N.J. Stat. § 48:4-2.1h
In addition to any other penalties provided by law, when a bus is operated on public highways or in public places in this State, with a bus safety out-of-service violation, whether in interstate or intrastate commerce, whether registered or not in this or any other jurisdiction, that vehicle may be immediately placed out-of-service and held or impounded by law enforcement authorities or the department. The vehicle may be held or impounded until appropriate repairs are made on-site or until towed by the owner or operator to an appropriate repair facility, maintenance garage or otherwise, so that repairs of all bus safety out-of-service violations can be made. The vehicle shall not be operated in this State until the defects are remediated and such remedial action is either certified or approved by the department.
