In Ohio in the past couple decades I had to wait behind two people once. Other than that I had an open window or just a one person wait. Most plate renewals are handled online and you only need a license eye test every eight years (instead of every renewal at four years like previously)
My daughter needs to renew her license and get real ID. I did mine through AAA a couple of years ago and I was in and out in no time. She tried to get an appointment today and nothing was available at any of their offices until June.
