Does careless driving always require a court appearance in NJ?

Not always. According to NJSA 39:4-97, where a careless driving ticket is issued where there has been no accident or personal injury, the fine may be paid at the Violations Bureau by pleading guilty. If there has been an accident or injury, an appearance is mandatory. The ticket given at the scene will have a box marked "Court Appearance Required" or similar language to let you know if you have to go to court or not.
