Where are sand and gravel most likely to collect on a paved two-lane road?

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

Answer: (B)

When sand and gravel are present on a paved road, they tend to accumulate where the water and wind push debris toward the edge—the sides of the road. Roads are crowned to shed water to the verge, and loose particles are carried by runoff and wind toward the shoulder, where they settle. The center of the lane stays relatively cleaner, so the material ends up beside the travel path rather than in the middle. For riders, gravel near the edge can catch you by surprise, so slow down and ride smoothly if you encounter it.
