Can I register a vehicle in Salem's location now or do I still have to go to Turnersville?

I was there the other day to return tags. They said they are only doing license renewals and permits. They did take my tags.

No, from experience, they only do licenses. I was there this past Saturday. There are specific locations that does vehicle registration. I received a spreadsheet from Medford DMW with a breakdown of locations that does registration and licenses. I had to ride over 50 miles to Salem to get my CDL

Yes
