In Georgia, all pure electric vehicles pay a mandatory Alternate Fuel Vehicle (AFV) fee. As of July 1, 2021 it is $213.70 and changes a bit each year. The AFV fee is meant to collect from EVs the equivalent of the average Gasoline Road Tax paid by ICE cars, but there is much debate as to its fairness. The AFV fee does not grant you any privileges.
If you pay the AFV fee you can request an AFV license plate - this is optional. You will pay a one time plate manufacturing fee of $25 plus you will pay an annual Special Tag Fee of $35 (in addition to the normal car registration fee of $20). The AFV plate allows you to drive in HOV lanes as a sole occupant.
If you have an AFV plate AND you have a PeachPass, then you can drive in the I-85 northeast HOT lanes for free. You still pay to use all of the other HOT lanes.
