My vehicle did not start.

I was on high speed and I noticed that smoke was coming out of the front hood and i parked to check. I saw oil splashed all over the engine and I tried to look for where the leakage came from but I could not. I tried to drive to a safe place which I finally parked. I gauged my oil but the engine oil was low. I topped the oil to move ahead but the the engine refused to start. When I turn on the engine to start,the engine will not crank but all the light indicator was on.
