This bill amends R.S.39:3-54 to allow certain motor vehicles, specifically those owned and operated by the State, bi-state or interstate governmental agencies, or local government units, to display both amber and green warning lights when engaged in snow removal or road salting operations. Previously, these vehicles were restricted to using only amber lights for warning signals. The new provisions stipulate that green lights can only be displayed when the vehicle is involved in activities that pose a traffic hazard requiring unusual care from other drivers, and the vehicle must also display the required amber lights.

Additionally, the bill updates the language regarding the approval authority for warning lights, changing references from the "Director of the Division of Motor Vehicles" to the "Chief Administrator of the New Jersey Motor Vehicle Commission." It also clarifies that vehicles contracted by the Department of Transportation for snow and ice management are permitted to use green lights alongside amber lights under the specified conditions. The bill aims to enhance safety on roadways during hazardous conditions by providing clearer warnings to approaching drivers.
