NJ Transit and its bus drivers are held to the same negligence standard under the TCA as other common carriers -- to exercise the utmost caution to protect their passengers as would a very careful and prudent person under similar circumstances. See N.J.S.A. 59:2-2(a), :3-1(a). None of the TCA immunities defendants asserted abrogated their common-carrier duty to protect Maison from the dangerous and threatening conduct of the teenage passengers. The TCA leaves no doubt that an allocation of fault between a negligent public entity and its employee and an intentional tortfeasor is mandated. See N.J.S.A. 59:9-3.1. Nevertheless, to ensure that defendants’ duty to protect their passenger is not unfairly diluted or diminished, the trial court must give the jury clear guidance on the factors to consider in allocating degrees of fault. See Frugis v. Bracigliano, 177 N.J. 250, 274-75, 281-83 (2003).
