N.J.S.A. 2C:11-5.1 applies to the act of fleeing from the scene of an accident. The number of fatalities that may result from the accident is not an element of the offense and thus only one count of the offense may be charged per accident, regardless of the number of victims. Although the Appellate Division correctly reversed the trial court’s judgment with regard to the number of counts that could be charged, the appellate court should have remanded the case to the trial court to permit the parties to negotiate a new plea agreement or go to trial rather than amend the sentence in a manner not contemplated by the plea agreement.
