Been going to NJ MVCs for 10 years now and I've mostly used the Lakewood, Eatontown, Toms River, and Trenton locations. I've always had pleasant experiences.

Yeah, it can sometimes take a while to get through those lines (before they did the appointments, at least) but its typically painless for me. I research what docs I need beforehand, bring just those and a pleasant attitude, and breeze my way through every time!
