There's a fundamental and elementary rule of physics: frozen water, aka ice, has a very low coefficient of friction. [1] The coefficient of friction depends on the material of the objects in contact; for example, metal on ice has a low coefficient of friction (they slide past each other easily) whereas an automobile tire on tarmac has a higher coefficient.
Now, tires on ice are another matter; acceleration comes into play and a mess is often the result, especially with unexperienced or non-thinking drivers.
An example:
Think, people, before you drive on ice.
[1] The coefficient of friction is a dimensionless value of scale that describes the ratio of the force of friction between two bodies and the force pressing them together.
