This bill amends New Jersey's motor vehicle laws to allow certain vehicles owned and operated by the State or local government units, specifically those used for snow removal or road salting, to display both amber and green warning lights. Previously, these vehicles were restricted to using only amber lights for warning signals. The new provision permits the addition of green lights, but they can only be activated when the vehicle is engaged in operations that pose a traffic hazard requiring unusual care from other drivers. Additionally, the vehicle must also display the required amber lights during such operations.

The bill also makes several amendments to existing laws regarding the approval and specifications of warning lights. It changes the authority from the "Director of the Division of Motor Vehicles" to the "Chief Administrator of the New Jersey Motor Vehicle Commission" for the approval of warning lamps. Furthermore, it clarifies the conditions under which vehicles may display lights of different colors, including the new provision for green lights, and establishes a fee structure for permits related to the use of non-standard lighting on vehicles. The bill is set to take effect immediately upon passage.
