To make things even more confusing the DOT is sometimes separate from the DMV, and sometimes not.

In Georgia we have the DOT that handles road construction etc..., and the Department of Driver Services that handles drivers licenses.

In Pennsylvania they handle both, plus tolls and even snow removal on the highways and major roads. I’d never heard of BMV before tonight and thought it was just DMV everywhere until I was twenty something.

You’re right, state bureaucracy is confusing!

To add to the alphabet soup you have DPS (Department of Public Safety) in Texas.

Washington DOL (Department of Licensing) checking in.

Or the MassDOT RMV in Massachusetts. (Which always has to be different, like calling itself a Commonwealth instead of a state and having a General Court instead of a state legislature.)
