N.J. D.O.C. vans and cars are often seen around here, as there is a maximum security prison downtown. I’ve sped past them before without a chase, so I’d guess they’re not in the business of writing tickets. They use an all-red light bar, with some white and yellow lights on it. However, in 3 years of driving on these roads, I have seen only a handful total of state and city police. 1 or 2 times in that time have I seen people pulled over. Despite the city’s claims, it’s fair to say that speed enforcement is lax. Be warned, as I have noticed an increased police presence here in the past few months.
