The 21-year-old also faces charges of assault by auto and leaving the scene of a dangerous accident.
Friday night's crash injured nine people near the new Meadowlands Stadium.
The victims, including a 20-month-old child, were treated at two area hospitals and all are expected to recover. They were crossing Route 120 when they were struck just before midnight.
Morocho was later found in Wallington.
He declined comment after the hearing.
