marked by a dashed line, allowing drivers to overtake slower vehicles safely. Pedestrian right-of-way and intersections are typically indicated by different traffic control measures such as crosswalks or signage, rather than solid white lines. Therefore, understanding the context and meaning of road markings is crucial for safe driving practices.
