The website just tells you what you need. You plug in your name, date of birth, and county, and it pulls up a list of what you need, and what is considered acceptable in each category. To renew your license you have to show up in person every so many years. In the interims, you can renew online.
I do purchase all our registrations for car, boat, fishing license, and the interim DL renewals online. It’s much easier than standing in line at the DMV.
Our DMV here in FL is great, and we hardly have ever had to wait. Sounds like your DMV where you lived in your state is awful.
