The exhaust from a car's tailpipe containes, water, carbon, and fuel contaminants. When conditions are right, they can freeze on road surfaces and create what is called "black ice" Like regular water which freezes on road surface, (especially on bridges) creates a dangerous road condition. Black ice is more dangerous as it cannot always be seen, as it is darker in color and can blend in with the road surface.

I have known this to happen. It is the water vapor that freezes say you take many short trips then leave the car off for hours in sub freezing weather over several days. the ice slowely builds up until the car will not run.. I have heard it takes a twenty mile trip to completely dry the exhaust system.

The water vapour that you see from exhausts is hot, sometimes it condenses at the tail pipe and drips as water. Sometimes if you park on a cold day the small amount of water in the tail pipe can freeze, but would immediately melt when the car started and pushed hot exhaust gases through the pipe.

no it does not ,but the heat caused by the exhaust can create moister in the form of condensation that can freeze in really cold situations.not enough to restrict the exhaust flow .most gas and emissions that come from the system are non flammable inert forms of gas.

On an EXTREMELY cold day, the water vapour might, but the rest of it does not.
