West Virginia Motorcycle Permit Practice Test

The most slippery area on a wet road is typically in the center portion of the lane. This is because the center of the lane often collects the most water due to the road's crown and the way water drains from the surface. When it rains, the oils and debris that have accumulated on the road surface can mix with water, particularly in the center where vehicles travel most frequently. This combination can create a thin layer of slick material that significantly reduces traction for motorcycles and vehicles. While the edges of the lane may also be slippery, they generally do not accumulate the same amount of water and debris as the center does. Shoulders are often designed to facilitate drainage away from the roadway, which makes them less slippery compared to the lane center. Traffic intersections can be slippery, primarily due to stopping and starting traffic, but they are designed to manage water flow better than the center of the lanes. Thus, focusing on the center portion of the lane provides the best understanding of where the greatest hazard lies on wet roads.
