The water eventually evaporates.
The average coefficient of friction for a dry road is typically around 0.7-0.8. This means that the frictional force between tires and the road surface is 70-80% of the normal force pressing the tires onto the road.
The water is shiny, your head lights reflect as if it were a mirror so absence of light is black. Day time has the same answer with the exception that driving into the sun is like driving into a laser beam.
A dry road typically has less friction than a wet road. Water on the road surface can reduce tire grip, leading to an increase in friction and longer stopping distances. The lower friction on wet roads can increase the risk of skidding and losing control of the vehicle.
Coefficient of friction on raod and a tire varies depending on the condition of the road and tyre Wet Road: 0.4 Dry Road: 0.7 This is the average coeffecient for these conditions again it can vary
Oil on the road creates rainbow patterns in rain puddles because of thin film interference. When light hits the oil slick, it reflects off both the top of the oil and the road's surface. The varying thickness of the oil causes interference, resulting in the colorful patterns seen in the puddle.
The water remains of the surface of the road and thus is able to evaporate quickly when the rain stops and the sun comes out.

The curvature made the rain drain to the sides of the road.
Yes. There is less frictional force between the car tyres and a wet road surface than with a dry road surface.
As rain falls, the water mixes with oil found on the road's surface, making the pavement slippery.that we use the alakalis to the litmus paper
Rain is a type of precipitation, a product of the condensation of atmospheric water vapour that is deposited on the earth's surface. It forms when separate drops of water fall to the Earth's surface from clouds. Not all rain reaches the surface; some evaporates while falling through dry air. When none of it reaches the ground, it is called virga, a phenomenon often seen in hot, dry desert regions.
In ideal conditions, dry weather, great road surface etc. slick tyres offer more rubber to the road therefore greater traction. Normal road tyres are a compromise, on any one trip your car may have to cope with sunshine, rain, sleet, snow, bad road surface, smooth surface, mud, and gravel. Manufacturers have to make a tyre that can cope with that. The result is the tyre on your car.

The average coefficient of friction for a dry road is typically around 0.7-0.8. This means that the frictional force between tires and the road surface is 70-80% of the normal force pressing the tires onto the road.
The road is most slippery during the first half hour of the rain (C) because the rain mixes with the oil and dirt on the road, making it more hazardous for driving. After a long rain (A), the water washes away some of the oil and dirt, reducing the slipperiness of the road. A new road (B) typically has better traction due to the roughness of the surface.
Accumulated oil residue from the traffic flow during dry weather becomes wet and moves to the surface of the travelled lanes because oil is lighter than water. This makes the road surface extermely slippery.
