The police are in a difficult situation because they want to limit their exposure to people who may have the virus or carrying it. Therefore, you may notice that most police are using their discretion to let minor infractions go. That means if you have something hanging from your rear view mirror, you may not get pulled over. Maybe your headlight is out right now, that may be overlooked as well. Technically, almost all of Title 39, is discretionary. Title 39 is the New Jersey code that lists all of the motor vehicle violations you could be charged with.
Keeping this all in mind, now is not the time to break the law. If you are given a traffic ticket, the good news is municipal courts in New Jersey are currently closed. No one knows how long that will extend to. When they are up and running, you will have to appear in court with everyone else. No one needs to be one of the first few to attend a court hearing once the courts open and risk infection.
Additionally, the police are still arresting people for major violations of the law. If arrested on a complaint warrant, that means you are going to jail until an assessment is performed. Do you really want to be housed in close quarters with God knows who while a virus outbreak is happening! My suggestion is to keep acting like a law abiding citizen.
