45 . Why are roads especially slippery right after it begins to rain?
Tires are not usually designed to drive in rain.
In rainy weather, roads are often at their most slippery when the rain first begins to fall. Fresh rainwater mixes with oil and grease on the road to form a slick film. As the rain continues, this mixture will eventually wash away.
