I have white smoke coming out of my exhaust pipe. It only comes out when the car it is running for a little while and as soon as I pull off in it white smoke comes out. It comes out when I am sitting at the light and when I pull off it comes. Could you tell me exactly whats causes the white smoke to come out the exhaust pipe?

Welcome to 2CarPros. White smoke is commonly caused by an engine that is burning coolant. Is it constant or does it only smoke for a short burst when you start off from a stop? It could be oil smoke as well if it's got a gray or bluish tint to the smoke.
Either way you need to do some simple checks to see which it is. These guides might help you tell if it's oil or water.
