On a paved two-lane road, sand and gravel are most likely to collect

• A. Near the center line
• B. Near the sides of the road
• C. In the middle of the lane
• D. Near intersections

Answer: (B)

Road surfaces are crowned in the middle to shed water toward the sides, so loose material naturally moves toward the edges. Rain, runoff, and gravity pull sand and gravel down to the shoulder, and tires or maintenance work tend to push debris toward the outer edges rather than the center. Because of this, sand and gravel collect most where the road meets the shoulder — along the sides rather than in the center or at intersections. This creates a slicker edge surface, so riders should stay aware of debris and, when possible, avoid riding right along the edge.
