On a wet road, it will usually be most slippery:

• A. In the wheel tracks
• B. On the painted lines
• C. In the center portion of the lane
• D. On the edges

Answer: (C)

When pavement is wet, traction drops because a thin film of water reduces the grip between tire rubber and the road surface. The center portion of a lane tends to be the slickest because it is typically the smoothest, most worn area with little surface texture to grab a tire. Water tends to pool there and isn’t as easily shed as in the wheel tracks, which are grooves that help channel water away and provide slightly more grip. The edges may have rougher texture or debris, which can offer more traction than a smooth center, and painted lines can be particularly slick when wet. So, the center of the lane often presents the slickest patch on a wet road.
