Vehicle and Traffic Law of NY state (2014) in Title 3, Article 9, Section 375-12-b state that a vehicle's rear window can be covered with opaque material as long as that vehicle has two side view mirrors on both sides of the car which allow the driver to see the road behind the vehicle. There was snow on my rear window, but my vehicle has side view mirrors. All other windows were clear of snow. Am I guilty of an obstruction of view charge or am I within the parameters of the law. I believe that I was driving legally per my interpretation of the NYS Vehicle and Traffic Law.
