How do I apply for an extension for my renewal car registration?

Google your questions...

Yes call try to get an appointment so it goes faster if you can't do it online or kiosk because I couldn't and without an appointment you will be there from 30 minutes to over an hour easy. I was there about an hour and half in the afternoon. Go early make line if your walking in

I would call 1st, go in, or last thing online
