You are making the mistake of describing things we cannot see. And your spelling will get you rejected by a reader immediately.
JAMES SMITH, 17, walks slowly into a bar, with a vacant expression. He has been in a car accident, his varsity jacket is torn and bloody, blood drips down his face from a forehead cut.
Leave out the indirection (one hell of a bad driver), leave out any humorous asides like a smiley face, do not reference "the accident" if you have not shown an accident in the previous scene. The prose is not a conversation between you and the script reader, it is a description of what the viewer sees, period.
Be concrete and literal, it is filmable. "drifting" into a bar is poetic, but you can't film it unless he is a ghost or weightless in space. "Walking slowly" is something the actor can do, James is stunned. "He has been in a car accident" is something the makeup department knows how to do. The specifics of the torn jacket and blood are for them too, and indicate the severity of the accident.
