Detailed Solution

Both reason and assertion are true, and the reason is the correct explanation of assertion.
Assertion: A car will skid more on a wet road than on a dry one because the dry surface and the automobile tyres have more friction. Friction is a force that keeps two surfaces from moving relative to one another.
Reason: To put it simply, when you drive, the engine exerts a force on the driving wheels, propelling the vehicle forward. Friction is the force that prevents the tyre rubber from sliding on the road surface. This explains the skidding of cars on a wet road and hence, is true.
