No you won’t go to jail lol you can get a lawyer to fight it for you they will knock it down to lesser charges. Lesser meaning “no point” tickets. These tickets will cost more but the important thing is to keep points off of your license as this will increase your insurance premiums sky high. You will save more in the long run taking the no point tickets. You could also try to fight it yourself, it’s difficult to do but not impossible and nj has set up a system online to appeal tickets njcourts.gov
