I have avoided Rahway DMV since I took my driving test there almost 35 years ago. It was a mess back then, I can't imagine what it's like now.
I used to go to Rahway when my buddy was a Rahway cop. He'd tell me who was stationed there that day and I'd go drop his name to get pushed to the front of the line. Sadly, he's retired now, so I go to Springfield. I remember my daughter passing her driver's test and there was a 3 hour wait to get the license. So we took her documents and drove to Springfield and were out in 1/2 hour.
