HOV and Peach Pass are two different animals. Peach Pass is a pay for use ie Lexus lane that is only on I85 north of the Perimeter (I285). The HOV lanes inside the Perimeter are 2 or more passengers. Tractor Trailers are not allowed inside the Perimeter except for local deliveries.
The comment above is "not recomended", that is very different from prohibited. I was LEO with DeKalb County, one of the departments that patrol the Northern 1/2 of 85 running through Atlanta. APD only is responsible for a small portion of 75/85 through Atlanta. GSP is busy looking for tractor trailers and single passenger vehicles on the weekdays.
