Dring A Rain Shower The Road Surface is likely to be most slippery?

During a rain shower, the road surface is likely to be most slippery when the rain first begins. This is because the initial rainfall mixes with oil and debris on the road, creating a slick layer. As the rain continues, the water can wash away some of these contaminants, making the surface less slippery over time. Therefore, caution is advised during the first few minutes of rain.
