Just at freezing
That is called black ice. It is a thin layer of transparent ice that forms on road surfaces when the temperature is near freezing, making it difficult to see and extremely slippery.

The mineral commonly used for melting ice on slippery winter surfaces is rock salt, also known as sodium chloride. It lowers the freezing point of water and helps to break down the ice, making it easier to clear the surface.
Using warm water to remove ice and snow may cause refreezing and create more slippery conditions. It's better to use salt or ice melt to break up the ice and snow first, then shovel it away.
A dry road is most slippery right after it starts raining. Of course any road is most slippery when it is covered in ice.
Ice becomes more slippery at 0 Celsius because at this temperature, a thin layer of water forms on the surface of the ice due to heat energy from friction created by pressure when walking. This layer reduces the friction between the ice and the object (like a shoe sole) making it more slippery. At -10 Celsius, this layer of water is less likely to form as the ice remains colder, providing more friction and making it less slippery.
The highways are most slippery when ice covers the surface. They are also very slippery at the beginning of a rain, where the oils on the road are brought up from the moisture, but not yet washed away by the rain.
during the day
The outside temperature is at or below the freezing point , so there might be ice on the road surface that makes it slippery
the ice rink is very slippery
is most slippery in the winter because of black ice and in the morning when the temperature is actually bit close to freezing because black ice forms along with slush in the morning so yes in the morniing slow down and watch out for snow, rain, anything weather wise that can affect your tires traction with the road is a threat. Remember if you skid always skid in the direction of the skid.

it melts the ice into water.
So they are able to slide on the ice. If they did not have a slippery body, getting onto ice would be tricky but moving on it would be hard.
