It has been illegal in jersey to have snow or ice on the roof of your car, truck or van ever since I can remember no matter how much or little it is. I know a few people that have gotten tickets for it and a few people that have been let off with a warning. Plain and simple, don't be lazy and have the respect to remove it before it becomes an issue. Now with Jersey doing away with the safety inspections there will be more and more tickets handed out for stupidity, procrastination and laziness, no matter how asinine.
