Explanation
When rain starts to fall, the road surface can become very slippery due to a combination of factors. Oils, dust, and road film that have accumulated on the road's surface mix with the rainwater, creating a slippery layer. This is especially pronounced during the first half hour of rainfall because the water doesn't immediately wash away the dust and road film. The mixture of oil, dirt, rubber dust, and water creates a slick surface that reduces tire traction and makes it harder to maintain control of the vehicle.
