Why does my car smoke when I start it in the morning?

Your car must produce smoke as a byproduct of the engine combustion process (burning of the fuel air mixture). Blue smoke is often caused by broken piston rings or damaged valve stem seals which allow engine oil to infiltrate the combustion chamber and get burnt with the fuel air mixture.

How the vehicles are emitting smoke?
