Typically about 1-15 minutes from what I've seen. Yes that is a wait. But let me tell you this.
Call the DMV. Call them. Wait for 17 minutes to speak to a representative then ask to be connected with someone to pay your car registration and hold for an additional 33 minutes and then hang up frustrated becuase you just wasted precious moments of your life that you could've saved your ear from growing a califlower on it.
