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

Sand and gravel are most likely to collect near the sides of the road due to several factors. Roads are often constructed with a slight crown, which means the surface is slightly higher in the center and slopes down towards the edges. This design helps with rainwater drainage, but it also causes debris, including sand and gravel, to naturally accumulate along the sides where the water runs off.

Additionally, vehicles tend to push loose materials towards the edge of the roadway as they pass. The areas near the shoulders are less disturbed by tire traction compared to the central lane, making it a common point for debris to settle. Therefore, recognizing this tendency is crucial for motorcyclists, as riding in these areas increases the risk of losing control due to the unstable surface. Staying aware of where sand and gravel collect can help riders make safer choices when navigating turns and changing lanes.
